until next time, you can find us online at aljazeera.com/ajamstream. >> good evening everyone. welcome to al jazeera america. i'm john siegenthaler in new york. doubling down. russia ignores demands from the west and reportedly sends nearly wise as many troops into ukraine. support from the kremlin, the russian parliament backs a plan to split crimea from ukraine. millions of young women at risk. we hear from the former first daughter who is trying to help.

>> challenges du hi. keeping stoned people from behind the wheel. and 81 -- and young talents on the biggest stage of the art world. and we begin tonight with the very latest in the tense tug of war over crimea and ukraine. there have been talks of sanctions and days of diplomacy trying to convince trowz pull back -- russia to pull down. almost twice the last count from ukraine's government. today moscow warned washington that sanctions would back fire and hit the united states like a boomerang. there is another standoff in the military base of sevastopol.

jennifer glasse is live there, in crimea. jennifer. >> john, that happened earlier this evening. we saw armed men go into a base in sevastopol, they negotiated with the service people inside. we are seeing this kind of pressure all across the crimean peninsula. this comes a little left -- we've got a referendum in about nine days' time and the people of crimea will decide whether to with russia or stay with ukraine. that makes people nervous. >> vladimir lenin, here some people are worried history might repeat itself. communist leader, in 1944.

>> translator: not so long ago when the tatars were depoeted from crimea, the same thing happened. people were thrown out of their homes. >> tatars came back here in the '80s and '90s, so far it's been quiet. the tatars hi history of oppression, a crimea affiliated with russia. this minority group was hoping for international support but is certain it won't come in time. >> translator: if putin makes any decision, it's paid in the morning and in the evening, it's already implemented. no democracy, nothing. european union or osce organizations it takes months. by then it will be all over.

>> and things are moving fast. the city of sevastopol voted yesterday to become part of russia. broad forward by the -- brought forward by the region's pro-- russia parliament. >> considering the geopolitical region, we decided the sooner we are done with this vote, the quieter it will be. the people will be safer. >> not an ideal environment for a referendum. michael works to bring workers to sevastopol. he says the crimean people aren't in control. >> after all this is the game between russia and the united states. they are the major players of this game. if they come to good agreement, then definitely, everybody will be happy. >> here in this naval city and

across crimea, there is no agreement in sight. and growing concern that the longer the military standoff continues, the harder a diplomatic solution becomes. now, john, the minorities like the tatars are hoping the international intervention might help. but ofor the second day in a row, osce military observers were turned around at the border. if there is any indication that crimea is becoming a military state, more turn towards mowrm,, not leave from the international terminal. >> now the former u.s. ambassadors to nato, robert punter, joins us from washington, d.c. ambassador, welcome. >> thank you very much. >> do you prey away you heard in this piece, that this is a game

between u.s. and russia? good yes, i think it is. from the u.s. point of view, we want to make sure that international law is respected, that the integrity of ukraine is respected, and people have a chance to choose their future as a unitary state. from the russian perspective this has a lot to do with respect. quite frankly over the years some countries in the west and sometimes the united states as well has taken advantage of russia because they lost the cold war. so mr. putin is saying right now okay, i'm going to show you something where you're going to have to take me seriously. which leads me to think that with nine days between here and the referendum, that's a lot of time to play with if grownups in washington and grownups in moscow get together and work something out. >> what do you mean grownups in

washington and grownups in mowk, do you suggest -- moscow, do you suggest we don't have grown juiveupsso far? in we tried to drag ukraine in our direction, instead of people saying we have to sort out over time -- >> let me delve into that a little bit more if i can. the united states broke the rules how? >> you may recall the overheard phone call of the united states, assistant secretary of state and the u.s. ambassador to ukraine, talking about how do we put together a government that's going to do what we want it to do? i think that thing got leaked by the russians saying calm down let's back off. the real villain of the-of this is putin, no matter how this comes out, he and russia are going to pay a heavy price

because nobody is going to trust them for a long pest. but after the cold war, figuring out a place for ukraine which would be favorable to the west and favorable to russia we let it go by. instead of saying to the russians you'll have a pace in the outside world we tended to stigmatize them. well, putin is now taken a huge mis-step, question how do we help him take a step back and have a future for russia. we can all work with it. >> you talked about authorizing sections yesterday, the eu talked about sanctions yesterday, today russia doubles down. is that the intended consequences? >> secondly, sanctions only work if everybody agrees to tell. we already know that many of the europeans will not go along with

sanctions. and as a result, they won't work. except what i call exist tensiol sanctions. tomorrow morning, people are not going to trust the russians, not going to trust mr. putin for a long time to come. this has been in my judgment a big miscalculation by putin. trying to get respect perhaps but doing it the wrong way. he is going to pay a heavy price and russia will pay a heavy price no matter what happens now. >> mr. ambassador, thank you for being on the program. richelle carey with the headlines. >> malaysia airlines says it has lost contact with one of its

planes. the boathe boeing he 777, expeco land two hours ago, the exact plane that is now missing, a file photo. we will continue to follow that for you. ment venezuela accused of using force against antigovernment protesters. yesterday a motorcycle driver was shot and killed in caracas. he and other bikers were dismantling a barricade put up by antigovernment protesters. the government says the protesters arprotesters are usie gangs. >> 175,000 positions still the

unemployment rate edged up to 6.7% from 6.6% the month before, analysts says that is because more people started to look for work. the number of people who have been out of work for six months or more, rose to 3.8 million. the second day of cpac, hosted some pretty big names, among them senator rand paul. >> yet as our voices rise in protest, the nsa monitors your every phone calm. call. if you have a cell phone, you are under surveillance. i believe what you do on your cell phone is none of their damn business! [cheering and applause] >> other speakers today included rick perry, mike huckabee and rick santorum.

>> rain, ice and snow all hitting north carolina today. the freezing rain and snow began today, knocking out power to half million customers. the governor is calling aivstate of emergency. kevin corriveau has been tracking this storm one more time. what can we expect? >> the good news is it's going to be a short-lived storm. take you into the future and see what we're seeing. 18 hours ago, this is what the storm looked like. the pink indicating what we were seeing in terms of icing. now 18 hours later, the storm is actually making its way across the coast. take a hook at all the storm damage. the purple is either snow or ice damage as well as indicating the flooding. over the next several hours the

storm system is going to be making its way over the coastal areas. a lot clearer air and better skies coming into play here. temperature-wise tomorrow, there is going to be warmup. raleigh 64, richmond, 64. >> kevin, thank you. coming up, a former first daughter, shines a light on millions of women at risk. barbara bush is up next. >> have you thought about putting that phone down and unplugging? welcome to the 24-hour day of unplugging. that story is just ahead.

>> every sunday night, al jazeera america brings you conversations you won't find anywhere else... >> your'e listening because you wanna see what happen... >> get your damn education... >> talk to al jazeera only on al jazeera america >> oh my... >> sexual violence, some say it's become a global epidemic. 150 million girls worldwide have experienced some sort of sexual assault. lisa stark reports. >> i think it's important for me to claim it. because so many people are afraid to say that they're a rape survivor. >> her journey from victim to

survivor has not been an easy one. but she feels speaking out has helped her heal. she says she was sexually assaulted twice. first by her boyfriend during her freshman year at the university of pennsylvania. >> i said no repeatedly but i still felt like i couldn't come forward and tell people that i was sexually assaulted because i few him. i just kind of covered it up and tried to move on. >> reporter: then again during her junior year abroad in kenya she was attacked by a casual acquaintance. >> it was a violent, much more violent encounter. i couldn't rationalize it away that it wasn't rape. >> she knew her attacker in both case. >> as a young woman you go out on your own and someone will attack you on the street. when actually you are much more likely to be attacked by someone you know. >> trying to highlight and

combat sexual violence worldwide. >> we feel thi there is a bit oa ground swell. people are trying to pay attention. >> with the help of global health core, started by barbara bush, daughter of former president george w. bush. at together for girls, joya helped launch safe, an online women's magazine, devoted to sexual violence. >> stories are hard to read but with the idea that these people have overcome these things that have happened to them and have really failure ished -- flourished. >> who with her sister founded a group to help high school and college students build self esteem and to educate the young women about sexual assault.

>> statistically it is the number 1 crime happening on college campuses. >> it's a hidden problem. an estimate one in five women will be sexually assaulted at college. only 12% reported to law enforcement. it's because victims often feel they're the ones being blamed. both these women hope we are reaching a tipping point that increasing attention to sexual assault is forcing organizations to treat these crimes seriously and will encourage more victims to come forward. lisa stark, al jazeera, philadelphia. >> international women's day is tomorrow, and here to talk about some keys women's health issues is barbara bush, the daughter of george bush. it's good to have you here. >> thanks for having me. at global health care we are training a new generation of

global health leaders. trying to bring talent to the field of global health and ensure that our followers get trouble with the issues they care about, to make change on women's health issues during their career. >> how difficult is it how sensitive is it to deal with this around the world? good obviously women's health issues and sexual health issues are quite sensitive. that's why we think it's important that there is a new generation of health advocates that can move the needle. investing in their health not only are they healthier but their entire communities are. we find working on these issues is a game changer and can have a mobilizing effect. >> you told me this the last time. how would you characterize the

progress in the treatment? >> i think we've made unbelievable progress in hiv. ten years ago it was basically get the drugs you need if you were hiv positive in a developing country. now it's not a case at all. you can have access to anti-retrovirals in nearly any country you live. i think that's something that would be unheard of years ago. and it means that we can have an hiv-free generation when i'm alive in our lifetime i hope. >> a lot of the work that the fellows do in health education, right? talk about that. it's not just in africa but in the united states as well. >> absolutely. we have global health foal lows working in new york newark and washington, d.c, as well as subsaharan africa.

it is understanding the issues you need to know to live a healthy life. if a mother is going to have a baby and she is hiv positive, she needs education how to give birth to an hiv-negative baby. it's the right education to make the right decision. >> i was surprised the number of applicants you have for these jobs. it's a huge number. just like you, you wanted to give back and address global issues. there are a number of people there willing to do that. >> yes, i mean it's extraordinary. around the united states and around the world, these students want to use their life to make an impact. we want to launch great game changing careers in health. >> how do you think you would characterize women's health

around the world? good i think we've made tremendous progress in women's health. women have started to live equally long if not longer lives than men. which wasn't always the case. having healthier options, which is good for communities, that having been said, we have a long way to go. retained birth attendants, i think what's exciting is we have a long way to go but we also have the tools and the medicine to get there. we have great solutions to saving women's lives. now it's about getting to the last mile and doing that. >> where do you go next? do you get bigger or continue on that path? good we want to continue to get bigger. it saddens us, we only accept 2% of the people applying for the programs. we want to leverage people's

careers, and we know the more people we can get in global health and make sure our fellows understand navigating systems and changing policy to save lines then we can deal with the preventible and treatable systems that people deal with around the world. >> thank you for being here. >> thank you, i appreciate it. from slefng to computers to -- cell phones to the computers to the tv you're watching us on, allen schauffler, has tried to unplug over the last few days. how did it work, allen? >> well, it was a really interesting exercise, john. we're talking about the fifth annual day of unplugging. maybe a day we can all take to cut loose from the computer, maybe drop the space command for the television on the wall and

maybe just disconnect from this little thing which we spend so much time on. i did disconnect. it was interesting but i met a whole lot of people for whom unplugging was a matter of survival. >> by the time we met therapist cozette ray i had been unplugged for 24 hours. no faibing, no google -- facebooking no google mabs. >> what happens happening with your family, that's fairly normal. we have become very hyper-connected as a culture. >> breaking that hyper-connection account goal here, at one of the country's first internet-addiction treatment center. they say the waiting list is long. >> the point is to like

rediscover the things that make you human. >> for andrew fulton and others unplugging is a chance to get their lives back. there's counseling, intense physical workouts, daily anchors, connecting with nature. an intense video gamer, andrew spent weeks in his room, online. >> it's lying -- like a drug. it's depression. >> the virtual worth of social media, gaming and endless endles options. >> the american psychiatric concept says the concept of internet addiction still needs more study. but in countries like china and south korea. it's -- >> like an eating disorder. just because you have a problem

with food you can't say, i'm never going to eat again. >> ab drew reconnected with music. he is hoping that will reorder his life. >> there's that part of your life that says go on the internet, go see your friends, go watch youtube, the real world doesn't matter. >> as everyone learns that the real word does matter, they have a simple many bit of advice, do it. >> for one day, be present. and then i invite you to bring more of those days in to be present. it really will change your life. >> now, andrew and the others develop survival plans. they are going back into the real world, with plenty of outpatient counseling, by the way. the hand held connect sift a

fact we're going to have to learn how to deal with. for the rest of us, really easy, 24 hours, really interesting exercise. give it a try. >> i don't know how easy it is. why doesn't insurance pay for treatment? >> you know john, this is something that is not recognized by the american psychiatric association as something that's a legitimate psychological disorder. it's not yet described that way. there's a lot of disagreement about whether internet addiction is actually an addiction as classically defined. just not covered by insurance. >> allen schauffler, the space needle in the background and the sun said over the olympic mountains, it's a beautiful shot, allen, thank you very much. laws legalizing marijuana, force police. >> i'm looking at the white car

and the semi in front of us. >> adapting to driving while high and once an arrest is made, there's another problem. >> the thing is driving stoned and driving drunk are nothing alike and i'll explain why in a moment.

>> welcome back to al jazeera america. i'm john siegenthaler. there's breaking news we're fog this half hour. malasian airlines has lost communication with one of its planes. the plane is a boeing 777. it was expected to arrive in koala lumpur over an hour ago.

what do you know florence qux. >> we know that air control lost contact with the aircraft about two hours after it took off. it is deploying search and rescue teams to try and locate the aircraft. they haven't said yet where they lost contact with the aircraft and receiving conflicting information at the moment. they may think it's somewhere within the peninsula of malaysia. the aircraft appears to have entered air space controlled by vietnam. however, i stress that hasn't been confirmed by the airlines yet. they will be confirming, back in september 1995, when one of its planes crashed into a malasian

city, about 34 people on board. >> florence lu who is following this story from kuala lumpur . >> richelle carey is here with the top stories. richelle. >> u.s. statements to pressure it to leave crimea. the foreign ministry says sanctions announced by washington would back fire and hit the u.s., quote, like a boomerang. thousands of russians took to the street to show support of the issue, welcome the region's bid to split off from ukraine. russia is beefing up its presence, and kremlin troops there now number about 30,000. the pentagon says the number may be closer to 20,000. one pentagon official says one

ukraine defense minister is asking for technical military advice and disaster operations, john. >> all right richelle, thanks very much. many ethnic russians in crimea are already looking east and they are welcoming the troops from moscow. nick schifrin reports. >> on the gateway from russia into crimea, the unmarked green trucks all drive one direction. according to ukrainian intelligence the steady stream means that russia has emotional doubled its forces here. >> can you tell me where you're from? >> this is one of the ukrainian's eastern most bases. making ukrainian soldiers mise-prisoners in their own base. who supporters are happy to brave the cold. >> translator: there is no

ukrainian army left. he says so we need protection. if there's going to be a referendum on crimea's future this city has already voted, raised the russian nag on city hall. and this is the first city where russian troops arrived. an activate recorded russians taking over the hill. for igor, that same view is painful. his family's lived in this family for decades. first they were soviet and ethnic russians. and always looked east. it's painful when they make me speak ukrainian. today he reliance on a well. he accuses the ukrainian government of letting crimeans

live in the stone age. i don't believe in any ukrainian government he says, not the old one, not a future one, not the current one. thanks to these men he now lives under a new crimean government. they leave the local headquarters of the party that recently took over ukraine's parliament. constantine says he has 4,000 fighters. we can mobilize a big army within an hour he says. he wants to join russia because he believes crimeans are culturally different than ukrainians. >> we see homosexual people we don't want to live like those people. >> that hatred targets the city's few pro-western activists.

irina, last week, withstood a fears crowd. but not sure how long she can hold out. >> if this hapts, what -- happens, what will happen to you? she says will leave the city. but increasingly it has become a home for those who only just arrived. nick schifrin, kirch, ukraine. >> coming up. 11:00 eastern, 8:00 pacific. more on the crisis on ukraine, at aljazeera.com. sunday marks, levinson who turns 66 on monday served two decades with the fbi, working for a freelance spy for the cia.

in a statement his family asked iran for his safe return and says the u.s. government has a duty to bring levinson home. recreational marijuana has been legal in colorado for two months now. how high is too high when getting behind the wheel? carol mckinley has that story. >> reporter: this is not acting class. it's real life police work. >> now when i ask you to i'm going to ask you to tilt your head back and close your eyes. >> law enforcement special ops. a squad now being trained to recognize stoned driving behavior. they want to prevent accidents like this one which happened just days after recreational marijuana was sold legally. >> how does the law determine

between stoned and drunk driving? people have a harder time communicating. >> i introduce smief myself, tem why i stop him. he will tell me. and from that i get cues. i can't arrest somebody on an odor or couple of cues. i need to have a driving action. >> to get the word out the colorado department of transportation is unveiling an ad campaign, designed to keep people from driving high. the haw says drivers are impaired -- the law says drivers are impaired with 5 nanograms of thc in their blood. but they can try to convince a jury that they were not high at all. >> it's not the level, it's how the substance can affect

someone. i don't think necessarily if it's 5 nanograms or above or lower. >> for the marijuana community, the marijuana community is left not really knowing oftentimes whether they could be -- whether they're truly impaired or whether they can be convicted. >> reporter: so far in colorado there have been at least two arrests a day for driving under the influence of marijuana. >> we can all you know agree that people should not be using marijuana and driving. the same way that they shouldn't be drinking alcohol or prescription drugs or other illegal drugs. >> and with this graduation there will be more troopers trained to be on the lookout for people who decide to get high and drive. carol mckinley. al jazeera, denver. >> of course enforcing laws against driving impaired can be challenging, for one reason, there's not a lot of scientific consensus for marijuana's effect

on drivers. jake ward joins us live with more on that jake. >> john, it may seem open and shut, no one should be stoned when driving. but determining who is in fact doing so from a scientific perspective is a lot more complicated. there is very little research about how stoned is too stoned to drive. even in washington state, where initial 502 legalized possession of small quantities of marijuana. >> without a doubt. the science of impairment and marijuana is very unclear. and it's not obvious that it will ever get clearer. that we will ever be able to create a bright line standard. >> the science that does exist is spotty and contradictory. in the united states, discreet quality weed, away -- street quality weed, what we do know is foreign studies, even those are

highly variable. one study found the risk of accident may be higher if a driver has 5 nanograms or higher of thc in their blood. but experienced drivers may be able to drive safely which is very different from what we know about alcohol. scientists have a broad notion of what pod does to our driving ability. the automatic stuff begins to fall apart. it's the conscious stuff, turning a corner, domg a stop -- domg coming to a stop when we ae baked. >> this is why virtually every scientific or traffic safety agency that has assessed this issue that has posed the question, can we correlate behavioral impairment from the presence of thc or its net an

metabolite says, no, we can't do it. >> colorado and washington both decided on a 5 nanogram blood limit. nevada and ohio set it at 2 nanograms. >> we looked at the science, albeit fairly limited and we said what's a reasonable range and then we said, let's pick the top end of that range. what we are talking about is a standard that will potentially end up with an automatic standard for impaired driving. >> spot test for thc is not going to happen. it takes a full two milliliters of blood to test for thc and it takes an additional milliliter for any other blood you want to test for. the dream of a cop being able to

administer a test on the side of the road is in the distant future. groundbreaking on inconsistent science, something that other states will need to do. john, you can see the regime built on alcohol testing is not at all prepared for marijuana. >> jake, "baked" is a term that hopefully can be determined in colorado. >> marijuana is still legal illn federal law, you have to use special federal weed that's grown at the university of mississippi which is comparatively very, very weak. so we like to think that washington and colorado's laws will dean b deepen our understaf

what's going on but it probably won't happen. >> let's head to washington, d.c. yoinjoie chen standing by. >> good evening john. tonight on our program a game of risk, with the mastermind of the mean. meet ben huh. he lives off the thinking, carpe deum. an aha moment that left him with the notion he has something to contribute. that's that. cat pictures all over the web. also a lot of people making some pretty funny but dumb mistakes. a product he says is just part of the business. >> business is very simple. you want to make one dollar of profit because if you lose a dollar, if you are unprofitable every single day, there is an

expiration date. if you are profitable every day, you will never run out. >> on "america tonight." we'll see you then. >> joie, thank you very much. the up and coming artists at the whitney. marp peoplpopular people takingr stage. and a walk to the ice caves.

>> i'm meteorologist kevin corriveau. it is heading towards the weekend. we've had some warmer rain come in over the last couple of days, and what that is doing is melting the snow in the lower elevations.

in part of montana, you can see the light greens indicating flood warnings and in western washington, we are looking at flood warnings. saturday into sunday. temperature-wise though seattle 55° is what we expect to see. boise at 59 and billings add 55. now where we're seeing some very cold air still in place is up here towards parts of north dakota, minnesota, right now temperatures are into the teens and when you factor in that wind chill, fargo feels more like minus 4°. hopefully we'll see a slow improvement as we go especially towards next week. chicago is going to feel more like 27°. here across the northeast, a very nice weekend and those temperatures are warming up. that rain you see is going to stay off the coast. that's a look at your national weather, news is up next.

>> every friday we take time to appreciate the arts in our friday arts segment. and tonight, one of the art world's most prestigious shows opens to the public. the whitney biennial. it is home to the country's most famous modern art collections. this is the grand opening of the whitney biennial, which showcases dozens of up and coming artists. we talked to one of them, david

mckenzie, in his studio in brooklyn. >> i was shocked to be in the biennials. it doesn't happen every day. you don't get to be in every major exhibition. i make performances and i make videos. so the piece called camera, the work is a video in which i document finding myself at an event with henry kissinger. i think with the way technology has you know changed our lives, obviously people are documenting everything all the time. what we have sort of lost i think in some way is why we document. when you can document everything i think in some ways you get people walking around the museum taking pictures of paintings and sculptures and perhaps delaying the experience of actually looking at those works of art. when people come to the museum and see the shows, see my work, i hope they think about how

history has created an archive. the whitney also chose a video called the beautiful one has come and it is me in a museum in berlin that is housing the nefertiti bust and me walking through an abandoned building and sort of marryin marrying tho images together. i hope people will look at how we choose to preserve some things and let other things fall to ruin. >> i'm carol jackson. an artist who works with paper mache and leather. they are not even possible in the real world but how we might view the past like these great moments frozen and no one's looking anymore. and they can see tear current world but almost completely

empty of any human life. or form. or culture. the motion of a middle class is like then a kind of declining way of life. i'm not suffering, but it certainly -- things aren't as available as they were to my parents or other generations. to be in the whitney is a huge honor. and nothing bothered me. i was free of in your owes east, and i -- neurosis and i felt fantastic. there's definitely a certain reward of just making art and having people look at it and participate in it that way. >> now, anthony elms, one of the curators for this show at the whitney biennial. he told us what he's most proud

of in the exhibit. >> the one thing i'm proud of, any chance that i have to bring forward artists that i respect. so i have a very large stage in which to put 24 people who i think are the most interesting makers in the country to get people to pay attention to their videos to their paintings to their sculptures to their theater pieces to their dance pieces. >> tell me what the biennial is? >> it's a long running attempt every two years to say where are we now and where is artwork in this country now ghm and where is it? >> it's all over the place. >> some people in the bis enial are known for their work as writers and film makers. talk about that. >> there is an author in gary,

indiana. we were interested in saying, there are people for whom a plurality of mediums are important. just like on our computers, we might be watching a video at the same time we're trying to type a document at the same time as we've got a newspaper open in the back window. people are sort of making across all medias at the same time. >> several of the works address transgender and homosexual issues. can you talk about some of those? >> i guess you can say i've got -- sort of queer sensibility is becoming more visible in the art world as in everywhere. it's deep rooted in makers right now. >> what does this mean for the whitney? >> the last show they'll have in the broward. they're going elsewhere.

>> that's where most people know of the whitney. >> it's not just the whitney has been there, it's an historic landmark. it is a building that's regarded as an architectural treasure. >> how has the art world changed in the last five years? >> i.t. particularly changed, and it has really changed video. video editing happens digitally. massive large video cameras, now he can make his videos on an iphone. >> some people may have this image of art as a painting, in a museum that hangs on a wall, done by one artist and that's art. good that is art. >> but what you're talking about is so much bigger. >> it is bigger. the art world has been expanding for years. one of the reasons the whitney

has to move to a businesser building is the broward was built in 1963. it's not well suited to theater pieces or dances. the art world has changed and the whitney needs to capture that. >> our thanks to anthony. on to other news. the winter paralympics. despite the tensions between ukraine and russia. russian president vladimir putin visited the olympic village, took part in the flag raising and visited a medical tent. ukraine sent out a single flag bearer to represent its team in the paralympic parade. thousands have walked more than a mile over frozen lake superior to catch a glimpse of

caves dripped in icicles. these boats are typically only accessible by boat. on the weekends the ice caves are attracting 10,000 people day. that's more than any other day in the park's history. in just a moment, we'll have an update on the misser airliner over malaysia and coming up all new on the newscast at 11:00, eastern, 8:00 pacific, a texas man tells us about his fight with the judicial system to help others. tonight's freeze frame, an image from belbek, bueno buenos. the headlines next. that open your world... >> this is what we do...
