>> the u.s. and world leaders stepping up sanctions against rush over the crisis in ukraine. earlier today president obama announced measures that would target individuals an there. 17 individuals in total have been targeted. >> the goal here is not to go after mr. putin personally. the goal is to change his calculous with respect to how the current actions he's engages in could have an adverse reaction on the russian economy in the long haul. >> mike viqueira has been following the president. he's in m manila. the first round of sanctions did not stop vladimir putin, so what

makes him think that the second round will be different? >> reporter: this is a gradual approach, to ratchet up the pressure. over time it will change russia's calculous, and they'll realize that this is a dead-end. you're right. this is a criticism that the sanctions don't go far enough. they have been pushing for broader deeper sanctions. now the white house has talked about what has already happened as a result of the individuals who have already been sanctions. there are several more individuals in in round of sanctions along with the 17 entities that you mentioned. but those entities are those who have been sanctions before. the gradual spreading out, cronies of vladimir putin, cronies and olagarts in the

russian economy. it has already cost the russian economy $60 million in investment flight, the credit has been downgraded. and gdp has been downgraded. what has already been done has had some bite and adding to it this evening. >> the president is trying to build that united front when it comes to rolling out the sanctions. as we've been reporting, europe has deeper economic ties with russia than the u.s. are they willing now to be part of the united? >> well, this has been the problem all along, del, ever since the president went to europe last month. there are two entities, the g-7 as well as the e.u. he got the g-7 to at least threaten the broader sanctions and what would trigger that, but

white house officials say if russian troops were to eaggravatto invadethat have beer some time, then that's the time to bring the e.u. along. getting europe to go along with something that cuts much beeper that would have an adverse economic impact not on russia but world economy that is a much tougher sell. >> mike viqueira traveling in the philippines. ahead of those sanctions there are rising tensions in ukraine. ukraine's second largest city, officials say who they believe is behind the attack. and an tv station in donestk has

been seized on sunday. the ukrainian government said they had blocked russian channels saying that they serve only for the kremlin. severe weather stretching from des moines, iowa, to new orleans. the federal government is now ready to help. >> i want to offer my deepest condolences to those who lost loved ones. i commend the heroic efforts of verse fonders and maybes who rushed to help. i want everyone affected by this tragedy to know that fema and the federal government is on the ground and will help our fell americans in need working with state and local officials, and i want everybody to know that your country will be there to help you recover and rebuild as long as it takes. >> most of those who died live in arkansas. massive tornadoes hit little rock, and some people there lost

everything. [ sirens ] >> a tornado nearly a mile wide tore through an area outside of little rock, arkansas, for nearly 30 miles. this couple rode out the storm in a safe room they built a couple of years ago. when they emerged everything they owned was gone, including their home. >> we're alive and we're so greatful and thankful. >> reporter: the similar scene of twisted metal with cars just turned upside down. >> i've seen houses literally picked up and set up on top of cars. the garage is in the yard. >> reporter: emergency crews searching for residents who still need help after after a y

tornado was spawn there had. >> i said tornado, and everything was hitting. >> reporter: you see the powerful twister, at least two people died there. sunday ace storms came two days after the same storm system slammed into north carolina. multiple tornadoes across the central and eastern parts of the state destroyed more than 200 homes and killed an 11-month-old boy. >> it broke my heart because i lost everything. thank the lord for not having me be because i probably wouldn't be standing here right now. >> reporter: as some communities begin to pick up the pieces other brace for the next storm to hit. since this slow-moving system is not over yet. >> as many as 24 million people live in the path of this latest severe weather, and we're not out of the woods yesterday. we're joined now, eboni, this is the beginning of the bad season. >> reporter: that's right. we're beginning to ramp things up as far as severe weather is concerned. we've had a number of reports. 30 reports of tornadoes just yesterday alone, and that was

from iowa, kansas and missouri. here's a look at what we had yesterday. through arkansas we had a line of tornadoes we were reporting, but we're probably going to find this is just one long track tornado. but then up to the border of kansas and mohamed morsi, w mise that tornado off in the distance and it reportedly turned over a railcar. a lot of damage down in some parts of the midwest and deep south and we're expecting to see the system bringing more severe weather. showing you the maps with what we're dealing with today. the broad area of circulation, we have the warm air mass that is ripe for more storms. we have storm watches for parts of mississippi into indiana until noon. >> the anger and outrage of the

clipper's owner's comments. they wore their practice jerseys inside out. we have been following the controversy and the calls for action. we're joined with me. >> reporter: a lot of rage and outrage the la clippers have decided to cancel today's practice. now nba commissioner adam silver is still trying to identify the voice that is been alleged to be donald sterling. after the loss, doc rivers said that his team was not mentally or physically in the game. >> reporter: there was no excuse. that's night fault. i got to do a better job. whatever the distractions, i got to do a better job. i didn't do my job tonight.

i take that personally. >> now doc rivers said it's his responsibility. he took ownership of the loss, but he said going back home is jukely a safe haven fo have usue is usually a safe haven, but he doesn't know now. >> sterling would have the right to challenge any concerted action of other owners in antitrust court, and that would be a powerful and winning argument. i don't think there has ever been an suspension of an oner in sports where they have antitrust rights. in baseball the commissioner has more powers, but i haven't seen a commissioner take that most powerful action against an owner in other sports. >> reporter: ross, here's the dilemma. if this was a player, he or she would be out. this is an owner, what other

options are on the table? >> right now the nba is in uncharted territory with donald sterling, but there have been owners in other league who is made racist comments who have been suspended. eventually an owner was forced to sell is the team. yank key's steinbrenner was banned from day to ba day-to-day operations by the commissioner after it was learned he paid a gamble $40,000 to dig up dirt on a someone who he has had a running feud. what can be done they're still trying to determine. >> magic johnson said the owner, in this case donald sterling,

should give up this team. that's not going to happen. pausing to honor and remember the 6 million jews who died in holocaust. many stood silent during the air raid siren. it began on sunday at sundown. and israeli prime minister benjamin netanyahu and the president shimon peres paused at a holocaust ceremony in jerusalem. those who died will be read in parliament. half a million holocaust survivors are still alive, many of them living in israel. >> each one witnessed the 20th century's darkest days. each one survived. each one says their struggles still are not over. >> the faces that i hope never

forgets. i think its powerful enough to make a change. >> half a million holocaust survives still alive, 200,000 live in israel. they struggle for dignity and respect even in a state created as their safe hayen. >> they survived the holocaust, what they have to do now is also be survivors. >> the caption details how they fight the government for stipends or how they've given up getting the help that the state owes them. >> she has many, many bureaucracy problems with the government. but on the other hand she's very, very proud. she's so sad. she lost her husband like the year before this photograph. and she feels so lonely. >> i see a man that is trying to overcome very difficult era in

his life, and because he doesn't like to talk about it, so he puts it on paper it's very powerful. >> a painter, the granddaughter of a survivor was his mousse and >> i suffered so much, i don't feel like suffering more. >> 200,000 jews were slaughte slaughtered. he survived in the labor camp like those in his paintings. >> you don't move. if you move, the suffering was terrible. three years on the labor force. you are not yourself. >> he arrived in israel excited. he felt like he was home. he became a famous painter, but

70 years later he said the governments abandoned him. >> the government, you don't get nothing. nothing. in response to that anger the israeli governor said it would increase medical care and hand out an additional $300 million. but many say that improvement must be followed by more before it's too late. >> we're giving them voice, we're giving them visibility because we believe its like the last chance. it's a generation that is fading away. >> nick schifrin, al jazeera, jerusalem.

ferry. in pakistan three students were killed at the islamic seminary in karachi. no one is claiming responsibility, but in parts of pakistan, violence is an every day occurrence. now residents are trying to decide how to best protect themselves. >> this 4 by 4 jeep was stripped to its frame. they'll install bulletproof doors and windows and beef up suspension to cope with the 1,000 kilograms of stee steel ad glass that has been add: in karachi, the city has a long history of violence. but in recent times the taliban has also grown in influence. just last year more than 2,000 people were killed in attacks,

and around 100 were abducted for ransom. the killings and kidnaps she no signs of slowing which means those whwindows that can stop a. >> reporter: over the past year he has seen a big increase in the demand for armored vehicles. >> now i think that people have really become aware that such an investment was quite necessary. especially if one can forward it. >> armoring a car is not cheap. the cost is anywhere from $30,000 to $40,000. and that's on top of the purchase of the vehicle. but it's a small price to pay for peace of mind.

said khan, not his whale name. he has asked to not to reveal his name. >> i have asked in the last two and a half years the time comes when you feel enough is enough and you have to look for a solution. >> in a country where many people live on only a few dollars a day it's a solution opened to a privilege few. al jazeera, karachi. >> coming up on al jazeera america. a new study taking a closer look at all those busted knees, and why girls playing sports seem to suffer more injuries than boys. the details coming right back.

>> welcome back. i'm del walters. u.s. is slapping tough new sanctions on russia on putin's inner circle. businesses targeted as well.

president obama saying the sanctions are the next step in an effort to change russia's behavior. the nba investigating claims the owner of the los angeles clippers made racist comments. the team was playing the golden state warriors. today's practice has been canceled well as well. tornadoes killing 16 people. arkansas was hard hit with more than a dozen people dead. the question now is, is it over? we're joined now with the latest on where these storms are tracking. >> del, it looks like we're going to be dealing with the same storm system with the next 48 to 72 hours. we're not done as we speak. we're dealing with storms that have been blowing up across mississippi into memphis, and we're just really getting started. this circulation is a broad one, and we've been watching it circulate here across the center of the country lifting off to the north and east. we have the warm moist air and then on the backside we have that push of colder air, that's

what is helping to bring snow in the parts of inter mountain west. but the storms are not going to be slow moving. storms have been racing off to the north and east where we've seen severe storms in the memphis area. we'll be dealing with the heavy rainfall and things are going to be changing and econtrol offing right now we only have a tornado watch in effect until the non-hour across centralized areas of mississippi. we still do have time before the tornado watch is out. things are going to be changing very quickly. that's why it's going to be a good idea to stay alert. here's the set up.

parts of texas, although we're getting that push of air we're expecting to see really some strong temperatures as we go through the day. south texas near san antonio, near record heat. by the time we get into the day on tuesday the severe weather pushing to the east. tornadoes will be a possibility into the atlanta area and also western areas of florida. again, del, this is something that we're going to be tracking over the next several days. >> thank you very much. now to that study involving busted knees that so many people are talking about, a growing number of younger athletes being sidelined with acl tears, that devastating knee injury that requires surgery and rehab, one group of younger athletes are getting special attention. john henry smith reports there is a new set of guidelines to keep them from getting hurt.

>> i really love sports. i love playing them. i love being around my teammates. >> but if the first game of high school soccer season this past fall, gaby suffered an injury that would deprive her of sports her senior year. >> the defender hit me in the side of the knee with her knee. i heard two pops. >> gaby had torn a primary stabilizer in her knee, her acl. an injury that her physical therapist said is a greater risk in girls than boys. >> they're six times more likely to injury themselves than boys. they have a wider pelvis and that causes them to collapse their knee in when they land and cut. that's a contributor. they have imbalances that boys don't have for whatever reasons. their quadriceps tend ton

stronger than their hamstrings. >> acl injuries have afflicted four other athletes. >> we're not teaching the kids until the age of eight years old the proper exercises to strengthen the leg muscles in the right way for the girls. >> an article in the may edition of the american academy of pediatrics monthly journal hopes to change that. dr. cynthia labella is the lead author. >> recommending that young people who play sports who are at high risk for acl injury, sock, volleyball, basketball, participate in neuromuscular training programs, which is a series of exercises that strengthen the key muscles of the niece before they participate in their sport. >> you can increase injury risk by 70% to 80%. >> reporter: he has long advocated the use of such

exercises in their physical therapy exercises. you see them land and they collapse in. they can be trained to land properly. >> the incentive to encourage acl prevention techniques is high. >> if you're 15 and you injure your acl, in your 30's you can suffer the effects of oste osteoarthritis. >> the rash of acl injuries has raised awareness to a point. >> a lot of us have been taught now at least or have had access to teaching, but i think some girls it doesn't register with them. that's fine. i think i would have been one of those people had it not been for my injury. >> we're following a developing news story, north carolina, ant university now on lockdown.
