[ speaking foreign language ] armed groups fighting against the government say syrian troops are shelling homes and terrorizing residents with snipers. humanitarian groups and aid workers say the situation is getting worse. at the moment, cnn has no reporters and no cameras inside syria. the government strictly limits access right there.

but i want to show you one way we are able to bring you images of the fighting. freelance film makers, sometimes amateurs with video cameras, release their material for the world to see. this was recorded in homs by a very brave french film maker. his name is manny. [ machine gunfire ] >> reporter: urban guerrilla warfare like this is relentless and terrifying. the fighters appear fearless and take crazy risks. but they still find time to look out for manny. [ gunfire continues ]

back at the headquarters, the battle is raging. free syrian forces have detonated a bomb below the roof top position where government snipers are trapped. after more than 12 hours, the snipers are still putting up a fight. [ gunfire continues ] casualties are mounting. free syrian fighters have entered the government's security building. [ horn honking ]

[ gunfire continues ] it's room-to-room fighting now. stairwell-to-stairwell. it's a humiliation for president assad. with bullets still flying, fighters make off with boxes of much-needed ammo. >> the morning after.

the secret police building has been gutted, as has the local post office. down the street, there's a long line for bread. with parts of the city besieged, you can no longer get to shops in neighboring districts. >> a couple of blocks away, and you're in a district where many belong to the president's sect. they have not been attacked. homs, now a patchwork dividing along sectarian lines. this doorway is as far as sunni muslims can go. for them, one step into the street and they're in sniper alley.

>> it is truly unbelievable what's going on there in syria. we also want to tell you that cnn has learned that american journalist marie colvin, who was killed wednesday in homs, will likely be buried in syria, according to her mother who said aid workers have been trying to get her body out of the country but it's just too dangerous. two american officers shot dead in afghanistan, not on the battlefield but in a place where they should have felt most safe. at their office inside a highly secured government building. and the person who pulled the trigger is still out there. our own nick patton walsh is standing by in kabul where this all occurred. nick? >> reporter: a day of much confusing at times contradictory information. what has emerged is two americans have been shot dead on the afghan ministry compound, on a secure part of that compound where western forces have some of their training personnel. the taliban have leaped forward

to clean responsibility saying the gunman was working for them, naming him as abdul rachman, saying he was acting in revenge because of the burning of a koran that happened a week ago on a u.s. air base. unintentionally the americans say, just east here of kabul. that, of course, not something which can be confirmed. they say the gunman was not a westerner and that he is at large, he escaped from the scene of the crime. this may suggest he is perhaps an afghan and we have heard from across the atlantic a statement from the u.s. department of defense that the afghan defense minister has pledged to cooperate in this investigation and has apologized. but really this plays into the larger issue of trust between americans and afghans. nato, in a real rush here to get afghan security forces ready to take over security to they can begin to withdraw. an instance like this just damaged that vital relationship. today, already we see a reaction

from the commander general john allen, withdrawing all his military advisers from ministries in an around kabul as a precaution. in fact, it could begin to impact that vital training mission. but the real impact is going to be psychological on u.s. and nato soldiers. they've already seen an increase in instances which men on afghan uniforms turn their weapons on the soldiers who are training them. this isn't going to help, this is a place where they should have felt safest and it's occurring in this climate of protests across the country. again today, protesters violent aapproaching the u.n. building, clashes there resulting in the loss of life of five protesters we understand, many others sured. really this instance happening in the secure afghan interior ministry is going to play heavily on the psyche of many nato soldiers here. nick paton walsh, cnn, kabul.

misdemeanor charges after he got into some sort of altercation with two nurses as he tried to take his newborn son outside of the hospital for a walk. earlier cnn's susan candiotti told me how it went down. >> reporter: well, the question is, was he defending his rights as a parent and protecting his child or refusing to follow a nurse's order? douglas kennedy was visiting his wife molly in the maternity ward two days after her c section and said he wanted to take his baby outside for fresh air. it was about 7:30 on a saturday night last month. it was in a hospital in a new york city suburb. baby beau was swaddled in a blanket and cap. kennedy says some nurses were willing to let him go. but when others disagreed, things took a nasty turn. in sworn depositions to police, nurses convinced him to leave an elevator and took him to a stairwell and that's when things got physical. >> the father grabbed her wrist

and arm and twisted it so severely she had tremendous pain in her arm. she then backed off with the other nurse standing right there. the gentleman proceeded to kick her so hard with so much violence that she flew through the air and landed in the middle of the corridor. >> kennedy's lawyer says he was trying to protect baby beau and used a knee, not a foot to stop the nurses. who were grabbing for his baby. >> the only aggressors were the nurses and the nurses said he could go outside and it only changed when another nurse and another nurse after that became aggressive and blocked douglas from walking with his baby outside to get fresh air. >> the nurses told police the baby's head was shaking violently from side to side. kennedy's lawyer denies it, saying the baby slept through the whole thing.

attorneys for both sides agree that the baby was not injured. an emergency room doctor who saw what happened defended his boyhood friend in a statement. quote, the nurses were the only aggressors. to charge mr. kennedy with a crime is incomprehensible. seven weeks later, the local d.a. charged kennedy with a misdemeanor for child endangerment and harassing the nurses. >> our thanks to susan candiotti for that report. news out of pennsylvania. an official with the catholic archdiocese of philadelphia is asking a court to throw out child endangerment charges against him. attorneys say a 1994 memo shows he created a list of problem priests, but a cardinal destroyed it. he's accused of keeping priests who abused children in the ministry and transferring them from parish to parish. this is the first case in the u.s. that charges those who were accused of failing to stop the abuse, not just those accused of abusing.

in an election season, headlines become key ingredients for campaign promises. but with the price of gas skyrocketing, can our government do anything to lower the price? athena jones looks at if or when washington may be able to get you some relief. >> reporter: as prices at the pump rise, so does the political rhetoric on 2 campaign trail. >> they're saying by the summer drive time, it will hit $5 a gallon. >> i have developed a program for american energy. so every american can look

forward to $2.50 gasoline. >> reporter: and in washington -- >> gas prices have doubled since the president took office. >> reporter: average gas prices have risen some 40 cents a gallon over the past year, and boosting domestic energy production is an important topic of debate on capitol hill. >> gas prices are so important because it's such a tangible and real impact on people's lives. they can feel it. it affects their everyday life. that's why it's such a political issue when it comes to fighting between the two parties. >> reporter: the republican controlled house passed a bill that would increase offshore drilling, open the wildlife refuge to drilling, and fast track approval of the keystone pipeline. this would not bring down gas prices immediately. experts say if only way to do that is cut the gas tax. but they say that's not necessarily a reason to reject them. >> to judge the merits of a long-term project on the basis of whether it would have a short term impact, that's like not saving for retirement now

because you're not retired. >> reporter: the measure, part of a larger bill yet to reach the house floor, faces stiff opposition in the senate where democratic lawmakers are working on their own bill. president obama has touted what he calls and all of the above approach to the energy policy. one focused on increasing domestic production, improving car efficiency and developing alternative sources. he said america can't drill its way to lower prices. >> while there are no short term silver bullets, i've directed my administration to look for every single area where we can make an impact and help consumers in the months ahead. >> reporter: on wednesday, three house democrats sent the president a letter asking him to develop an aggressive strategy to release oil from the reserves. the white house says they've taken no response off the table. atho athena jones, cnn, washington.

>> gas prices will be a big topic sunday morning on "state of the union" with candy crowley. she will ask if the president successfully made his case to fight rising prices or $5 will become the norm. that begins at 9:00 eastern. don't miss that. just three days to go before a pair of key primaries in arizona and michigan. rick santorum's national lead has shrunk to a single point. it's that close. the survey shows santorum leading mitt romney 31% to 30%. santorum had a ten-point lead just three days ago. it's ever changing. in arizona, the news for romney could be better. he's still ahead of santorum, 39% to 35%. but his lead has dwindled by three points over the past ten days. and here's where romney has real trouble. in michigan, where he's from. the latest arg poll has him trailing 38% to 34%. factor in here margins of error,

and it's a toss up in arizona and michigan. losing michigan would be embarrassing for mitt romney, considering he was born there, raised there, his father was governor there. our joe johns is standing by in troy, michigan. joe, many thought this would be a slam dunk as you can imagine for romney just a few weeks ago. what is he doing now for a last ditch effort? >> well, you know, he's had problems with evangelicals, with social conservatives, who viewed him with suspicion somewhat. but he's had problems connecting with audiences. i talked to one man in this audience here in troy, michigan, where romney appeared today, who said he feels as though romney can be canned, if you will, and he compared him to rick santorum who said he sounded more spontaneous, more authentic. so what the romney campaign has been trying to do is find ways to help the candidate connect. one of the big ways is bringing out one of their so-called not so secret weapons, that would be

ann romney, who is the wife of the candidate. they brought her out here in troy, michigan, and she really warmed up the audience and connected with them. listen to the sound bite. >> a year ago when we were making that final decision whether to step forward and do this again, it was a tough decision, because i told mitt four years before, i was never going to do this again. he laughs and said, you know what, ann? you said that after every pregnancy. maybe i should just do all the talking and let him stand here and watch me. i've also decided no more debates. if we're going to do another debate, he's going to sit in the audience and watch me. and that will be it. >> reporter: she does have an advantage, though. she, like mitt romney, grew up here in michigan. so she was going to be received warmly, especially in this place. >> joe, i think that was a great move, ann romney very funny, kind of warmed up to the audience there. and i know they're trying to

humanize mitt romney, but it's almost like he has so many missteps. you want to just cringe. he was talking about being from michigan, loving the trees. then he talked about the cars that he drove and the quote unquote cars that his wife drove, right? >> reporter: right, right. and the thing about that, i was in the room there at that football stadium where he gave that speech. and the message he was trying to send was, he and his wife, ann, really love cars. but i think the message that some people might have received is that they're really, really rich. so that's a problem for him. as you said, there's never a time where he does any huge damage to himself. it's just a bunch of little cuts and a lot of times it's about the way in which he sort of refers to things, the way he talks about things. truly a problem for mitt romney going forward, especially if he gets the nomination, because he's going to be up against a guy who tends to connect with

audiences when he has to. that would be barack obama. >> yeah, as we have seen before, joe, anything can happen in michigan and in arizona. joe johns, thank you. tuesday, two more opportunities for one of the republican presidential candidates to separate from the competition. our coverage of the arizona and michigan primaries begins at 6:00 eastern with a special edition of "john king usa" followed by live coverage of the results starting at 7:00 eastern. you know, the oscars are this weekend and one nominee could become the first african-american ever to win best documentary. his film about a high school football team rose to the top of the pack. ♪
