this is al jazeera live from new york city, i'm stephanie sy. we begin with new accusations about the use of banned drugs in american professional sports. according to media reports, the nfl and mlb say they will investigate questions of doping raised in an al jazeera investigative documentary, the dark side, secrets of the sports dopers. al jazeera's investigative unit infiltrated the world of sports doping with the help of liam clubs, a british athlete that recorded hours of conversations with doctors and a pharmacist who made astounding claims about specific professional baseball and football players, claims the players deny. deborah davies has a preview. >> on hidden camera footage, a pharmacist in texas, charlie sly advises british cleat liam collins on the use of drugs banned in professional sport.

>> one anabolic, i can give you something to use right now is this delta two stuff. it is a steroid. >> it will be great for you. >> there's a bunch of football players who take this and baseball players, too. >> liam collins isn't a drug cheat. he's working undercover for al jazeera's investigative unit to exposed what athletes call the dark side, the alleged i see of performance enhancing substances. charlie sly claimed connections to several top sportsmen in american football and baseball. one player, taylor teagarden was filmed in sly's apartment discussing his own use of the delta two drug. i used it last year, i was scared to be honest with you. i took it for like two weeks and i was also taking peptides, too. >> sly alleges that when he worked at an anti aging clinic,

the guyer institute, a banned substance was shipped to the wife of football star peyton manning. >> we shipped it to her. >> it's complete trash, garbage, there's some more adjectives i'd like to be able to use, but it really makes me sick. we spoke to the guyer institute. he gave us the start date char lie sly worked in 2011. in the last few hours, sly issued his own video denial. our investigation also infiltrated a doping network in canada. we filmed a pharmacist and doctor who flied our undercover athlete an array of banned drugs and offered to destroy medical records to cover it up.

>> there was no response to request for comment. other athletes who did respond deny the allegations. al jazeera's undercover investigation raises new questions about the possible use of performance enhancing drug in sport. as you just saw in deborah's report, peyton manning is the highest profile star named in this investigation. in 2011, he was trying to recover from a neck injury he suffered as the quarterback of the else coats. for the past four seasons, he has been with the denver broncos. he is now one victory shy of setting the nfl record for wins by a starting quarterback. manning has mounted an aggressive campaign against the

al jazeera report. here is more of his interview sunday on espn. >> makes me sick that it brings ashley do it, her medical history, her medical privacy being violated. that makes me sick. i don't understand that, and, you know, i'm in the middle of my throwing workout which i enjoy doing that and i've got to interrupt this workout to come and talk about this. it's not right. i don't understand it. >> have you ever used h.d.h. or any performance enhancing drug? >> absolutely not. absolutely not. what hurts me the most about this is whoever this guy is, this slapstick trying to insinuate that in 2011 when i, you know, more or less had a broken neck, i don't know, four neck surgeries, broken neck, i'm sure there's a different in there, but i had a bad neck and i busted my butt to get healthy, put in a lot of hard work. i saw a lot of doctors.

i went to the guyer clinic. he had a hyper parric chamber that my coach and doctors thought might be good for me. they went with me and thought it might help. i don't know if it helped. didn't hurt. time ended up being probably my best medicine along with a lot of hard work and that really stings me, whoever this guy is insinuating that i cut corners, i broke nfl rules to get healthy. it's a joke. it's a freaking joke. >> the reporter on the sports doping documentary earlier on your world this morning we asked her about the main witness who is now recan'ting what he said. we approached liam to work with us. we guided him through every single step of the investigation. if you say someone has recanted, that implies they've made a statement for one reason or another changed their mind. that's not what happened here.

we filmed with charlie sly over six days two or three meetings a day, hour upon hour upon hour of footage. every time we met him, we reviewed the footage, we primed liam with new questions to get more details about what charlie sly was saying. we contacted him three weeks before the program went out by email, by letter, by phone to ask him if he wanted to comment. he said nothing. suddenly, 48 hours before the program's due to air, he comes out with a statement saying i've recanted, so one of the whole reasons, the justification for secret filming is that people with things to hide will speak openly in a way that they won't if they think they're actually going to get found out, so you just have to make a call, is he being truthful in those hour upon hour upon hour of filming, is he being truthful when he's on the edge of being exposed, you can decide. >> this is stephanie, good morning. peyton manning as you know has hired former white house

spokesman, ari fleischer. fleischer confirmed that manning's wife was also a patient at the center. i wonder if you investigated whether she was taking growth hormone. sometimes doctors prescribe off label for anti-aging. >> of course we've explored it. this is really eight months of rigorous journalism that's resulted in this program. we've asked the question and it hasn't been answered. when you say the growth hormone is used, if it is used in that way, it is illegal. let me make it really clear, growth hormone is one of the very few drugs that you cannot use off label. there is federal law saying that growth hormone can only be prescribed for three incredibly serious conditions for cancer or something similar. a story of potentially

manning's wife ashley taking off label use of growth hormone is very different than the implication that peyton manning himself took growth hormone. >> then they should answer the questions we've asked. those are precisely the questions, the allegations in the program from charlie sly is very clear that growth hormone was shipped by the guyer clinic to ashley manning in florida. until they answer the question who was it shipped to, who was it taking and for what condition, this story is going to keep rolling without any clear acknowledges. >> guyer institute says that charles sly was an intern there in 2013 for three months but he wasn't there in 2011. do you have documentation to the contrary? >> i do. i rang the clinic on the first of december. i said i was doing a verification check for charles sly. they put me through to someone

who said oh, yes, she immediately recognized his name. she went and got the records. she came back and she gave me a precise start date for him in 2011. we have a full transcript of that conversation. i don't know if he was there in 2013, i do know that the guyer told us he was there in 2011. >> the al jazeera investigation providing nfl commentators and analysts with plenty to talk about on sunday. >> al jazeera's investigation into questions of sports doping is sparking swift reaction from nfl circles. >> i've never seen peyton any angrier. >> these former athletes, now espn analysts are standing by denver broncos quarterback, peyton manning. >> he said he didn't do it. if he said he didn't do it and it didn't happen, it didn't happen and he didn't do it. that's it, end of it. >> you hate that it gets legitimized as a story at all.

>> the broncos said in a statement: >> manning's former team, the indianapolis colts, writes: >> the quarterback hired ari fleischer as part of his p.r. team. he told the denver post there's no truth to it. manning's former coach dungee defends the quarterback. >> it's not the former peyton manning i know. he has too much respect for his legacy, for the game, what it means. i think he would do everything in his power to get well but i do not believe he would go outside the rules. >> gary brackett writes on twitter:

>> the leagues is not commenting on the documentary, but the bleacher report cites sources saying the nfl will investigate claims about the athletes named in the documentary. al jazeera. >> you can see the full documentary al jazeera investigates, the dark side, secrets of the sports dopers today at 3:00 p.m. eastern, noon pacific. evacuating syria, a rare u.n. booked deal allows fighters and their families to leave parts of the country. how a plan aimed at stopping attacks against the u.s. is creating new problems for the iran nuclear deal.

in afghanistan, a suicide bomber set off a car full of explosives next to this pickup truck. the attack happened on a road near kabul airport. the targets were nato security forces. evacuations have been going on for hours today in syria. more than 400 wounded fighters and civilians are being evacuated from three war-torn syrian towns. this is part of a u.n. backed truce again the assad regime and rebels reached in december. it calls for fighters and civilians to be moved from one part of syria to another. we have more on the evacuations from turkey.

>> the deal between the syrian government and the rebel faction groups is quite significant. it is going to pave the way for 100 and so syrian rebel groups to be evacuated to across into lebanon and be flown to turkey where the injured are going to be treated. then it remains to be seen whether most of those fighters are going to be relocated to refugee camps on the border with syria or they're going to cross into areas under control of the rebels. in exchange, we are going to see pro government militias, shia militias, crossing into, given safe passage crossing into turkey and flown to beirut. from beirut they will drive to damascus. it's a very important development. it comes against the backdrop against the international push

to find a political way out of syria. in geneva they will meet in the next month to find a solution to the crisis and put an end to the killing of thousands of civilians. reporting from turkey. >> in iraq, the army is in full control of the battleground city of ramadi. sunday, iraqi troops were seen hoisting flags and celebrating. forces have also cleared the government center. ramadi, a predominantly sunni arab city fell to isil in may, a major setback in the country's efforts to contain the group. the u.s. is trying to verify an audio of isil leader abu bakr al-baghdadi. he pledged future attacks against israel and the west. new visa rules are creating

hold dual nationality with those four countries, even if they've never set foot in their parents' homeland. >> if your father is an iranian national, you are considered an iranian national and that applies even if you have never traveled to iran, but that is the circumstance that a lot of people are now going to be faced with. >> the law sparked an on line campaign condemning when the opponents call a creation of second class u.s. citizenship based on national origin. the european union, most members don't currently need visas. its ambassador to washington warned that european countries would have to retaliate against american visitors, only hurting the economies on both sides of the atlantic. the motivation appear clear to iran. the speaker of its parliament said they were aimed at harassment and blatantly violate the nuclear agreement by sabotaging iran's efforts to recover from years of economic sanctions. the obama administration is worried about the visa changes. >> it could have a very negative

impact on the deal. >> john kerry assured the iranians the visa reform would not be an obstacle. he said the american administration have the power to wave the rules so not to interfere with the business interests of iran. >> those who oppose the nuclear deal say they will resist any effort to placate iran, but after realizing the unintended consequences of the new restrictions, some of their leaders say they may have to reassess next year. al jazeera, washington. parents worried about their children's safety in the u.s. how muslim families are dealing with rising backlash against the country. parts of the southwest are hit with tornadoes and ice, the latest on where these storms are heading, next.

that is they be going to go into the panhandle of florida. so far this morning, we have seen quite a bit in terms of wind damage. all of those yellow dots which means winds 50, 60, even 70-mile per hour winds there, as well as tornadoes reported in parts of mississippi. these are the warnings that have just come out and been updated. you can see over toward the panhandle of florida and alabama, those are tornado warnings. this area is going to continue to make its way toward the east where that line of thunderstorms we'll probably see these warnings go into parts of george. >> later on this afternoon, as well. otherwise, we are also talking about that snow system moving towards the north. we expect to see quite a bit of snow out of this as well as on the warm side, a lot of rain flooding and flash flooding. you can see the areas of flash flooding which have been expanded over the last several hours down toward the mississippi river and parts of oklahoma. then of course, the big problem

coming into this afternoon and evening is going to be the icing. we expect to see half an inch to possibly up to an inch of ice in parties of illinois, as well as iowa. >> not a pretty picture in a big chunk of the country. in houston, a fire that broke out as a mosque on christmas was intentional. the houston fire department said the fire at islamic society of greater houston was not accidental, and natural causes have been ruled out. federal and local authorities are now investigating the fire as a potential hate crime. there have been a rise in attacks on mosques since the mass shootings in california and paris. those attacked a to the worry of parents who send they are children to school locate inside mosques. we spoke with american muslim parents and chin dealing with new tensions here in the u.s. >> america the free, marvelous place to be, endless education

>> i have an issue with the term moderate muslim. the san bernardino attack, right, if you look at the characteristics of how that person is described, so somebody who went for pilgrimage in 2013, who came back with facial hair, we look at that and we're like oh, crap, that fits my characteristics. >> it's exhausting to be constantly trying to explain or trying to be a model of your faith because you know that the majority of people don't understand it. >> hermela aregawi, al jazeera, new york. thanks for watching. you can see the full documentary al jazeera investigates the dark side, secrets of the sports dopers today at 3:00 p.m. eastern, noon pacific.
