science. and it all just meshes right together. and it builds your case. but without that, you know, we'd still be back in the dark ages of investigating crime. flight 5935, profile of andre i can't say lube its. arab leaders, new leaders show a saudi convoy headed to yemen, plus, the funeral for singapore's founding father. hello and welcome to viewers around the united states and around the world. you are watching cnn news room. let's start in germany.

investigators say a doctor declared him unfit for work. they suggest the co-pilot suggested of downing the germanwings airplane may have had a troubled past. an official with knowledge of the investigation. police found antidepressants in the home of andre i can't say lubitz. fred is live from germany with the latest and following the story for us. good morning, fred. yesterday, we declared he was unfit for work by doctors. now reports of antidepressants, what do we know? >> reporter: there's a lot of reports coming in, a lot of allegations. we have to sift through what we can say and what is not clear. a big newspaper here in in germ

any says when police search a home he lives in there there were a lot of drugs there. he was suffering from burnout syndrome. "the new york times" saying large amounts of antidepressants were found in the apartment he stays in. we know from the public prosecutor, he was deemed unfit to work by a doctor who had been seeing him for a considerable amount of time and also several sick notes were found in one of the places that he lived as well that were torn up in an attempt to hide an illness from his employer. "the new york times" was saying two sources confirmed to them, he was suffering an i illness. we are were not able to verify that. we were in touch and he

acknowledged he came to him for diagnosis twice this year. it was not related to depression. they did not say what it was related to. in all of this, we got in touch with his employer, luft than sa and germanwings. they would have found out if something was wrong with his eyes. there was no indication he was suffering from depression or another form of mental problem. if he was and if he was seeing a doctor, he would have been obligated to tell them. >> yeah, he would have been obligated to tell them, that's the crucial part. he passed his exams, did they have a psychological exam and what would that be like? >> reporter: it's a very good question and the answer to that is they don't. the medical exams, they don't have a psychological part to them. they don't have specific

psychological evaluations. the way this works is is a lot of it hinges on self-reporting. they have to report psychological or medical problems. he didn't do that. when the pilots are cadets or training to be pilots, there are psychological evaluations. the entire process of becoming a pilot means putting them under stress and seeing how they function under duress situations. he clearly passed, but something happened along the way he didn't tell his employer about. fred for us in germany. thanks, fred. we are hearing this morning for the first time how the family of andreas lubitz is

reacting. they carry the weight of the tragedy. the mayor said it hurt him to see him expressing his emotions as he lost a loved one, but his son may be the reason for this tragedy. in a village near where the scene went down, mourners held a service. loved ones and people living nearby have been gathering to pay respect. aaron mclaughlin joins me now where the flight kratched in the alps. erin, bring us up to date on the road being built around the crash site. >> reporter: hi. hi, that's right. they are looking into building a road to the crash site to allow vehicles to access the site and take part in the recovery area and give access to the families

so they can one day be able to come to visit the crash site to mourn the loss of their loved ones. recovery teams say they are making good progress. there are two choppers in the sky today. some 400 people have been mobilized as a part of the recovery effort. hundreds of police officers, firefighters, mountaineering suspects from spain and germany. yesterday, we spoke to a pilot taking part in it. he described the conditions and what it was like to fly over the area. take a listen. >> we can't imagine it was a very big plane, a 320. when we were coming, flying over the place, you can see millions of little pieces of the airplane. we can't recognize anything. >> reporter: he said he was proud to take part in this

operation. he felt it was his duty to help bring the human remains back, to help give the families closure. yesterday, i was talking to the spokesperson of this operation and i asked him, emotionally, how are the workers coping with the realities of the crash site, the grim, cemetery-like scene there. he says they are coping as best they can. he said they are professionals, they are used to dealing with tragedy. should they feel the need to talk to someone, a psychologist is on hand here as well. >> erin, thanks very much. we'll bring you all the latest developments on the plane crash in the alps. you can stay updated online at cnn.com/germanwings. in singapore, people are paying respects. the founder and prime minister at a state funeral. a few people have taken the

take you to switzerland. talks to reach a framework deal with iran have resumed. cnn's global affairs correspondent says iran is refusing to budge on two issues. >> reporter: a lot going into the nuclear talks. now, they have hit a snag. diplomats saying iran is playing hardball on two key sticking points. one, the advanced technology, research and development program iran wants to maintain while the deal is in effect. the international community trying to put tighter limits on the program iran is looking for and on sanctions. iran wants to get the sanctions lifted on day one of the deal.

the international community, particularly the united states wants to phase those sanctions out. the german and french foreign minister arrived saturday meeting with the secretary of state john kerry. the british, the russian and the chinese expected this weekend, try to make a final push for a deal ahead of the march 31st deadline. now, they could go on a little bit longer, but there's a lot of pressure in iran to show it has a pathway to get the sanctions lifted. for the obama administration, they need to show something so congress to pass sanctions that could scuttle the deal entirely. the question is, has each side met its red line? the international community says iran needs to make tough decisions. iran's foreign minister wants a deal, but it has to work for them. >> in iraq, u.s.-led coalition

air strikes continue to hit targets around tikrit as they try to retake the city from isis. we h have the report from the vy front line. >> there's movement in the house he's seeing. >> reporter: this is tikrit's southern border. a number of positions along the shoreline. they are trying to add vansz. inside the city, hundreds of isis fighters fortified in buildings, underground tunnels, booby trapped roads. they were all isis positions. for weeks, iraqi ground units were unable to push into the city. the government requested air strikes from the u.s.-led coalition. by saturday, two days after the coalition started bombing, bullet casings littered the roof. jets flew overhead.

24 hours ago, we would have seen isis holding positions on the very outskirts of tikrit. because of the air strikes and heavy artillery, the isis fighters have been pushed further back, at this stage. america says precondition for coalition bombing. the umbrella group made up of shia militia and volunteers would pull back and not be a part of the final phase to liberate the city. nut sg that straight forward here. they have not withdrawn from any areas of responsibility. the general and police commander on the ground said the base we are at is a hashed base. we hope that in the coming days, all the units holding the ground will enter tikrit, a unit second

in command. these are iraqi rockets, he says. everyone quickly turns to see the impact. arwa damon, cnn, tikrit, iraq. >> they are meeting in egypt and expected to announce road security threats in yemen. the final from the weekend summit will demand fighters leave the capital. there's a new envoy headed toward yemen, suggesting ground troops could be entering the area. we are live where the summit continues. ian, good to see you. let me start with what's circulating at the arab league summit. what does it say? >> reporter: this ground invasion almost seems all but certain according to it.

they are signing up to support the retaking of yemen by air, sea and ground forces, if necessary. we have nine countries sign up that they are willing to go in and participate in a ground invasion. saudi tanks heading to the border with yemen. there has been talk that this ground invasion could happen within days. that coming from the foreign minister talking to becky anderson last night. >> i think we need the ground troops to keep things together. >> you are talking days? >> could be. >> reporter: and this conference, the summit has endorsed the saudi plan of action in yemen. it hasn't been unanimous. there are countries decenting,

including iraq and lebanon. they are shiite majority countries. they oppose the operation inside yemen. they believe a political solution is still available. this is something that they could achieve. really, it looks like, at this point that that ground invasion could happen soon. >> you said it could happen within days. are they saying how long it would last? saudi arabia talking on that? >> reporter: really, if they do get involved in this ground invasion in yemen, their objectives, they stated, saudi stated they won't leave until they destroy their capabilities of waging war. that could take a long time. they are adepth and fighting gorilla-type wars. they have been in control for awhile. they have been able to prepare

for this. it would be, potentially, a bloody battle and difficult and long one if the ground invasion does, in fact, move forward. egypt fought a ground invasion in the 1960s. they consider it their vietnam. they committed up to 40,000 troops and had fatality rates of between 5,000 and 10,000 soldiers killed in that conflict. expect, if a ground invasion does go forward, it will not be quick and it will be bloody. >> absolutely, the situation on the ground is escalating. we have likes of unicef warning of a major humanitarian crisis. it is about 20 minutes past 10:00 in the morning. thanks. a new law in u.s. state is spiking backlash from the ceo of apple. we will show you what is in the bill that is causing such a fire storm.

welcome back to cnn news room. a commuter train crashed in los angeles. it was near the university of southern california campus on saturday morning. the car turned on to the tracks as the train approached.

the 21-year-old driver is in grave condition. a police on america's top cops is in a coma after being shot in the face in the u.s. state of massachusetts. the officer was shot during a traffic stop in boston on friday night. he remains in critical condition. he was one of several officers who helped save a transit officer wounded in a gunfight with the boston marathon bombers. the state's passage of religious freedom is so controversy even the white house spoke out against it. we have the law and the reaction. >> the signing of this bill doesn't seem like it's a step in the direction of equality and justice for all americans. >> the indiana governor signed this bill into law thursday drawing businesses, politicians

and religious leaders. >> this legislation is ugly, mean spirited and intended for harm. >> the law says the government can't ban their exercise of religion. those who feel their beliefs have been burdened can lean on this law to fend off lawsuits. while the law does not mention sexual orientation it can be against lesbian, gay, transgender individuals. he rejects that claim. >> this bill is not about discrimination. if i thought it legalized discrimination, i would have vetoed it. >> reporter: he says the bill sends the wrong signal. indiana is a welcoming place that attracts businesses and residents. we are a diverse city. i want everyone to feel

comfortable here. many companies aren't pleased either. apple ceo said we strive to treat every customer the same, regardless of where they come from. ang angie's list canceled and expansion project. they were due to break ground in days. businesses across indiana are participating in the open for service campaign posting stickers and clients they are not subject to discrimination. i'm andy rose reporting. an air canada flight skidded off the runway. the plane made a hard landing as it arrived from toronto. our partner reports 23 people were sent to the hospital with minor injuries. the airport will remain closed for a few hours for clean up. another cold snap settled in

the eastern half of the united states. eric joins us with the details. just how could are we talking here? >> this is not a happy weatherman. i did my first attempt of gardening in atlanta where we are located. i have my lettuce, peppers, chilies and i wake up to freezing temperatures. not good news for anyone who is going at their first attempts of planting a garden. this is stretching across the mid-atlantic states and the east coast from atlanta up to new york city. the only solace i have is i am not alone. this picture was taken of boston harbor by an i-reporter. just now, the ice is starting to break up in the harbor. that is unbelievable. we are talking the end of march. april is in sight. we should be warmer than this. this is the temperatures they

will be feeling on the skin when we factor in the wind. we are talking single digits from buffalo, new york to state college, philadelphia, new york and providence in the teens and lower 20s. a very frigid start to your sunday morning and weekend. the cold snap of air in terms of temperatures, we are expecting 10 to 20 degrees below normal. on the contrast, a tale of two seasons, the western half of the united states, temperatures ten to 20 degrees above normal. that includes, colorado all the way to california where we have had extreme heat lately. we'll talk about that in a moment. i want to show you the forecast we are expecting over the east coast in terms of precipitation going forward to the start of the workweek. monday, that is white. a shading of white over the nation's capitol and the new york area. snowfall, we have a possibility of a rain/snow mix with

thunderstorms across georgia where cnn is located. cold weather continues to inundate the coastline into the first parts of next week. you can see the warmth continuing, stretching over los angeles. this is the forecast we have. i want to take this heat and bring it to the east coast to help out my friends in boston and d.c. phoenix, just shy of 100 degrees. this is going to melt a lot of snow across the ski and snow hills and mountains across the colorado rockies. not good news for skiers and snow borders out there. back to you. >> you want the weather not just for your friends, but to help your harvest. very important. >> it is important. i need this. >> derek, thank you very much. >> thank you. you are watching cnn news room. a pilot who flew with the man who suspected the downed german flight and what he said.

the captain was identified and visited the makeshift memorial. search crews are looking for the missing flight data recorder and the recovery of those who died. nic robertson has more on this. >> reporter: each day begins here. helicopters lifting off. local rescue pilot david among them. friday, particularly tough. >> the wind was always turning inside. sometimes this way, sometimes this way. for us, it was very difficult. we are always in very, very close limits. >> reporter: lives are in his hands bringing recovery teams to the crash site. >> we are in a closed area, very, very closed from the mountains. it's a very short place.

it's quite difficult for us. >> reporter: as the team makes the gruesome discoveries, he comes back, lifting, swinging them homeward. >> i don't want to focus on the possible victims i see on the floor. so, i know i will bring back bodies to the family and i think it's very important, it's my duty. >> reporter: from the mountains, the bodies are brought here to a mobile forensic's lab for dna testing. all of this happening in a remote and small alpine village. here, they have opened their hearts, touched by the tragedy unfolding around them. people at the nearby building gathering at the memorial for the crash victims. david, the helicopter pilot and the community are still in shock. >> we can't imagine it was a

very big plane, you are flying over the place. you can see millions of little pieces of the airplane. we can't recognize anything. >> reporter: each day ends with a helicopter's safe return. normality for everyone here. still a long way off. nic robertson, cnn, france. >> investigators are talking to andreas lubitz friends and former girlfriend. she said lubitz would dream the plane was crashing. john, thank you for taking time to speak to us. let me ask you this. who, exactly, is this former girlfriend and when did you speak to her? >> i spoke to her on friday.

actually, it was when i got in touch with her. it was a tough meeting. she's shocked after the incident. she never expected him to do something tragic. actually, what was the second question, again? >> exactly who is she? who is this former girlfriend? >> okay. she is the age of 26 and works as a flight attendant. they got to know on the flight more than one year ago. it was like they feel comfortable with each other and started a relationship. they kept it secret because she was worried that maybe this relationship could affect her career. this relationship lasted for five months, after that, she broke up. >> right. let me get this straight. they were together, she was a

flight attendant, they kept the relationship secret. they were together for five months. how long ago was this? >> this was like more than one year ago. >> right. let me ask you this, what does she say? did she see signs, telltale signs of reports we are hearing about his health? >> you know, there was one remark she quoted, she also mentioned one year ago. it was one day i would do something that will change the whole system, then all will know my name and remember it. according to her, he was, during the relationship unhappy with his job situation. he realized his dreams of becoming a captain of an airplane, a long-term contract with lufthansa may not come true

because of his mental illness, you know. and, actually she mentioned that one day family woke up in the night after suffering from a nightmare and screamed we are going down. maybe after all this was maybe one clue that led to the tragic incident. another night, he locked himself in the bathroom for a while without any explanation. she mentioned that, you know, there were two sides of this person. get among people, she told me, then he was open minded. if there were on their own, he actually turned into a different person. sometimes aggressive shouting at

her especially when they discussed working conditions at the company. >> john, did she speak -- did lubitz speak openly to her? how did he explain the dreams? did he speak openly about his condition? >> reporter: not really. she mentioned, i asked her a lot about that. she mentioned that he spoke in a short sequence about problems. he told her that he used to go for medical treatment to get help but he didn't get too much into detail. you know, after an incident like nightmare, she asked him what's

happening? what was your problem? you know, then he didn't commend it at all. is that the reason why it led to the end of the relationship. she told me, in the end, she wasn't strong enough to be there for him and his problems. she wanted to smile again, have a good life again. that's the reason why she ended the relationship. now, she's shocked about what happened. >> did she ever notice whether he was taking medication during the time they were together, john? >> reporter: no. actually not. she didn't mention anything about that. you have to imagine it like that. according to her, they had a relationship. she was flight attendant, he was pilot. they didn't stay together permanently. they met for different dates.

so, maybe for one night, maybe for a couple hours. so, i ask her that and she said she never noticed that he took pills. but, she was -- it appears she was kind of -- she's a really open, honest person who can listen carefully to your problems and give you good advice. it seems like he opened to this person and she gave him advice how to react and calmed him down when he actually turned out. had faith in her surroundings according to her words. maybe proof of that is he was running for her after she broke up. >> finally, john, let me ask you this. there were together for five months. did she break up the relationship because she feared for his mental health or her own

sanity, really? >> reporter: no, no, that's not true. like, she -- because of his medical problem. it was like she was frightened after incident of shouting at her. incidents like that. said she felt pressure. that may be more -- she was dreaming about a perfect relationship, you know, where someone is equal to her. she didn't feel that anymore after five months. >> all right. john is a bild reporter who interviewed the former girlfriend of lubitz, the

co-pilot. thank you for taking time to speak to us this morning. you have seen a lot of folks in the pilot's care and their mental health. i want to get to christianuates joining us live by skype in england. i wasn't sure whether you managed to hear the interview with the journalist who interviewed the former girlfriend. if you did, i want to get your reaction on his mental health from what you heard there. >> you know, the mental health issue is prevalent at the moment. there are issues with regard to mental health. i think we need to be very careful as to how we debate such subjects going forward. >> yeah, absolutely, you are spot on about that. we are being extremely careful. this is one person's account,

his former girlfriend. it's just one threat of this whole story. let me ask you this, there are many, many stories whachlt you heard from authorities, what has stood out to you? >> well, two thing that is really stand out. the lack of psychometric testing amongst pilots. that's an issue that has been there for some considerable time now. it's an issue that we need to address as quickly as possible. also, the issue of securing the cockpit door. it should never be the case that the cockpit could be sealed off completely. there has to be some method of override to that that would

allow another person to gain access in the event of that emergency we saw three, four days ago. >> i want to stay with the mental health, if you don't mind. i was speaking to a former pilot on the show here yesterday. he said he has been in the cockpit with pilots, he's seen them cry due to stress, personal reasons. he told me, none of them would ever report anything to the airlines because no one ever thought anything like this could happen. do you think the relationship between pilots and co-pilots will have to change because of this? there will need to be reporting and assessment by pilots and co-pilots? >> i think there's got to be a culture of reporting, if you see something as a pilot or co-pilot. if you see something that is worrying to you, in terms of

behavior of colleague. there has to be that formal reporting process that goes on. but, i have to tell you, in this day and age, it's not necessarily the case that does go on. it used to, with an airlines, but nowadays, there's a lot of fear over job security and other thing that is prevent that from happening. >> yeah. absolutely. it's a very, very good point there. chris yates. thank you for your insight on cnn news room. you are watching cnn. we'll have much more news after a short break. all we need to do now is just put our platter in the oven which we've already prep- hold on, sharon! you can't cook that sea bass in a greasy oven. why not?

to bid farewell. he had been battling illness, admitted to the hospital with pneumonia on monday and sadly, or i should say last month and passed away on monday. he will be remembered for taking singapore from what was a third world country to a first world country, to making it this major economic powerhouse, really the envy of so many other countries. in regions, southeast asia where there's instability and corruption. he produced a country that was seen to not be corrupt, to have great governance, to attract foreign investment, to be a country where, you know, people had incredible wealth, well educated, really was, i guess, the exception to the rule in that part of the world. he was considered a visionary, not just by singapore but other

leaders around the world. this is a man who really was the driving force behind the country. he was the prime minister for more than 31 years. he did, however, have his criti critics. they say he was athor tear yan. when critics called singapore a nany state, he relished in that. he said that is what made singapore great. you have to see the outpouring of emotion that we have witnessed this week. his body has stayed in parliament house and people were lining up for six to eight hours just to pass by and pay their e respec respects. same goes today, people standing in the pouring rain to bid farewell. as you say, world leaders from all over the globe gathered at the national university of
