says there's no plans to send troops - at least for now. >> we should be ready for all the circumstances. our forces are ready for the different threat. air or ground threat. there's no operation for the time being. if need we'll be ready to face this kind of threat. >> so far the strikes crippled the air force. the houthi response - defines. >> what do they expect us to do - surrender. announce our defeat. to act like cow wards. what do they expect collapse overnight, walk away - absolutely not. >> reporter: houthi fighters are not the only ones hit. about a dozen civilians were killed in the strikes. there were pictures of supporters in the streets of the

capital sana. they are not the only ones on the streets. yemen has been unstable for years. the houthis have been expanding their territory uds their base in the north. in january they force said the government outside of the government. last week this... ..bombing of two mosques in sanaa. it was not clear who was behind the attack but the hewitt yis responded. the president abd-rabbu mansour hadi is now in saudi arabia, and is recognised by the saudi arabia-led coalition and world powers as the legitimate leader. the alliance has ben doorsed by the nation -- been endorsed by the arab leg nations. the saudi-led intervention is seen in the region.

for the yemenis, hopes of a peaceful solution are dwindling the arab league is among those supporting the air strikes. egypt stated its support and participation. the military action was announced in a joined statement signed by saudi arabia bahrain and kuwait. jordan egypt and morocco say their planes have been involved in strikes. saddan said air and ground forces will take part. and turkey says it may provide logistical support. the pakistan government is sending a high level delegation including military officials to saudi arabia. let's get more from nicole johnson, joining us from islamabad. we know that pakistan has support for saudi arabia's military operation. in what way.

well so far saudi arabia has requested support from pakistan. pakistan said that it will consider that request. it held a high delegation meeting on wednesday with the president, the army chief and the head of the i.s.i. the spy agency. at the end of the meeting they said any threat to the integrity of saudi arabia would revoke a strong response from pakistan. pakistan has not said exactly what type of response it will be. they are sending a delegation to saudi arabia on friday to dougs action they may take. it's being considered. the defense minister gave a long and detailed interview. he was stronger than the statement and said that pakistan would be the first country to react if the integrity of saudi arabia is threatened and he

means houthi fighters crossing the border. >> we know there has been a lot of debate within pakistan as to whether the country should get involved. explain the concerns. >> pakistan has a delicate balancing act. on one hand pakistan has a good - a special relationship with saudi arabia. saudi arabia is usually the first country to help pakistan whenever it has a natural disaster. economic problems or an energy crisis. so a long history between the two countries. we have 8 houpz pakistani troops. they've been there for a long time. deployed across various areas and guarding the borders. earlier this month pakistan and saudi arabia asked pakistan to send more troops. on the other hand in terms of

pakistan's relationship with iran remembering the houthi fighters are backed pakistan shares a long border with iran the two countries has a good relationship. perhaps the main issue will be 20% of pakistan's population is shi'a. pakistan is concerned about not wanting to get too deeply embroiled in a conflict a regional war. it comes to be seen as a sunni shia war. we have a great deal of sectarian tension, violence and attacks, and the pakistani government would not want to escalate the situation by getting too deeply involved in yemen. >> thank you. nicole johnson there, pakistan's support for the saudi arabia military operation in yemen. >> syria's resident says he is open to dialogue with the united states. bashar al-assad made the

comments in a television interview with c.b.s. he said that there must be no pressuring of syria's sovereignty. >> in principle, in syria, we could say that every dialogue is a positive thing, and we'll be open to any dialogue with anyone including the united states, based on mutual respect. the united nations doubled its estimates of syrians living in we sieged areas. rights groups agree that the earlier estimate of 212,000 was too low. a 3-day lock down aimed at stopping the spread of ebola came into force in sierra leone. the president ordered etch to stay indoors friday morning until friday night. volunteers will go door to door.

sierra leone has been battling ebola killing more than 10,000 in west africa. airlines around the world, including easyjet and air canada an introducing rules requiring two members to be in the cockpit at all time after it was revealed the co-pilot of the germanwings plane was locked in the cockpit alone before crashing into the french alps piece by piece investigate pick through thousands of bits of wreckage. bits of wreckage unidentifiable nothing resembling a plane. some pieces are bagged up. yell aro markers -- yellow markers placed on largest objects. any human remains found of passengers and crew is treated with care.

families of some victims travelled to the accident investigation base and are here to see where their loved ones died and give d.n.a. samples to help identify the body parts. analysis from the black box has started to reveal the plane's final moments. listening to voice recordings from the plane, prosecutors say the pilot was locked out of the cockpit during the flight's final moments. the co-pilot apparently conscious was at the controls and appears to have deliberately crashed the plane. the passengers are heard screaming just before the final impact. >> the most likely interpretation we can make at this point is the co-pilot refused to open the door to the captain and activated the button triggering a loss of altitude. we do not know why, but it can

be interpreted as an attempt to crash the plane. little is known about andreas lubitz. he had over 600 fly experience and had no terrorist background. >> we are shocked and sad. in our worst nightmares we would never have imagined such a tragedy in our group. air bus, the makers of the a320 said there were situations when the crew entered the cockpit. seen here, an emergency access pin can open the door not if access is denied by the pilot inside. germany's parliament held a moment's silence. later the german chancellor angela merkel expressed her success. today's news is a blow to the relatives of the victims. in the dark days we think of

them. recovery teams will resume their work at sun rise. this disaster shook the aviation industry, and some airlines are changing procedures to make sure that two crew members are in the cockpit at all times, a rule that could have saved flight 9525 and its passengers the home of the co-pilot was searched by investigators, trying to find clues as to why he may have crashed the plane. officers were seen carrying evidence out of andreias lubitz home. and police searched his flat in dusseldorf. he joined germanwings after completing his flight course. he had flown 630 hours compared to the flight captain's 6,000 hours.

dominik cane has more. >> reporter: i'm standing outside the parents house of andreas lubitz who has been described as a decent young man, a man who liked jogging, into pop music, a member of the flying club and etch there and many in this community expressed shock and disbelief that someone considered to be a normal young man could have carried out such an act on board the airliner. a few hours ago the german chancellor angela merkel spoke of her disbelief and incomprehension that such a thing could happen. it touches a vain on the way this could be perceived. how everyone who has seen what happened said to themselves how could such a thing happen and everyone in jeremy is hoping crash investigators will be able to find out a bit more about what happened, but nothing could

change the fact that the man who lived in the house behind me is considered by the french prosecutors to be responsible for the crashing of that airliner. >> more to come on al jazeera. >> i don't currently know the specific goals and objectives of the saudi campaign. >> blunt answers to blunt questions in congress. how much did the u.s. know about saudi's intentions in yemen. plus... >> i'm rob mcbride, at korea's formula 1 circuit, trying to figure out a future without

formula 1. you're watching al jazeera. a reminder of the top stories. saudi arabia targeted sanaa in northern yemen. the houthis seized power in a coup last month. german police searched the family home and apartment of andreas lubitz believed to have crashed an airbus a 380 deliberately into the french alps. all on board were killed. a 3-day lockdown has come effect in sierra leone. the president ordered everyone to stay indoors from friday morning until sunday night. more on the saudi arabia-led air strikes. the u.s. is one of the nations supporting the operation.

there are questions about the extent of america's involvement. white house correspondent patty culhane reports. >> reporter: within hours of the air strikes u.s. officials came out to voice support, promising logistics and intelligence help. the congress opened questions about how much the u.s. is involved. the top general in the region admitted the saudis informed him before the first guns fell. >> isn't that a commentary on our relationship with saudi arabia and the other 13 in the coalition, that they would literally the day of their attacks, they tell you that the united states of america is going to launch a major campaign. i mean that is really a fantastic indicator of the deterioration of the trust and confidence that the countries, particularly saudi arabia has in us. >> the general couldn't answer a question. >> what is your assessment of

the likelihood of success? >> in yemen? >> yes. >> again, i don't currently know the specific goals and objectives of the saudi arabia campaign, and i would have to know that to assess the likelihood of success. >> analysts say from the u.s. perspective the definition of success is simply. the u.s. would like to see stability, but are not willing to pay any price for it. letting the saudis do it enables us to achieve goals without us being involved. >> the u.s. is considering sending saudi tanker and radar planes. for now the u.s. cibz is advice and public support. >> campaigning is winding down. ahead of nigeria's presidential election. leading candidates are delivering the final message before the vote. opposition leader is challenging

jonathan goodluck for the leadership of africa's popular country and called on nigerians to come out on mass and vote to remove who he called the incumbent government from office. access to quality education will be among the issues let's look at the country's education system. it has the highest number of children out of school anywhere in the world. more than 10 million, and violence is the reason many can't attend school. in borno, it's thought a third of all schools have been detroited by the fighting and 15,000 students are enable to attend the classes. the majority of students are girls. less than two-thirds complete primary school fewer finishing primary school. nigeria invests less in

education than any other country in africa. with all that in mind people are demanding the government supply free schooling, we report from where the government is trying to improve the education system. >> teachers say this 10-year-old is the brightest in her class. she has big dreams. >> i come here i want to teach people. >> the children attend a southern school. the governor is the man largely credited for trying to improve the accreditation system. >> it's a state of emergency. we started to build new schools. we train the teachers. many are not trained. when they come on board instead of training we recruited 250 teachers. >> education is free and

compulsory. officials say textbook and school uniforms are provided by the government at no cost. >> children wear the same uniform. doesn't matter whether you are from a rich or poor family. >> facilities in several goughs was across nigeria, and things in river valley are not good. activists accuse politicians of having double standards. children are educated abroad. with our money, our resourceses, because they are in political power. that is untare yet the children of other ordinarily people the voters, are not able to attend the schools. >> precious attends a private school. tuition is $1,000 a term. the 16-year-old says the government-run school can't give the opportunities she needs to get a head start in life.

>> we have here a library, physics. chemistry, biology. they are well equipped. it seems poorer schools are catching up. the facilities are better than most. >> the challenge for politicians is making sure every child has access to the best two the u.k.'s prime minister david cameron came out on top after a televised debate in a nationally fought election. topics included britain's involvement in libya's intervention and saw the end of the the regime. despite the crisis in libya, he did not regret englands membership of a mato led organisation. parents staged a rally after

up in the family vehicle, he's never had a driver's licence passport. his anarchist parents didn't register his birth. he wandered but settled recently to have a family. >> border agents showed up at my house, it was just me and the children. he came with an attitude that i wasn't canadian, that i'm an american. and i'm not. >> reporter: immigration threatened to deport him. he said he doesn't remember where he was born but lived here all his life. three heart attacks bought medical bells. people without documents are on their own. >> my dog has more rights than i do. i'm a nobody. in the eyes of the government.

i'm tired of being treated that way. my parents - my parents made the choice, i'm the one suffering for it. he appealed to the minister to use discretionary power to grant canadian nationality. one of the ironies is it happened in dawson city a place that was not clearly defined as being part of the u.s. or british ruled canada. during the gold rush this photo of a u.s. independence day crowd frightened ottawa in asserting canadian sovereignties. authorities today seem in no rush to address this issue. >> citizenship is framed in the refugee or immigrants or skilled immigrants. those classes are getting more

attention. and citizenship in general for those that don't have it - it's not a priority. >> donovan and his family await the canadian government's decision, and hopes soon he may call it his government get a birth certificate and timely be a citizen of somewhere in south korea debate is intensifying over the cost of the winter olympics. the 2018 games carries a price tag of 12 billion. after the experience of previous sporting investments some are asking if it's worth it. >> it is the world class circuit that was supposed to put south korea on the formula 1 racing map. after just four grand prix's the racing world forgot that it is here. unable to generate the local support or the revenue needed to keep formula 1 here, the race

track operators have been looking for other events the operators nist the circuit should not be viewed in dollars and cents. >> a facility like this should be seen as a social investment instead of a business having to earn revenue. the federal government is not as popular and the government does not feel it is responsible to sponsor us. at the root of the problem is planning. located in the remote south of a country that has limited interest in motor sports. critics say a lack of foresight seems to be a national failing. >> when it comes to planning you have to look at how to make these venues or the surrounding towns as a preferred or favourite destination places as opposed to a single venue. but i'm not sure if we have done a good job of planning that way.

>> south korea's third city has enough people. such was the scale of the 2014 games it hosted last september, it is tackling the problem of finding new uses for the facilities and is deeply in debt. >> it has high hopes that it main stadium will find a new use, but admits it could take years and nose the country is watching as south korea prepares for its next sporting feet. >> construction is advance said for the 2018 winter olympics. so is the debate over cost and future use of the site. at least the debate is happening now, rather than after the event. >> the biggest lesson is an opportunity for everyone to get involved in the planning stage and the dialogue has begun. >> the operators say the olympics like formula 1 will

encourage the growth of interest to fill the facilities. a strategy of if you build it they will come. experiences showed they may be a long time in coming and you can get more on our website at aljazeera.com. it's one of the toughest jobs in america now, ferguson, missouri's new acting police chief - speaks for the first time on national television to this show about fixing what is broken, and of the fear his companies face on the streets. >> they are afraid. if you are sitting looking in the crowd, it's in your mind who has got the gun. and there's no way to prevent it.
