he said there are problems with the rescue efforts. >> there are many internationals coming to support a very gal lent and impressive local effort. relief items are coming in but the airport is quite con guests and limited in terms of capacity. so that has been a bit of an impediment. more importantly, what we have to do is get past kathmandu, and get to the epicenters of the earthquake. the rain has kicked in making a difficult situation even more severe. there will be a large contingent of people who will not be able to go back home because their houses were destroyed or are unsafe. and al jazeera's correspondent has more now from kathmandu. >> reporter: kathmandu international airport, the only way in or out of nepal since saturday's quake.

days only more or less. >> reporter: on the other side of the capitol, these are the lucky ones. they survived but haven't eaten for days until now. charities are stepping into the beach, lines of people displaced by saturday's quake are fed. it's their only source of food. they have lost everything. scenes like this are common across kathmandu. people continue to dig. many volunteers joining in the rescue and recovery operation, trying to find the remains of their homes or people buried under tons of rubble. back at the airport, planes are arriving all the time. it's working at full capacity. the authorities are giving the military priority to run across the quake zone and rescue survivors. help is coming in from abroad too, but the lack of space means only a certain number of planes can land.

with many roads badly damaged the airport is vital in the aid effort. the first few days after a quake are important to get rescue workers in to try to find survivors. police in saudi arabia have arrested more than 90 people suspected of belonging to the islamic state of iraq and the levant. let's go straight to mohamed vall who is in saudi arabia. what more can you tell us? >> reporter: according to the statement that was just released by the interior ministry and published on the saudi press agency, 93 people were arrested 65 of them saudis and the rest are foreigners. and these are according to the statement cells that are -- cells that belong to the movement of the isis the islamic state of iraq and the

clark. he was out here last night. what do you make of the reports that we're getting today that this is just a bunch of mindless criminal thugs on the streets. >> at the end of the day they were not mindless criminal thugs, they are lost youth, because they are not being educated. they are not being taught at home to believe in morals. it's the parent's fault for not telling their kids not to come out here. i did not see one parent getting their child. and that is not right. for them to have been out there peacefully at first and to feel threatened by the police that should say a lot about how people in this the city feel about the police. but it's like -- it's more to the -- everything that is going on. because we're not noticing how -- what the youth did, brought up a bigger picture to baltimore. >> reporter: what is that bigger

picture? again, this -- mindless thug that's the impression we're getting. but what is the background to why a kid would feel like burning up their own neighborhood frankly? >> they adopt -- don't know. i call them the lost youth. they are not being taught either in the education system or at home they are being taught by the streets. you awl talk about us as a whole. i'm talking about us as individuals. either you individual. you might look at me differently because of the color of my skin or because i'm a person but at the end of the day we have the chaos of all of these people and not look at the color of it. because it's not all the way our fault, but it's more though our fault, at the end of the day what we do. we're not going where they lay

at. we're going where we lay at. it -- it -- it should be more understanding of what we need to do to change the world. >> reporter: all right. corey thanks very much for joining us. there are those who then blame the kids for -- for burning up the city. there are others who say, look this is the symptom of something much deeper. this are areas that white baltimore, would quite frankly ignore. and perhaps it's a matter of dealing what underlay what we saw yesterday. back to you. still ahead on al jazeera, dancing to a different beat. vietnamese younger generations embrace economic prosperity. plus they survived a pair louse journey a lot the mediterranean sea, but what lies ahead for african migrants once they reach land. we'll report from sicily.
