. in afghanistan rescuers have abandoned a search for those in a mud slide. hundreds of homes were buried. more than 2,000 are missing, feared dead. it occurred in badakhshan. that remoteness made it difficult for aid agencies to reach the affected village. we have this report. >> reporter: mass prayer for a mass grave. these african villages have given up on survivors of the landslide. now they want to locate bodies. a focus has moved to helping hundreds of people who lost their homes. >> translation: i'm one of the survivors that came out of the mud. right now we need tents so we can be sheltered from the rain. around 700 houses are under

threat of landslide. there are four valleys, water can flow into here. if water flows in, the village will be under water. >> digging continues to find thousands under the mud >> translation: seven members of my family were here. four or five were killed here. i'm half alive. what can i do? >> days of rain caused the side of this mountain to collapse. mud and rocks swept into the village below, destroying everything in its way. hundreds of homes were buried, many people inside. volunteers of nearby villages came to the remote area with tools and shovels to help rescuers. >> we have been bringing blankets, household items, solo land earns and a number of ngos in u.n. agencies bringing items such as tents, food, hygiene

supplies and so forth. >> it's been hard for emergency teams to reach the site. the narrow roads have been damaged by rain and can't take the heavy machinery typically used in recovery efforts. the hillside remains unstable adding to fears another part may cave in. >> a team has arrived in the disaster area, and we have this update from there. >> villages tells me that aid has come. it is temporary aid. for now the aid is not organised. it is not distributed properly. they want more transparency in terms of delivering aid to the needy people, to the people who basically have suffered or survived this massive land slide. getting the aid to this area has been a changing task for the government or aid organizations. the roads are watched out by the

floods in the past week. the mountains, the geography is challenging to get all the aid required on time to these people. joining me on the line from badakhshan is matt gray don, working for an aid group that reached the area - sorry, is it abby. >> yes, i am. we are outside the village where the landslide took place. >> what is it that you are seeing, and how far you are as far as getting bodies from the ground is concerned? >> we can see the devastation caused. the entire mountainside washed away. it's remarkable. where we are now, hundreds of families are looking for sps, and there are a lot of -- assistance and a lot of people have lost almost everything. >> and what about those missing

now. have you given up on finding any survivors? >> at this stage it seems unlikely that there are any survivors in the - in the landslide - that could be recovered from the landslide. the focus are the families that have lost their homes. trying to get them assistance that they need. >> a few of the residents have been expressing anger to the team. saying it's disorganised. no one is telling them what happened. what is the problem there? >> at this stage there are many people who wind up waiting for assistance. a lot of organizations, in coordination with the afghan government, the agency - what we'll need to do is just respond, if that is possible, to

people's needs. it takes time. it's a remote area. it's very rough to get up here. machinery and trucks. but they can mobilize aid between hours of the disaster striking, so -- >> i am sure it's a difficult task. >> how concerned are you about the weather. and the fact that rain could bring more mudslides and affect those that have survived? >> yes, this is an area that is highly prone to natural disasters, flood, landslide and people are concerned another will hit. and a lot of people have left their homes, but at this stage we are responding in a safe area, away from the landslide zone, but it is a concern throughout the region. >> thank you for talking to us. good luck with rescue efforts.

in the burning building were victims of mob justice carried out by supporters of kiev. on the other side, of course, people will say that a peaceful march was broken up by gun-wielding pro-russian mobs. there are overarching questions, of course, who started the fire when both sides lobbed molotov cocktails at each other, and who was inside that building. the government suggests there is evidence that among the dead were russian citizens, people brought across from nearby pro-russian transnistrya, a breakaway province of moldova. turning to the police will not help. they said a government-led commission of inquiry is under way. the prime minister from kiev, is in odessa and blamed the security forces for failing to act to stop the violence. senn european military -- seven european military observers held hostage by

strike for 100 days. peter greste's father hopes he has the strength to endure. >> his number one priority, as we are hoping for him, is to make sure he keeps himself as wholly together from day to day as is possible. and, you know, no doubt his faith, his belief is that if he can keep doing that then perhaps he may not be too daunted if it runs to, you know, a year's anniversary. >> u.s. president obama emphasised the importance of a free press during the annual white house where are correspondent's dinner, making reference to journalists that risk their lives and liberty in places like egypt. >> tonight reminds us that we are lucky to live in a country where reporters get to give a head of state a hard time on a daily basis, and once a year

give him or her the chance to return the favour. but we also know that not every journalist or photographer or crew member is so fortunate. as we celebrate the free press, our thoughts are with those in places around the globe - like ukraine and afghanistan. and syria. and egypt, who risk everything, in some cases give their lives to report the news. >> yemen's army stepped up its offensive against al-qaeda in the south. hundreds of vehicles have been sent. they sent troops to two provinces following u.s. and yemeni drone strikes. it's trying to drive al qaeda out of the area. more than 20 government soldiers have been killed. the army says it's killed more than 28 fighters including a senior leader. still ahead - campaign countdown in south africa.
