because of the risk. talks resume, aimed at averting strikes by thousands of heathrow airport workers. rival demonstrations are taking place in hong kong where tensions remain high after weeks of anti—government protests. and witness history hears from a survivor of cambodia's ‘killing fields', where more than a million people were killed by the khmer rouge. that's in half an hour, here on bbc news. good afternoon. efforts to prevent a derbyshire dam from collapsing, close to the town of whaley bridge, have entered a third day. emergency services are in a race against time to pump water out of the toddbrook reservoir and reinforce the dam. there are fears that more wet weather tomorrow could see water

levels breach the dam, causing serious flooding and a danger to life in whaley bridge. this morning, some residents who'd spent a second night away from their homes were being allowed to return briefly to collect essential items. our correspondent, charlotte gallagher is in whaley bridge. here are some live pictures from just outside whaley bridge, where oui’ just outside whaley bridge, where our reporter is waiting for us. let's talk to our reporter, luxmy gopal, who's in whaley bridge. behind me, the police cordon is still there on the edge of the evacuation zone. down the road is lower wha ley evacuation zone. down the road is lower whaley bridge, that was evacuated. more than 1000 residents had to leave their homes. they were allowed to return to collect essential items for 50 minutes,

including their pets. the vehicle of the missing pet search team drove past, hopefully they found what they are looking for. police have been manning the squadron all morning. it was busy this morning with a continuous flow of residents heading back to collect their items. it has quietened down but local mp ruth george said there could be a need for more police officers to be drafted in to manage the evacuation zone. we know they have brought in more emergency crews, fire crews from neighbouring areas to help with the efforts to remove the water from the efforts to remove the water from the reservoir using high—volume pumps. the work to shore up the damage section, rms chinook was back to drop ballasts on the area, they are stepping up efforts to do all they can to maintain the dam because there is the weather warning for the next 2a or 48 hours, there is the weather warning for the next 24 or 48 hours, met office weather warning warning of imminent heavy rains and thunderstorms, which

could hamper the efforts. there is a sense of urgency. residents have been told there is no way of heading home, not likely any earlier than one week's time. charlotte has been in whaley bridge. military operations enter a third day, an raf helicopter a familiar sight and sound here. crews using sandbags to try to stop homes and businesses below the dam being engulfed. a stream turn to a torrent under margot graham park home. she was one of the 1500 evacuated. she was one of the 1500 evacuated. she was allowed to return home for 15 minutes today to collect valuables.

it was bizarre, the whole of the road is blocked with bags of concrete. it is like a ghost town. we were advised by police we were going at our own risk. yes, all right, it is a risk, really. we sort of knew we needed to get things, do things. as long as you move quickly. i would say listen all the time because they told us if we hear three blasts on the horn, we were to run. bricks and mortar, books and cds, furniture can be replaced but if my grandmother's ring had disappeared in the water, i could never replace that. millions of gallons of water still needs to be diverted and bumps are working around the clock. this is a major incident, make no mistake. if you plan trust, you can see the break level, the stones, that was underwater when we arrived. as you can see, it has quite visibly come

down. small businesses are also suffering. everyday closed is a loss of earnings in that respect. i had builders staying with me, they had to get out quick when they started the evacuation. they are losing as well. not really knowing when i can open back up and take bookings. i have had to advise people we are closed for the foreseeable future, i do not know when they will be open -- i will do not know when they will be open —— i will be open, they need to find alternative accommodation. when storms forecast for tomorrow in this critical situation, everyone is helping enough can be done to save time. charlotte gallagher, bbc news. the outlook of more rain? showers on

the warning area, we are concerned. hit and miss, could be that this area does not catch these terms, could be further north. this is why the warning is pretty important. with thunderstorms, i suppose comes down, it is such an amount, normally you get a surface run—off quickly. but the ground is sodden, isn't it? it could get into the waterways? we don't want thunderstorms over or in the surrounding area tomorrow. the hit and miss nature, hopefully they will keep clear from the flooded areas. just for sunday? yes, details could change, could expand further south or north. at the moment, this is how it is looking with that risk of heavy showers and storms from the day tomorrow up until 10pm sunday. of heavy showers and storms from the day tomorrow up until 10pm sundaylj know day tomorrow up until 10pm sunday.” know you are watching things for us, thank you. police are at the scene of a crash in west belfast, where it is understood that a car struck a number of people outside a cemetery.
