hello and welcome. kenya's opposition leader has described the country's electoral commission has brought in after the supreme court declared last month's presidential poll null and void because of irregularities. the selections must be held within 60 days. after the verdict there were celebrations in mr odinga's hometown as low as other opposition areas. the president said he disagreed with the ruling but would respect it. celebrating a new lease of life. veteran politician raila odinga gets one more chance to run for president. a last—minute decision to challenge the result of the presidential election paid off. the presidential election held on the 8th august 2017 was not

conducted in accordance with the constitution under the applicable law, rendering the declared result invalid, null and void. a shocking and rare judgment. the judges did not limit themselves to what happened on election day until the results were announced. rather they looked at the electoral process in its totality from voter registration to civic education as well as the campaigning and procurement of election materials. and so, in a sense, thisjudgment sets a strong precedent for election disputes globally and a high threshold for the conduct of elections. outside the court, celebrations erupted among opposition supporters. it's now back to the drawing board for presidential candidates. as much as i disagree with it, i respect it. i disagree with it,

because, as i have said, millions of kenyans queued, made their choice, and six people have decided that they will go against the will of the people. the court directed the electoral commission to organise a fresh election. but the opposition says it has no confidence in the current commission. they have committed criminal acts. most of them actually belong injail. and therefore we are going to ask for prosecution, of all the electoral commission officers who have caused this monstrous crime against the people of kenya. the constitution states that a new election must be held within 60 days. for now, though, opposition supporters across the country are basking in the glory of the court victory. anne soy, bbc news, nairobi.

and anne spoke to us earlier. she explained why the international election monitors, who declared the vote to be free and fair, have come under fire after today's ruling. the international observers were criticised for rushing to endorse a process , eve n criticised for rushing to endorse a process, even before the final result was announced. but they did also emphasise the importance of seeking legal means of dispute resolution and we believe that that pressure is what led to the petition was decided today. the judges pressure is what led to the petition was decided today. thejudges made pressure is what led to the petition was decided today. the judges made a radical decision. it goes against the norm even in the commonwealth wherejudges generally the norm even in the commonwealth where judges generally tend to show restraint. but then by so doing they have demonstrated their independence. anne soy. and you can get much more on this story at our website, including this piece by our correspondent

alastair leithead, looking at what's next for kenya. within the past few minutes, plumes of thick black smoke have been seen rising from a chemical plant in texas, which was hit by severe flooding earlier this week. the owners of the plant have warned the cooling systems have failed and it is impossible to stop it catching fire. authorities have evacuated residents in a 2.5 kilometre radius around the plant. it is located about a0 miles south—east of houston. that information coming in the last few of a chemical fire in texas. the floodwaters around houston itself have begun to recede. president trump will visit the area on saturday. in his weekly address, the president outlined his relief plans for storm harvey. at the request of the governor i declared a major disaster in the

life has been ruined. translation: i have lost everything. i had a cow and a goat. they were both killed. my house is totally broken and i'm just left sitting here by the side of the road. i have nothing left. i just don't know what to do. the people here are subsistence farmers, some of the poorest and most vulnerable people on earth. the floodwaters have begun to drain back. only to reveal the wreckage of homes and of lives. more than 500 people have died just in this one indian state, 17 million affected, and now there are new concerns — houses, schools, roads —

they all need to be rebuilt and then of course there is the danger of disease. filthy water, hot weather, and the lack of basic sanitation can be a deadly combination. people remained in water three days, four days. their homes were submerged in the water. they remained in the water but, due to waterborne diseases, they were drinking contaminated water, so it's a huge risk. and this is a snapshot from just one tiny part of a catastrophe that is unfolding across much of south asia. the region floods every year, but this is different. exceptional rains have brought devastation right across the foothills of the himalayas, from bangladesh in the east, across northern india and nepal, and now up into pakistan. the death toll from the collapse of a single building in the indian financial capital, mumbai, rose to 33 today. police suspect it was weakened by the torrential rains. and 16 people have died in flash floods in karachi, pakistan's largest city.

laid down. it's understood an ex—gas officer who now works for the home office has also been suspended. the home office decides who is detained in centres like brook house. it says it condemns any actions that put the safety or dignity of detainees at risk. adding that gas needs to ensure there is a thorough investigation into the allegations. the company says it has alerted the police. let's take a look at some of the other stories making the news. the speaker of the us house of representatives has urged president trump not to scrap a programme that protects young undocumented migrants, known as ‘dreamers‘, from deportation. hundreds of people gathered in los angeles on friday to rally against the roll back. the white house says the president will announce his decision on tuesday. police in north—west england say the former national football

weather service data shows that extreme rainfall has become more common since the 1960s. the international panel on climate change expect such events to become more common in a change expect such events to become more common in a warmer change expect such events to become more common in a warmer world. it is well—known that warmer air holds more water, so as the planet warms up more water, so as the planet warms up his extreme events have the potential to give even more rain than they would have done in previous decades. the plight of myanmar‘s rohingya minority risks becoming a humanitarian catastrophe, according to un secretary general antonio guterres. he is urging the country's security forces to exercise restraint, and says he is concerned by reports of what he called excesses during security operations in rakhine state. according to the un, nearly a0,000 refugees from myanmar‘s rohingya minority have crossed into neighbouring bangladesh over the past week. a00 have died. they are fleeing fighting between rohingya insurgents and burmese security forces. here is the bbc‘s south east asia correspondentjonathan head. this is the naf river, dividing bangladesh from myanmar.

it is two days ago, and people are swarming across, wading, swimming, carrying what they can. this dramatic exodus of ethnic rohingyas, continuing even now, speaks of a terrible conflict on the other side. inside rakhine state, rohingyas are watching, and recording from a safe distance, the destruction of village after village. it is a scorched—earth campaign by myanmar‘s security forces, as they wipe out the communities which they believe harbour rohingya militants who, last week, launched a series of armed attacks on the police. bangladesh doesn't want them, but the rohingyas haven't stopped coming. a stream of humanity, all telling the same terrible stories, of homes burnt, husbands shot dead and of flight on foot to the border.

but, where the river is widest, some of the boats floundered. men, women and children drowned. the death toll in six days of violence right across northern rakhine state can only be guessed at. years of repression and discrimination have led to this. public sentiment inside myanmar towards the rohingyas is almost universally hostile. now, a new generation of militants have armed themselves and attacked the myanmar security forces in multiple locations. and the civilian population is feeling the backlash. over the river, the smoke from wrecked communities sends an ominous warning, that this conflict isn't over, that it might get a lot worse. it is now a week since hurricane harvey slammed into south—east texas, and some people in houston have been making their way back to their devastated homes. the bbc has been following some of them.

these streets i couldn't see, everything was under water. it looked like a big lake. it is pretty bad. i don't know what to say about it. whole lives ruined. you have got to start over. that is how deep the water was. pictures on the wall haven't made it. —— have made it. thank god. i am not going to stay in the house. i am going to go ahead and fix it up, and sell it. i love

the house, i loved everything in it, but you know, there is a time to say let's move on, and that is what i wa nt to let's move on, and that is what i want to do. it is the only thing that will keep me sane. otherwise i will second—guess myself, what could i have done to... for this not to happen. the things i could have done. man, this has changed the whole lot. this is a disaster. trying to find everything to put it backin trying to find everything to put it back in place, and i don't know where to start it. i'm good to see them. they didn't drown. they made it through. so i've still got cats on the roof. looks terrible in here.

stuff everywhere. looks like it's been floating. this is where it started coming in first, the water. i never thought my house would be looking like this. i live down at the corner. very few people here have flood insurance. they probably didn't tell them when they bought in here that the houses would flood. just upset, all the work we have got to do to get it back up. ijust drop the keys somewhere. it is a mess. it is going to be a long, trying time. along, trying, time. one of the most powerful x—ray

machines ever built has officially opened in the german city of hamburg. the facility, which has cost more than a billion euros to build, will be used to study the detailed structure of matter, atom by atom. david campanale explains. hidden nearly a0 metres beneath german cornfields in hamburg's residential areas as one of europe's most ambitious, cutting—edge research project. it will allow research project. it will allow research is for the first time to look deep inside outer. the xfel, as it is known, has been ten years in development, and is housed in the tunnel 3500 kilometres long. —— 3500 metres long. the machine is a particle accelerator that 20,000 times a second can produce a brilliant and extremely short flash of x—rays. brilliant and extremely short flash of x- rays. translation:

brilliant and extremely short flash of x-rays. translation: the light flashes we generate are about 100 femtoseconds long, which is more or less the light needed to cross the human head. reaching the moon takes about a second, so we generate extremely short light pulses which allow us to freeze extremely quick reactions, for example, in biological material. what scientists say really sets the xfel apart is its superfast time structure in the flashes, which will catch proteins and catalysts in the very moment they are made or broken, and even make a film of that change. at the project's head is not driven by questions of immediate use. translation: i am curious in what i may see an five or ten years. . to date i would say not for all the will of the world and i imagine the specific use of it up from the history of science week that often someone said there is no utilisation. what is the need of electromagnetic waves? research is

hope using xfel will lead to new routes in understanding the causes of disease, and to improve the efficiency of industrial processes. the project will begin operations with 11 nations as members of its consortium. just before we go: an astronomer has captured images of the biggest asteroid to pass close to earth in more than a century. asteroid 3122 florence, which can be seen here crossing with stars in the background, came within seven million kilometres of our planet earlier on friday. the space rock measures five kilometres across, and is the largest to pass by our planet this close since nasa's records of asteroids began. keep up—to—date on our website. stay with bbc news. hi there. we have got some decent
