welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is lebo diseko. our top stories: barack obama calls for honesty and decency to be restored in the us government. now president trump hits back. what did you think of president obama at‘s speech? i said i watched it but they fell asleep. —— president obama's speech? after a week of fighting, a fragile ceasefire — the bbc makes it into libya's capital, tripoli. we have a special report. british airways apologises for a data breach affecting thousands of customers — and promises 100% to compensate anyone affected. and us rapper mac miller is found dead at his la home — after an apparent drug overdose. i'll speak to a bbc dj who knew him. hello and a very warm welcome.

barack obama has given a speech attacking president trump, and accusing the republican party of abusing power, dividing america and threatening democracy. in his first major address of the us mid—term election season, the former president said americans were living in "dangerous times." he urged voters to come out in force to support democratic candidates in november, as nick bryant reports. cheering this was barack obama returning to political centre stage. using what has always been the strongest weapon in his armoury — the power of speech. and deploying it against donald trump. hello, illinois. and he addressed this week's explosive revelations that trump appointees are working secretly to subvert the president. you are not doing us a service by actively promoting 90% of the crazy stuff coming out of this white house and then saying, "don't worry — we're preventing the other io%."

that's not how things are supposed to work. this is not normal. these are extraordinary times. and they're dangerous times. these were his strongest criticisms yet of the man who succeeded him and he was scathing about donald trump's response to events last year in charlottesville, the clashes involving white supremacists and neo—nazis. we're supposed to stand up to discrimination. and we're sure as heck supposed to stand up clearly and unequivocally to nazi sympathisers. how hard can that be? saying that nazis are bad? laughter # where at least i know i'm free... donald trump is a counter puncher and just over an hour later, buoyed by strong newjobs figures, he described his reaction to being asked about his predecessor's criticisms. he said, "what do you think of president obama's speech?" and i said, "i'm sorry, i watched it but i fell asleep."

laughter i found he's very good, very good for sleeping. laugther these first seven days in september, which started with a memorial service forjohn mccain, feel like a milestone moment, when the forces of resistance to the trump presidency have asserted themselves more strongly. much of that service was a rebuke to the president, and then came the blockbuster new book from bob woodward and the highly critical column in the new york times, penned anonymously by an administration official. it's unprecedented in modern times to see this kind of public clash between a sitting president and his predecessor. and it speaks to how this divided country increasingly looks like two americas — one that rallies round donald trump, and one that seeks to resist him. nick bryant, bbc news, washington.

meanwhile a former trump advisor who was part of the 2016 election team has been jailed for 14 days. george papadopoulos admitted lying to federal agents investigating whether campaign aides colluded with russia. he'll also have to do 200 hours of community service, and pay a fine of $9,500. thousands of people have been forced to leave their homes after more than a week of fighting between rivalfactions in libya. but now a ceasefire, brokered by the un, seems to be holding. seven years ago, rebel groups, backed by a military coalition, toppled the dictator, muammar gaddafi. since then, there has been political and military chaos. the bbc has the only international news team there. clive myrie sent this report. we're entering a nervous city. only now after a week of fighting and three ceasefires do we think it's safe to enter tripoli. along this same road seven days ago,

fighters from armed groups based outside the capital breached the city walls. but rival factions inside tripoli were ready for the fight. the battles left scores dead, including civilians, and forced thousands to flee their homes. darkness provided no respite. the battles are over for now, but the scars linger. at his family compound, ali el—amari doted on two grandchildren who are now dead. translation: the rocket or missile landed right where the children were playing. there was blood everywhere. 0n the ground, all over the trees. when you see the body of your grandchild in pieces... my daughter had to see it too.

i am very, very sad. i am very sad. ten years. why are we still all fighting? why? 0ne boy was 14 and the other 15. they were buried one week ago today. libya's problems, the deaths, the destruction, are the result of the messy end of colonel gaddafi's rule. the armed groups that helped topple him carved up the country, leaving no—one in overall control. and the militias and groups that stayed within the capital are being accused of being greedy, of siphoning off funds, of ruining the economy. those groups outside the capital now

say they had to intervene. there is a un—backed government in tripoli, but it's accused of allowing the armed factions in the capital to act with impunity. with so many militias and fighting groups seemingly running the country, libya is a failed state. and seizing on that failure have been the people smugglers. the fighting of recent days has ensnared many of the thousands of migrants who are trying to use libya as a gateway to europe across the mediterranean. these people had to break out of a detention centre when the fighting got too close. this man says there was gunfire at night and five people were hit, that's why we escaped, but even as we tried to run, another man was shot. the fighting forced thousands of libyans to free their homes, children to leave their schools.

this woman is a mother of four. she said she wanted to talk to us, and she poured out her heart. "we are tired, we've had enough," she told me. "we had to leave our homes. "i would like to send a message to the world, "we are peaceful people. "we want to live like everybody else, our children to grow up in peace. "why is this happening, why?" libyans are tired of the men with guns having all the influence. and hopes for nationwide elections by the end of the year are now in ruins. once again, an attempt to stitch together this fractured nation has come to nothing. clive myrie reporting. a couple of others stories to tell you about quickly.

in syria, tens of thousands of people in the province of idlib have taken to the streets demanding that the international community intervene to protect them from a government offensive. idlib is the last remain rebel stronghold, and president assad's forces have it surrounded. they're backed by russia and iran, whose planes continue to bomb rebel positions. in brazil, the man widely expected to be the country's next president is recovering in hospital after being stabbed. jair bolsonaro lost 40% of his blood after being attacked at a campaign rally. his son says he probably won't return to campaigning before next month's election. as more unrest shakes the city of basra in iraq, the most revered shia cleric in the country has blamed the crisis on the government. iraq's parliament has now said it will convene an emergency session on saturday. laura westbrook has more. the day began in morning. a funeral for a protester killed during

demonstrations. but it soon descended into another day of violence. —— mourning. people here in basra are angry at the government for not providing basic services. they have long lived with a lack of electricity and high in employment, but the final straw is thousands in hospitalfor but the final straw is thousands in hospital for drink but the final straw is thousands in hospitalfor drink in but the final straw is thousands in hospital for drink in polluted water. —— unemployment. translation: the issue is water. it isa translation: the issue is water. it is a live issue. blood for water. women, too, joined the protests. they say they have been ignored by those in power in baghdad forfar too long. it has led to the most revered shia cleric in iraq to step in. he too placed the blame on those in charge and called for a new government. translation: it is necessary to

pressure the new government to be different from its predecessors. despite his appeal for carlton, different from its predecessors. despite his appealfor carlton, as night falls, the city burns once more. this time the target is the arabian concert. luckily, it was empty when it was set alight. —— iranian. people are angry at iranian influence in iraq. these protester says there is not a iranian embassy any more, and we do not want one. burned and blackened shells of buildings across the city are all thatis buildings across the city are all that is left. 0n the wall of this government building, it says "per the headquarters of satan". back in may, people hoped the election would bring a fresh start. instead, at the city has once again slipped back into violence. —— burn the

headquarters. shares in the electric car—maker tesla plummeted more than 9% on friday after pictures emerged of its co—founder, elon musk, on a live podcast, smoking cannabis with comedianjoe rogan. since then, tesla's chief accounting officer has resigned afterjust a month in thejob, and there reports that the head of human resources also plans to leave. we can speak to our correspondent chris buckler in washington. it's been a pretty wild couple of months for elon musk. how damaging might all of this be long term? the focus is on elon musk and tesla. they cannot be separated in some ways. tesla is elon musk‘s brainchild. the focus on exactly what he has been doing in terms of his particular behaviour is something that could potentially affect the company. certainly, he has made on twitter, a taxi has made on twitter, in some cases, and

brought into focus, and at one stage he seemed to say that he was prepared to take the company private, which was not announced to the board of investors in terms of tesla, and some that seem to come out of the blue. that it sell —— that itself is one thing, but all these questions about elon musk‘s and behaviour, the fact that he has come on this blog asked smoking cannabis, and at one stage wielding a samurai sword, has left a lot of people confused, and affected tesla's share price, because he is so tesla's share price, because he is so associated with the company. bizarrely, when he talked about taking the company private, which is saying he is now not going to do, he used the figure of m20, and then had to deny that he was smoking cannabis when he made that decision, because 420 is sometimes a phrase that refers to marijuana. he has

denied that, but now he has smoked cannabis, and shareholders are watching closely. so much to ask you, but we have to leave it there because we have run out of time. stay with us on bbc news. still to come: cleaning up our oceans — the first attempt to remove decades of plastic pollution starts in the pacific. freedom itself was attacked this morning, and freedom will be defended. the united states will hunt down and punish those responsible. bishop tutu now becomes the spiritual leader of 100,000 anglicans here, of the blacks in soweto township as well as the whites in their rich suburbs. we say to you today, in a loud and a clear voice, enough of blood and tears. enough! translation: the difficult decision we reached together was one that required great and exceptional courage. it's an exodus of up

to 60,000 people, caused by the uneven pace of political change in eastern europe. iam free! this is bbc news, the latest headlines: former president barack 0bama's call for the restoration of honesty and decency in the us government, in an outspoken attack on donald trump. and after a week of fighting in the libyan capital, a fragile ceasefire appears to be holding. british airways could be fined as much as $640 million for a huge data reach.

—— breach. hackers managed to access details of 380,000 bookings made with the airline over a two week period. ba says personal and financial details were compromised, and many passengers have been forced to cancel their credit and debit cards. emma simpson has the story. it's all about the customers. business travellers and holiday—makers, transporting them around the world. but thousands have had their personal information stolen after british airways was hacked. jorge herrera is one of them. he booked tickets with a credit card at the end of august, but has other cards on his ba account, too. he's struggled to speak to the airline all day. i don't think i have to cancel all my credit cards, but i don't know. and so i'm in the process of doing that. and it's going to take a long time. so, what do we know about this data breach? well, it affected customers who made a booking or changed one through the british airways website or ba app from 11pm on august 21 up until 9:45 on wednesday evening.

380,000 cards were affected. ba says hackers stole names, addresses, e—mailaddresses and payment information. that included the card number, expiry date and, critically, the three digit security code on the back. i'm not letting you see my three digit number, because it's a bit like giving you the keys to my safe. now, with an online transaction, this number shouldn't be stored. ba says they weren't. so how did hackers get hold of them? emily here is a cyber—security expert. what could have happened? well, one theory is that a supplier to ba actually got compromised in the first place. so when you are booking a flight on the website, you may not realise, but there is lots of third—party

software that is used within those web pages to do things like process card information. so it could be that they were targeted because they were a little weaker on security, and then used to extract the data. ba says it's sorry, promising compensation for any customers who may end up out of pocket. this was a very sophisticated criminal attack on ba.com, and over more than 20 years that ba.com has been operating, we've never had a breach of that type. this attack doesn't surprise me. we see attacks like this targeting payment and card details all the time. but this is a big industry, and criminals do do this on a daily basis. but it is unusual for hackers to land so much sensitive payment card details at once. it's the first major incident since new data protection rules came into effect, which means ba could face a sky—high fine of around half a billion pounds for the breach. the us rapper mac miller has been found dead

at his home in los angeles after an apparent drug overdose. the 26—year—old, whose real name is malcolm mccormick, previously dated pop singer, ariana grande. he shared the stage with her at the one love for manchester concert last year. fans and fellow musicians have been paying tribute to the rapper on social media. he had just released a new album and was due to start touring later this month. bbc radio ixtra dj semtex joins me on the line now. first of all, i am so sorry, i know you knew him. it is really tragic, so young, as you knew him. it is really tragic, so young, as well. tell us how you came to know him? i know you were one of the first people to interview him in the uk. yeah. i mean, being a hip—hop dj, i always look for the hottest new artist and the greatest music. it was six or seven years ago

icame music. it was six or seven years ago i came across him. when he came to the uk for his first ever show i made sure i got one of the first interviews with him. he was a really cool guy, an amazing artist. he had a lot of fans out there. yeah, something that has been coming out in the tributes in what fans have been saying, and also what people like salonge and chance the rapper is how kind he was. he was a really cool individual, one of the best people. whenever he was in the uk us reached out to me and invited me to his shows, we did interviews whenever he was over. —— in the uk, he reached out. not many artists like that. he was a very thoughtful person and an amazing artist and an amazing mc. i saw one fan talking about how he ought a whole bunch of them chicken after a show in brixton. —— bought. them chicken after a show in brixton. -- bought. yeah, he did the

show in brixton and afterwards we went to nando's and they were closing, so i said, look, we've got a great artist here, so they stayed open, and basically fought —— basically bought food for everybody. like, 20 tables. that was mark miller. —— mac miller. he was this crazy, wonderful guy. everybody around him, where did you knew him oi’ around him, where did you knew him or not, you felt part of that crowd. there was no attitude or anything like that. he was a really great people person, and an amazing artist. it is just tragic what has happened. tell us about his impact asa happened. tell us about his impact as a musician. i know that he opened doors are a lot of artists behind him, as well. yeah, he was... he wasn't the first independent artist, but he was one of the first successful independent artists, and he came through at the same time as other people were doing really well and were starting to make labels. he

was getting a lot of success independently and making a lot of money independently, which inspired other guys to go out and do the same thing. and i think hejust had that essence, he could wrap about anything, he loved the music and the art form. he was just... anything, he loved the music and the art form. he wasjust... hejust inspired us. he inspired other artists. if he was wrapping and you we re artists. if he was wrapping and you were in his vicinity, really, he did inspire a whole generation. dj semtex, we are out of time, but i am really sorry for your loss, and thank you to speaking to us. thank you. every year millions of tonnes of plastic waste flow into the sea around the world. now, for the first time, an attempt will be made to get into the middle of the pacific ocean, to try to clean it up. 0ur science editor david shukman explains. in san francisco, final construction of a massive project with an incredibly bold ambition.

to try to clear the oceans of plastic waste. this animation shows how the huge structure is meant to collect millions of pieces of plastic to make them easier to get rid of. sights like this have shocked people around the world. images of the damage to wildlife have inspired this effort to clean up. if we don't do it now all this plastic will start breaking down into smaller and smaller pieces, and the smaller the pieces are the more harmful and harder to extract from the marine environment. so we feel there is a sense of urgency. there is plastic waste in every ocean around the world but this is the first attempt to clean it up. it will take place in the eastern pacific in a rotating current that traps plastic, what's called the great garbage patch. it's bigger than britain and france combined. how is the project meant to work? a giant tube 600 metres long will float on the surface and bend

into a shape like a horseshoe, drifting naturally with the current and the winds. because it will move faster than all the bits of plastic in the water it should slowly gather them together into a small area. underwater a kind of barrier will hang three metres down to trap plastic below the surface and the design should mean that any fish will pass under it. once the plastic has been drawn into a dense mass it will then be collected by ship, taken away to be recycled. no—one can be sure if the huge system will work. some experts worry it could harm marine life. the major problem is those creatures that passively float in the ocean and cannot actually move out of the way. once they are in, they are going to be trapped there unable to move. for example plankton is the bottom of the food chain, so we really do not want to be taking that out of our oceans.

that is clearly from the teeth of a fish. yes. there is no other explanation. one of the scientists on the clean—up project says because the plastic is being eaten by fish it is entering the food chain so should be removed. it's been there for years. we find plastic from the 70s, from the 805, from the 905. and then we also find languages on those bits of plastic so we will find in the north pacific chinese, japanese, english, so we will try to define where the things may have come from. the plan is to start with one collection device and eventually deploy 60 of them. but all the time plastic is pouring down rivers into the oceans. so on its own the clean—up operation will never be enough. good morning. the weekend is upon us. many of us will see a little bit of rain at some stage in the weekend.

that is by no means the whole story. there will be a lot of dry weather around as well and some spells of sunshine. quite a complex pressure pattern. high pressure to the south. one area of low pressure to the north—east. then this wriggling weather front pushing in from the atlantic. this is essentially going to send a pipeline of moisture in across central parts of the uk. for wales, the midlands, northern england, we will seek outbreaks of rain through the day, the odd heavy burst. some of that rain dribbling down into east anglia. the further south you are more in the way of dry weather, some brightness and brighter skies to be had further north through saturday afternoon. extra cloud through the far north—east of scotland. get yourself into some sunshine. aberdeen i6, 17 in glasgow. a cool fresh feel, similar story for northern ireland. northern england into wales and the midlands, outbreaks of rain at times, the odd heavy burst over the hills, particularly. it will be quite breezy. breezy further south as well. towards the channel islands you may see breaks in the cloud and a little bit of sunshine. remember that pipeline of moisture, it piles its way in as we go through saturday night into sunday.

at this stage the rain will drift further north as well, perhaps getting into southern scotland. cool in north—east scotland, further south with a fair amount of cloud it will be mild. outbreaks of rain across western and some northern parts of the uk. there could be patchy rain and drizzle around through the morning, close to newcastle, as the great north run gets under way. as we go on through the day i am hopeful the cloud will start to break up. we'll see spells of sunshine developing into the afternoon.

temperatures around 16 or 17. it will be fairly breezy. across the rest of the country, a similar story. rain will drift across many northern parts of england, northern ireland, and scotland. the rain continues across northern scotland through the day. some thundery showers later on. increasingly windy. further south, more sunshine towards the south east and some slightly higher temperatures as well. moving out of sunday and into monday, high pressure still influencing the weather in the south. more frontal systems in towards the north—west. it will be northern and western parts of the uk that will see outbreaks of rain, often breezy conditions. further south, more in the way of dry weather. some sunshine. and it will start to warm up as well. this is bbc news. the headlines: barack obama ba rack obama has barack obama has launched an outspoken attack on donald trump, and has accused the republican party of dividing democracy. he urged people devote to the democrats in the mid—term elections. donald trump said the speech sent him to sleep. a fragile ceasefire seems to be holding in the libyan capital after

a week of fighting rival factions. 47 people have been killed and nearly 2000 families have been internally displaced. british airways could be fined as much as $650 million for a huge data breach. hackers managed to access the details of 380,000 bookings made with the airline of a two—week period. the airline has apologised and says it is committed to paying compensation. now on bbc news, it is the week in parliament.
