welcome to bbc news, broadcasting at home and around the globe. i'm gavin grey. our top stories — as russia demands the us proves the syrian government used chemical weapons on its own people, britain's defence secretary says moscow is to blame for every single civilian death. clashes on the streets of venezuela — thousands protest against a political ban on the leader of the opposition. more details emerge about the main suspect in the stockholm lorry attack — the man, from uzbekistan, was known to the intelligence services. and a sticky situation in canada's maple syrup industry — we talk to the woman who's rebelling against her fellow producers. britain's defence minister says russia is to blame for every single

civilian death in the chemical weapons attack in syria. michael fallon calls the kremlin "responsible by proxy," as the principle backer of syria's government. his colleague, the foreign secretary borisjohnson, had already called off a visit to moscow this week. but russia is defiant, hitting back at mrjohnson's decision, as well as demanding evidence for the united states's claim that the weapons were being stored in the syrian airbase targeted by its missile strike. here's our diplomatic correspondent, james robbins. this was president trump's message to the syrian government and its russian backers yesterday, delivered with force. the united states and her allies reject syrian denials they used a chemical weapon against civilians, including children. now, britain has followed up with a diplomatic rebuke. boris johnson's called off talks in moscow on monday and issued a written

statement instead: the planned visit by borisjohnson to moscow would have been the first by any british foreign secretary for five years — a long gap, reflecting the very bad relationship between britain and russia which already existed. but the events of the past week in syria have now provoked an even deeper crisis. russia's first response came in this tweet from their embassy in london, accusing borisjohnson of "theatrics for lack of argument" and inviting people to listen instead to what they call russia's "soft power." a link leads to this excerpt from tchaikovsky's patriotic 1812 overture, celebrating past russian

military victory. instead of seeing the russians on monday, borisjohnson will be talking to america's secretary of state, rex tillerson, and other allies to agree on next steps. but some syrians who've suffered most, like abdul hamid al yousef, want further military action. he lost 20 members of his family, including his 9—month—old twins aya and ahmed. and it was a photograph of the dead twins being carried by theirfather which helped persuade president trump he had to order the missile strike. translation: i would like to thank president trump and the us administration on the initial steps they took against the airport that killed my children, and all the martyrs. but i didn't expect the strikes to stop. i was surprised. why did president trump stop the strikes? why one airport? why one base? but tonight, russian television has been showing pictures it says show

syrian aircraft flying once again from the base damaged by america's cruise missiles. next week, the political message of that attack will be reinforced when rex tillerson, not borisjohnson, goes to moscow for the trump administration's first meetings there with the russian leadership. they will be very tough encounters. james robbins, bbc news. thousands of people are taking part in anti—government rallies in caracas and cities gci’oss venezuela. they are angry at the government's ban of the country's top opposition leader, henrique capriles, from office. the two—time presidential candidate was banned friday from holding political office for 15 years. greg dawson reports. in the heat of caracas, demonstration quickly turned to destruction. a group of around 100 protesters vandalised and set fire to an office of the supreme court.

even this water cannon tank wasn't enough to douse the anger. but before all the tension and tear gas, thousands had gathered to support the man they want to see take power in next year's elections. henrique capriles was seen as the opposition's best hope of defeating nicolas maduro. on friday, he was banned from politics for 15 years, accused of administrative irregularities. translation: the ban will never have an effect, it's just to demoralise us, to take hope from the people. it's to keep me from being a candidate orfrom being president. but this is about venezuela, and we're going to fight to change our country. opponents of president maduro say the ban is part of his concerted effort to stifle democracy. the unrest was initially sparked by a supreme court ruling to limit the power of the country's opposition—controlled national assembly.

the court eventually backed down but accusations of autocracy remain. translation: this is a dictatorship. the people on the street are demanding elections — that's my reason for being here. in venezuela, we're not living, we're surviving. there's no food, no medicine, no security. the shortage of food and medicine is a symptom of the country's wider economic problems for which the government and opposition blame each other. a 3—year recession has led to steep inflation and low salaries. nicolas maduro says us—backed business elites are responsible for the downturn, but these people have stopped listening and venezuela is facing the biggest sustained protest against its leader for three years. greg dawson, bbc news. earlier, i asked senior fellow at the washington office on latin america, david smilde, about whether he thinks these latest protests will have any affect. it's not clear if they're going to have any effect.

these protests have been going on for a long time but really there's been a lull for about six months in protest. the opposition was quite demoralised for several months after the dialogue broke down, after the recall referendum was postponed last october, and they've reallyjust activated in the last two weeks, i think that is in large part because of the actions of the international community, the discussions on behalf of the regional countries and multilateral institutions. nicolas maduro remains low in the popularity stakes — is this his attempt to try to boost his chances of survival? well, i think they're doing everything they can to try to postpone elections, they postponed the recall referendum last october, they postponed regional elections, and now what they're trying to do is basically trying to tilt the playing field far enough so that if they have to go to elections they can potentially win them.

they disqualified henrique capriles on friday, they're also in the process of party re—validation where they disqualified a number of opposition parties. so they're trying to restrict the opposition leadership so if they do have to go to elections they would do better than they would do ordinarily. one factor we haven't talked about is the trump administration, which has suggested it's not going to be quite as hands off as its predecessor. there's a lot expectation from the maduro government that trump would be hands off, in part because they thought trump was close to putin and would just be following his america first policy. but as it turns out, trump is actually taking it up and the united states has actually denounced the venezuela with some vigour and it seems like it has their attention on the case. has that led to any splits within the way

the government's running? the government's always seemed quite unified behind nicolas maduro, has that changed, do you think? one of the big things that has also emboldened the opposition is last week, when the supreme court put forward these rulings trying to strip the national assembly of its powers, the attorney general actually spoke out against it, saying it was unconstitutional — that was a very rare manifestation of dissent within the government, within chavismo. so that has been a very important point and i think that's something everyone has their eye on, the opposition has been motivated by. thousands of people are expected to gather at services in the swedish capital stockholm later, to remember those killed in friday's terror attack. four people died when a lorry was driven into them on a busy shopping street. police are still investigating whether a device later found on board was a bomb. from stockholm, maddy savage reports.

thousands of people spend saturday paying their respects. and after police reopened the shopping street where the attack happened, many were quick to find new ways to make their mark. in the old town's mediaeval cathedral, there was a special service to remember the victims, attended by sweden's prime minister stefa n lofven. earlier, police revealed that when they towed away the delivery truck used in the violence, they'd made a disturbing discovery. we have found something in the truck, in the driver's seat, a technical device which should not be there. i cannot at this stage say that this is a bomb. the man they think was behind the wheel has connections here, a diverse working—class suburb in the north of the city. he hasn't been named but he is 39 and originally from uzbekistan. several others had been arrested, too, following raids in different locations. security remains tight but locals

are expected to gather for a peaceful rally later. they've been told to leave politics at home and come together to show their love for sweden. maddy savage, bbc news, in stockholm. well, plenty of people offering support to the victims near the scene. dan johnson has been to the department store where the vehicle came to a stop. this the department store in the centre of stockholm where the truck hit yesterday. the security barriers have been put up to keep people back. these have become the focus of people's tributes, people placing flowers and attaching messages, placing a teddy bear. we spoke to a couple who were here in the basement of the department store yesterday when they heard what sounded like a train, they said, and they said they wanted to come back today just to show they cared. police arrested the driver, they believe, a few miles out of stockholm. he's still being questioned today. they say he's a 39—year—old from uzbekistan who's been living in sweden, but they wouldn't

say for how long. there are sensitive issues around the nature of this open society that embraces everyone. there are going to be issues around security and how sweden reacts to this. this street has only reopened tonight and people have come to see exactly where this happened. this is the front of the department store here — you can see where it's boarded up, this is where the truck ended up yesterday in flames when it hit those people. even late at night, people want to come here to think, reflect, and to place a message and everyone's thoughts with those four people who died here and those who were injured and are still being treated. norwegian police have carried out a controlled explosion on a device resembling a bomb which was found in the centre of oslo. the gronland area of the capital oslo has been cordoned off and a suspect has been detained. officers in some norwegian cities

are carrying guns in response to the lorry attack in neighbouring sweden. earlier, i spoke to local journalist fredrik drevon who was at the scene. i am right in the heart of the gronland area, just near the central station of oslo. now, the police cordon has been lifted. life is going back to normal. i can confirm that there was a controlled detonation. i heard the blast myself. it was quite a big blast. behind me, you can see a green tarp. behind that is a tarp about 20 metres back, which is where the bomb or bomb—like device was detonated. what sort of an idea might there be for a target round there? it's obviously not right in the city centre. it's really close to the city centre. it's very close to one of the biggest hotels. there's a traffic overpass here.

an attack here could create a lot of chaos. it's an area that has many bars and restaurants. it also has an immigrant population. it's a safe area and very popular area. and we are now seeing the situation de—escalating. police are still having this little area behind me cordoned off, about 50 square metres. it's just a little area where they are cleaning up after the detonation. this is very unusual for norway, isn't it? yes. the last time i saw someone like this was in 2011, when there was a blast in the centre oslo, and the massacre on utoya island.

to see police carrying mp5 machine guns is very rare. and to see this kind of sealing off of a very big part of oslo. but i could say that from what i've seen from around the city, there has been no kind of big expressions of fear or panic. outside many bars around town, people have been going about their lives, even if they heard about the news. stay with us on bbc news. still to come — the basque separatist group eta has now handed its weapons to french police, who say there are over 3.5 tons of them. 55 years of hatred and rage, as theyjump up on the statue.

this funeral became a massive demonstration of black power, the power to influence. today is about the promise of a bright future, a day when we hope a line can be drawn under the bloody past. i think that picasso's works were beautiful, they were intelligent, and it's a sad loss to everybody who loves art. this is bbc news, i'm gavin grey.

the latest headlines: russia has called on the us to provide evidence for its claim that there were chemical weapons at the syrian air base targeted by an american missile strike on friday. venezuelan police have clashed with protesters during a mass demonstration against a decision to ban the main opposition leader from politics. nearly 3.5 tons of explosives, and dozens of guns, have been found at eight sites belonging to the basque separatist group eta. that is according to the french authorities. it follows the group's decision to hand over all their weapons, in their bid to end more than four decades of violence, which has killed more than 850 people. our chief international correspondent lyse doucet reports from the french basque city of bayonne. arms caches uncovered.

french police carry the weapons away. eight hidden dumps surrendered by eta. three tonnes of explosives, 120 guns. today, in the basque region in south—west france, a peace rally. they also want to see proof on the big screen. a video of an arms dump encircled by volunteers. basque civil society played a key role, persuading eta to give up its guns. there were decades of car bombings, assassinations. in eta's bloody campaign for basque independence. eta's file was finally handed over at city hall from civil society to international witnesses. i was allowed to sit in on this ceremony. everyone spoke of

an historic moment. i'm convinced that eta is handling the weapons it has under its control. i'm not sceptical, because eta declared a ceasefire and end to violence six years ago, and we monitored the ceasefire, and since their declaration, there have not been any incidents of violence by eta. for spain's government, they are still terrorists. translation: the terrorists cannot expect any kind of favourable treatment from the government, and even less impunity for their crimes. joseba goikoetxea, a local polce chief, one of many victims. his wife, rosa, remembers every detail of the day eta shot him. translation: my son told me, "mama, be strong." any steps towards peace are good, she now says, but accuses eta of making too much of today's ceremony. but it mattered to many basques. you can really feel the excitement here in the basque region,

a sense of something important happening. but 50 years of violence have left a deep wound, especially in spanish society. a dark chapter is ending but a reconciliation has yet to start. lyse doucet, bbc news, bayonne. a prison in uruguay is encouraging inmates to set up businesses inside the jail. punta de rieles is a progressive, "open" prison just outside the capital, montevideo. its culture is built on the prison director's belief that if the context changes, the man changes. bbc news went to meet some of the inmates, to hear how the scheme works. there is a sticky situation over maple syrup in canada. controlled by one organisation, one producer is attempting to fight the provincial syndicate. now, canada's highest court is deciding whether to hear her appeal. in quebec, producers have decided democratically to work together we're able to develop the market,

and make an industry of maple syrup, because before that, it was just something you do on the side. but now, people are doing that for theirjob. they are making maple syrup, full—time. sticky business of the syrup industry. a quick reminder of our top story. russia has called on the us to provide evidence for its claim that they were chemical weapons at the syrian air base targeted by an american missile strike. this is bbc news. hello there, good morning. sunny weather at the masters, sunny weather here, too, and believe it or not the temperatures are very similar as well. now, yesterday we had highs widely 20, 21 for england and wales. lovely day at aberystwyth and once again in aylesbury, with the blue skies. and more of that sunshine to come today, too. we are going to see some changes come into the north—west, though. this cloud has been close by over

the past day or two, and it will start to move into the uk over the next 2a hours, and bring with it a significant change in the weather. well, clear skies ahead of that means it is quite chilly first thing this morning, and maybe one or two mist and fog patches across southern parts of england and into east anglia, but those won't last long at all. but once the sun comes up we're going to find the pollen levels rising, high again across england and wales, probably for the last day in a while. the sunshine will be there in the morning, lifting that mist and fog across england and wales. sunshine to start with across southern and eastern scotland, but more cloud moves down from the north—west, with some rain, and we could see cloud filling in across the irish sea, too. so a different look to the weather for scotland and northern ireland on sunday. in the afternoon we have this cloud, the rain becoming light and patchy as it moves across scotland. not much rain for northern ireland, either, but temperatures will be lower. later in the afternoon, we'll see

this rain across north—west england, so too west wales. it may arrive a little sooner across cornwall, but you can see in exeter it is still sunny into the afternoon, and for many central and eastern parts of england, lots of sunshine, very warm as well. 2a or 25 degrees in eastern england, just like augusta. a warm day in sunderland for the football in the premier league, but those changes as that cloud arrives in merseyside. and this is the last of the warm air, on sunday, for quite awhile, i suspect, as colder air comes behind that weatherfront, on a north—westerly wind, once again that weather front producing little or no rain. again, it is dry across the south—east, as it has been for a long time now, and most places will be dry on monday. there will be more cloud developing than we've seen over the weekend, a few showers here and there, and those showers in northern scotland could be heavy enough to give some wintriness, particularly over the hills. it will be that cold, struggling to make single figures in northern scotland, and a drop of eight, nine degrees across parts of england and wales, a much chillierfeel to the day on monday, and quite a shock to the system, too. that chilly north—westerly airflow

gets cut off by high pressure building in from the atlantic. and around the top of that we get a westerly wind, which will blow in more cloud across scotland and northern ireland. quite gusty winds, too. some heavy rain for northern scotland. england and wales, though, should have lighter winds. it should be dry, and once again we will see some sunshine. the latest headlines from bbc news. i'm gavin grey. britain's defence minister michael fallon says russia, as syria's main ally, is to blame for every single civilian death in a chemical weapons attack. russia is demanding evidence for the united states's claim that weapons destroyed in a us missile strike at a syrian air base were used in the chemical attack. police in the norwegian capital oslo have carried out a controlled explosion after finding a bomb—like device in the city centre. the area's been sealed off while investigations continue. a suspect has been detained. police in norway began carrying guns
