in an age of terror? khalid masood was active on the messaging network whatsapp just before he started his murderous rampage. whatsapp messages are encrypted — only the sender and the recipient can see them. masood is said to have been acting alone, but the authorities would dearly like to know what he said and who he said it to be for he began. the security services, says the home secretary, need access. we need to make sure that organisations like whatsapp, and there are plenty of others like that, don't provide a secret place for terrorists to communicate with each other. it used to be that people would steam open envelopes orjust listen in on phones when they wanted to find out what people were doing — legally, through warrantry — but on this situation, we need to make sure that our intelligence services have the ability to get into situations like encrypted whatsapp.

the home secretary says she'll be talking to the big tech companies this week about loosening the privacy around messaging networks. for law enforcement, change cannot come soon enough. at the heart of this is a stark inconsistency between the ability of the police to lawfully intercept telephone calls but not when those messages are exchanged via a social—media messaging board, for example, and that is an inconsistency in society, it surely is, and we have to find a solution through the appropriate legislation. it's notjust encrypted messaging that alarms the government. there's also deep concern over the threat of online radicalisation — websites that glorify violence and encourage viewers to take part in terror. it's not hard to find. the tech companies say they take material like this down as quickly as they find it.

a new law on encryption, says the labour leader, would go too far. they have huge powers of investigation already, there is a question of always balancing the right to know, the need to know, with the right to privacy. whatsapp says it is cooperating with the police, but the trade—off between freedom, privacy and security is under sharp scrutiny, as the country mourns the carnage of wednesday afternoon. jonny dymond, bbc news. there's been another arrest in connection with the westminster attack, a 30 year old man from birmingham is being questioned. the police believe khalid masood acted alone on the day, but have been appealing for more information from people who knew him or came across him. our home affairs correspondent tom symonds reports. it took little more than a minute — a crude assault on the heart

of westminster which left its victims in its wake. khalid masood mounted the pavement on westminster bridge atjust after 2:40, according to new information from the police. he drove fast, sending people running for cover, and 30 seconds later crashed into railings. someone managed to make the first 999 call within 21 seconds. but masood was out of the car and, after attacking a police officer, was shot dead half a minute later in the grounds of parliament. from start to finish, it had taken 82 seconds. so those are the facts, but why did it happen? tellingly, police now say they may never know the answer to that question, but they are looking closely at khalid masood's life in an attempt to discover what motivated him. today, yet another home was being searched near his most recent address in birmingham. one man who lives around the corner is still in custody. we know khalid masood had a violent past, but there were times in his life when he may have adopted

extreme political views, possibly while serving a prison sense in 2003, or during two periods living in saudi arabia. 0r after moving to luton around 2010, at a time of confrontation between young muslims and right—wing activists. the kind of people who commit terror... the answer to that question — why — could be complex. there could be anything between 15 to about 28 different reasons, different tell—tale signs, and my argument has consistently been that the government has obsessively focused on one, which we refer to as islamist ideology. ideology is important, but it is but one factor. this tragedy has again led to questions about the government's strategy to fight radicalisation. those who have to spot tomorrow's potential terrorists say the challenge is daunting. tonight the met have said that there

is another arrest, a 30—year—old man taken into is another arrest, a 30—year—old man ta ken into custody is another arrest, a 30—year—old man taken into custody on suspicion of preparing the terrorism. that is on top of a 58—year—old man who has beenin top of a 58—year—old man who has been in custody for three days and the 32—year—old woman who's been released on bail. most of the searches have been taking place, are now complete and just one are still ongoing. there is the sense that this is just the end of the beginning. sinn fein says the current phase of inter party talks at stormont castle have come to an end. the party say they don't intend to nominate their stormont leader michelle 0'neill as deputy first minister. the downbeat comments came ahead of tomorrow afternoon's formal deadline for the creation of a new power sharing executive. dup leader arlene foster responded by saying there was little to suggest that sinn fein want to secure agreement, and that her party was ready to discuss how to secure new arrangements for northern ireland. the northern ireland secretary has

urged parties to agree to work together to form an executive. i'm joined from belfast by our ireland correspondent chris buckler why has everything stopped? there has not been much optimism about these talks. the parties have had three weeks in the stormont election at the start of the month to try and negotiate and repair the damage in relation to which resulted in the colla pse relation to which resulted in the collapse of power—sharing at stormont back injanuary. that then deputy first minister martin mcguinness of sinn fein resigned and of course he died last week. negotiations have been continuing at stormont and this afternoon sinn fein, ina stormont and this afternoon sinn fein, in a surprise move, basically to those negotiations to an end. they said that they had come to the end of the road and that the talks had run their course and that they

would not be nominating their stormont leader to the position of deputy first minister, that is the joint head of the northern ireland executive, tomorrow. as things stand the northern ireland assembly had been scheduled to meet tomorrow for the largest parties, in theory, to nominate the first and deputy first ministers, said that would be the democratic unionist party is that the position of first minister and sinn fein for the deputy first minister, but if those parties cannot agree and i have of them decides that they are not in a position to nominate and they cannot go along with the terms of being in government with the other then there is no devolved government the northern ireland. that is not the state we have got to, sinn fein are saying unequivocally that they are not going to be nominating for the post of deputy first minister, therefore the deadline will pass tomorrow with no power—sharing executive still impose will start northern ireland face an even more uncertain political future.

northern ireland face an even more uncertain politicalfuture. the ddp leader has admitted a statement. macro yes the democratic unionist party death has said that there is little such suggest that sinn fein wa nted little such suggest that sinn fein wanted to secure an agreement. —— the democratic unionist party leader has said. she says that throughout the course of yesterday sinn fein behaved as if they were the only participants whose mandate mattered. it is clear she is placing the blame very firmly on sinn fein. but they are placing the bane very amicable democratic unionist party and on the british government, they say that the two main sticking points, if you like, are firstly the running of new organisations and agents to investigate killings in the troubles and second and irish language act,

they want official recognition for they want official recognition for the irish language. two major issues which at the moment cannot be overcome. chris, thank you per the moment. the home secretary, amber rudd, has called on technology firms to allow access to encrypted material in terror cases. it's thought the westminster attacker, khalid masood, used the whatsapp messaging service seconds before he killed four people last wednesday, but it's not known what was communicated. whatsapp says it is cooperating with the authorities. the labour mp chi 0nwurah — who's the co—chair of parliament's communications and technology forum — joins me now. by by webcam. thank you very much for joining us this evening. how much sympathy do you have fought what amber robb has been calling for?“ one could possibly even begin to understand what she was calling for then i might be to have some sympathy for it. i think she was saying that, she confused hashing

and hashtags, ithink saying that, she confused hashing and hashtags, i think she was saying was that we needed to be able to access all encrypted material or that security services needed to. i feel that that is not a solution, it will not work. that is like calling eve ryo ne will not work. that is like calling everyone to live in glass houses, because some people might be doing things which are terrible and we need to stop. it does not make you more resilient. if we undermined the entire encryption of the internet then we will stop financial services, we will stop all kinds of really important and indeed security services. we do not want to create a back door into all encrypted on the internets, because that will really undermined our services that we need to keep secure. if she is saying that the communications of the terrorist, who committed an

unspeakable act, should now be accessible in some way, then that i do have a lot of sympathy with and thatis do have a lot of sympathy with and that is where we need to look at what the technology can offer in the right legislative framework. the problem is that we do not have a clear idea of what the government wa nts. clear idea of what the government wants. i do not think they have a clear idea of what they want and in those circumstances it is hard for technology to respond. isn't it understandable, it is still early days, not even a week has gone by since this attack happened. it would be very useful for the intelligence services to know what that communication on whatsapp contained. i'm sorry to say this, and i do not wa nt to i'm sorry to say this, and i do not want to criticise a fellow mp for lack of technical knowledge, because not everyone can have that, she should been better briefed, but we have known about the encryption privacy security services access

balance that we are trying to establish for years now and indeed the act that was rushed through parliament was partially in response to that. this has happened and it is an atrocity committed by a man with hugely tragic circumstances, but equally i think many people have said that we knew it was a question of when not if. absolutely there was not early days in trying to establish what the balance should be between privacy and security and access to encrypted messages. this is something we had known about for a long time and i really believe the home secretary should of been on top of it and should have known what it was that as a government, responsible for security, what is that she's aiming for. finally, what

would you say to the intelligence services who say they need access to the encrypted messages or they're trying to work blind? that is absolutely right and i do believe that access is required, but that is not the same as access to all encrypted material in real—time. this is the key difference. the security services saying they want access to everything that is encrypted on the internet, financial transactions, everything all the time? i exceed you not think that is the case. 0r time? i exceed you not think that is the case. or are they saying they wa nt to the case. or are they saying they want to look at ways with the right oversight and authority to be able to access particular included m essa 9 es to access particular included messages which is no doubt on the terrorist‘s device and which if that specifically is the case then that is what we should be working with whatsapp and you tube and others to achieve, because it is certainly the

case that they are not being proactive enough, the social media giants, in addressing this. but the government is not being clear enough about where it is trying to aim to. we really do not have a path to a good compromise on that key point between the rights of the individual and access to encrypted material. thank you very much. thank you. more than thirty people have been injured, two of them seriously, in what's suspected to have been a gas explosion on the wirral. the blast caused extensive damage — it could be several days before people who live in the area are allowed to return to their homes. linsey smith reports from the scene. the scale of the devastation shows just how powerful the explosion was. this was a dance studio, it'd been full of children and our before. the blast was heard six miles away. this

sound of the building blowing up was ca ptu red sound of the building blowing up was captured by a car's dashboard camera. 0h captured by a car's dashboard camera. oh my god! 33 people were taken to hospital. a multitude of injuries that happened with the two patients that are gone through to the major trauma unit at aintree, they have significant injuries. within one of the damaged homes, christine pickup had been baby—sitting her grandchildren. i don't know how we walked out of there. i think the children, because their bed is slightly higher than the low windows in these old houses, the blast lifted the mattress up and threw it over the children, cos they said they felt things hitting them, but they weren't bruised or sore, and i think the mattressjust saved them with the...masonry. police are now leading an investigation. a number of local people say they smelt gas yesterday and on friday. national grid engineers are at the scene and say they have found no faults so far.

with the scale of damage here, many residents will spend at least another night out of their homes. the community here say they are shocked by the events of the last 2a hours, but it will be sometime before they're quite residential areas back to normal, not only does the rubble from the damaged building have to be removed, but beyond that there are homes who simply have no windows or doors because they were blown out by the force of the blast. that means there will be people here who are displaced for some to come. you were watching bbc news, our headlines this evening. ‘no place to hide' — the home secretary says intelligence services must have access to encrypted messages. khalid masood is thought to have been using whatsapp moments before he killed four people. people living close to a explosion

on merseyside last night reported smelling gas beforehand. sinn fein says it's the ‘end of the road' on power sharing in northern ireland — as talks break down ahead of tomorrow's deadline the move was criticised by democratic union party saying her party was ready to form an administration. sport now...and for a full round up, from the bbc sport centre, here's jessica. football's world cup qualifiers continued this weekend, with many of the home nations in action. scotland are up against slovenia in what is a must—win game if they're to have any hope of reaching next year's tournament. manager gordon strachan has been under increasing pressure, with scotland managing just four points from theirfour qualifiers so far... it was almost a perfect start for scotland, but it's not grasp's corner was met. he did have the ball

in the back of the net but it was ruled out for pushing. a good start from scotland but no goals to show for it currently 0—0 hampden park. northern ireland have got off to a fantastic start against norway in the their group c qualifier. they are too— to up. connor washington has just scored they are too— to up. connor washington hasjust scored in they are too— to up. connor washington has just scored in the last two minutes. jamie ward opened the scoring in belfast afterjust 90 seconds! for england, they enjoyed a comfortable 2—0 win over lithuania. jermain defore, on his first appearance for his country since november 2013, got himself on the scoresheet. andy swiss was watching at wembley. a day to put football firmly in perspective. armed police on duty as wembley struck a poignant note. outside, the flags at half—mast, inside, the team is led out by five—year—old cancer patient bradley lowry before

a tribute to the victims of wednesday's terror attack, wreaths laid in the centre circle as 80,000 fans fell silent. the match itself seemed straightforward for england, it certainly began that way. the recalljermain defoe slotting them ahead. although an error from keeper joe hart nearly gifted lithuania and equaliser, england were in control at the break. after it, they struggled for fluency at first, but eventually they founded. substitute jamie va rdy keeping his cool to extend england's advantage. it was a ref highlight of a hundred victory. this was the subject performance from england but one that keep them on course for the next world cup. to women's football, where fa cup holders

arsenal ladies have been knocked out of the competition, after losing to birmingham i—0 in the quarterfinals. elsewhere, chelsea beat sunderland 5—1, liverpool were 2—0 winners at home to notts county, and manchester city got a last minute 2—1 win against bristol city. the draw for the semi—finals will take place live on bbc radio 5live at quarter to 3 tomorrow. ferarri's sebastian vettel has won the first formula one grand prix of the season, beating lewis hamilton in to second place in australia. it's vettel‘s first win since the singapore gp in september 2015, more evidence perhaps of mercedes' domination being over, after the introduction of faster cars. hamilton started in pole, but vettel had an advantage on pace and tyre wear, and took control after hamilton got stuck behind max verstappen after a pit stop. hamilton's new team—mate valterri bottas came 3rd. tennis, and british number onejohanna konta eased past pauline parmentia of france in straight sets in the third round at the miami 0pen. konta needed all three sets to win in the previous round but the world number 11 looked sharper in this match, she got the first break and went

on to take the first set 6—4. konta came flying out of the blocks in the second, taking two early breaks. she was in no mood to hang around, claiming the set 6—0, it took herjust over an hour to dispatch parmentia. up next for konta is either madison keys or lara arruabarrena in the round of 16. at the wgc matchplay semi—finals, world number one dustin johnson dustinjohnson is dustin johnson is through dustinjohnson is through to the final of the wgc matchplay. he beat tanihara. the tournament is one of the final offence, of course, before next month's masters. and that is it for now but i will have more sport for now but i will have more sport for you in the next hour. jeremy corbyn has said he'll oppose the government's plans to change european laws without full parliamentary scrutiny

when they become part of uk law during the brexit process. the government wants to include the powers in its great repeal bill more details will be published later this week. 0ur political correspondent alex forsyth has the story. we are europe! some still might not want it, but brexit is beckoning. the majority voted, and the government is about to start the formal process. parliament will see the historic moment this week, followed by details of the government's plan to give control over uk laws to westminster instead of brussels. some warn, as this complex work begins, mps must be involved. we're not going to sit there and hand over powers to this government to override parliament, override democracy and just set down a series of diktats, what's going to happen in the future. so what does the government plan? it will introduce a great repeal bill, bringing eu regulations into domestic law — everything from environmental legislation to workers' rights. then the regulations can be changed or abolished after brexit to suit the uk.

the bill will also include powers for the government to amend some eu laws during the process, without full parliamentary scrutiny. the government has already faced battles over parliament's role in the brexit process, and a great repeal bill looks like it could be the next big skirmish. some mps and peers fear they'll be cut out of key decisions. the government insists they will have a say and says major policy changes, like new immigration or customs controls, will be subject to full scrutiny. but ministers say there must be a way of making small technical tweaks, like unpicking some of the eu terminology. it will a limited and defined power, not to act like a dictator, by secondary legislation, and the scope, the scope, the definition of those powers and when they can be used, in what circumstances, is something that parliament will have to approve in boating through the bill itself.

—— in voting through the bill itself. but some resistance is likely. the sheer complexity of brexit means very little will be plain sailing. alex forsyth, bbc news, westminster. russian police have arrested more than 700 people in moscow after thousands took to streets to protest against corruption the opposition leader alexei navalny — is among those detained. people joined the rallies all over the country defying bans to stage marches. today's demonstrations are thought to be the biggest anti—government protests in five years. 0ur moscow correspondent steve rosenberg gave us this update from the protests. here an pushed in square in the centre of moscow the crowd is chanting quote we russia." . the russian authorities say that this anti—corruption russian authorities say that this anti—corru ption protests russian authorities say that this anti—corruption protests is illegal, but people in command of the street anyway. there is a heavy police

protest. 0ne anyway. there is a heavy police protest. one man tried it and fell an anti—putin on the statue. protest. one man tried it and fell an anti-putin on the statue. the level of corruption is too high in russia right now and every thinking citizen understands that. it is hard to live in a corrupt atmosphere, i have children, grandchildren and i cannot breathe in this. so now the white police have moved on to pushkin square, the police have been telling the crowd all afternoon that this is an illegal meeting. —— the riot police. it looks like the police ten currie intend to clear the whole square of protesters. —— intent to clear the whole square. we are told that the man who called people onto the street in monks go today and across russia has been detained. —— not only on the street

in moscow today. the bright police have now cleared protesters from the square and they are lined up all the way down to the main street here in the russian capital. people came out in moscow today to protest against corruption in the russian government, but this sends a message to the crowd, that is fighting corruption is not a priority for the russian authorities. the first dinosaurs may have originated in the northern hemisphere— and could even have lived in the area that's now britain. that's just one of the findings in a new study published in thejournal nature, which suggests that theories about dinosaurs that have been around for over a hundred years could actually be wrong. 0ur science correspondent pallab ghosh has more. fossilised bones that capture a time that dinosaurs ruled the earth, more than 65 million years ago.

by measuring how they changed over the years, researchers worked out how they are related, and how they evolved. but a new reassessment published in thejournal nature, which suggests that that theory which has lasted 130 years, may be wrong. the current theory is that there are two main groups of dinosaurs. one, which includes the stegosaurus, and another, which has two branches. the vegetarians such as the brontosaurus, and the meat eaters, such as the savage tyrannosaurus rex. it turns out that the meat eaters are in the wrong group, and should be with the stegosaurus. it also shows that the very first dinosaurs did not originate in what is now east africa, but much further north, possibly in an area which is now britain. we've taken dinosaur origins, which originally were thought to be southern hemisphere, and brought them into the northern hemisphere, and it could well be that dinosaurs originated even within britain itself.

what we have here is a key specimen in this analysis. and here is the fossil that led to this shock finding — a primitive dinosaur the size of a cat was found in lossiemouth in scotland. it was an animal like this that led to the creatures that dominated this planet for 165 million years. the new family tree will mean that we will have to rethink our ideas of how they evolved and spread across the globe. this is a fairly major change to our knowledge of dinosaurs. we have had a system in place for 130 years, we thought we understood the relationships of these big groups of animals, but it may be that we have a major rearrangement of the dinosaur tree. this re—evaluation of fossils challenges a theory that has been accepted since the victorian era, and so will be controversial. but if it is proved to be correct, textbooks on the subject
