after the westminster attack — the government steps up pressure on internet companies over access to encrypted messages. khalid masood is thought to have been using whatsapp moments before he killed four people — the home secretary says firms must act. the home secretary says 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. as the investigation continues, there's been another arrest — a 30—year old man from birmingham is being questioned. also tonight — after reports that an air strike against islamic state caused scores of civilian deaths in iraq, we'll have the latest from mosul. in iraq, we'll have among the casualties of the battle for the city — two young boys in this field hospital. most of those we've seen being brought in are children, they've been injured by air strikes, and also by shelling but the staff here tell us they also receive a lot of patients who've been shot by is snipers.

of patients who've been shot in moscow, hundreds of people are arrested after the biggest opposition rallies in russia for years. and england beat lithuania at wembley in their world cup qualifier. at wembley in their good evening. the home secretary, amber rudd, has increased pressure on internet companies in the wake of the westminster attack, warning them not to provide a secret place for terrorists to communicate. it's understood that khalid masood, who killed four people on wednesday, was using the secure whatsapp messaging service shortly before the attack began. messaging service shortly our security correspondent jonny dymond reports.

our jonny dymond reports. technology companies doin enough our technology companies doing enough to combat terrorism? that was the question raised today, especially when it comes to encrypted communications. coloured was active cannot pass on content of messages, because they do not have access to encrypted data. today, the home secretary said it was not good enough. we must make sure that organisations like whatsapp, there plenty of others like that, do not provide a secret place for terrorists to communicate with each other. it used to be that people would steam open envelopes or listen in on phones when they wanted to find out what people were doing legally, but we need to make sure that our intelligence services have the ability to get into situations like

encrypted whatsapp. police say they are worried that technology companies are designing systems that will not allow for traditional surveillance. at the heart of this is inconsistency between the ability of police to lawfully intercept telephone calls, but not when those m essa 9 es telephone calls, but not when those messages are exchanged via social media messaging boards, for example. that is an inconsistency in society, it surely is, we need a solution through appropriate legislation. but, encryption is getting more popular as it protects ordinary people's data from hackers and criminals, helping to preserve privacy. that makes some nervous about giving the state new powers to restrict it. they have huge powers of investigation already and there isa of investigation already and there is a question of always balancing the rights to know, the need to know, with the right to privacy. phones, as well as messages, can be in cryptic. after a terrorist attack in san bernardino, america, there was a row between apple and the fbi, who wanted a phone unlock.

we don't know for sure in this case of police could access masood's phone yet. it might help to once a whether he really did act alone, as police think. encryption is an issue law enforcement and the government have long worried about. in the coming week, technology companies will be meeting with officials from here, at the home office, in a previously scheduled meeting. but encryption is only one of the issueis but encryption is only one of the issue is whether government wants technology companies to do more. the wealth of extremist content posted on websites is a high priority for the government, which fears is radicalising effect. it wants companies to find the material themselves and take it down, rather than wait for it to be reported to them. there's no sign of new legislation in the wake of this attack. police have just legislation in the wake of this attack. police havejust got legislation in the wake of this attack. police have just got new powers over data, but authorities may be hoping that they can put enough pressure on technology companies to change their behaviour.

gordon corera, bbc news. there's been another arrest in connection with the investigation into attack, with a 30—year—old man from birmingham now being questioned. with a 30—year—old man from 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. information from people 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. in an attempt to discover 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 a violent past, when he may have adopted extreme political views, possibly while serving a prison sense in 2003, possibly while serving a prison sentence in 2003, or during two periods living in saudi arabia, or 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 can 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. tomorrow's potential terrorists birmingham tomorrow's potential terrorists remains a focus in1 investigation, birmingham remains a focus in this investigation, the last place where masood lived. the man who has been arrested, a 30—year—old, in birmingham, he is being questioned on suspicion of preparing for terror acts. the 58—year—old man arrested days ago is still questioned in custody and a 32—year—old woman, released from custody on bail. most of the searching of addresses going on is coming to an end but i think this really is the end of the beginning. studio: tom symons, thank you.

iraqi forces are intensifying their assault against so called islamic state, as they attempt to drive them out of western mosul. thousands of people have fled the city in recent weeks, and there are conflicting reports about who was responsible for scores of civilian deaths in a single incident last week. the us says it's investigating but has stopped short of taking responsibility. but has stopped short with the city still divided between is and the iraqi army, our correspondent orla guerin has been to a field hospital in the south of mosul. been to a field hospital ii—years—old, shot in the leg. been to a field hospital behind him, a boy of the same age, hit by a mortar. brought together in a field hospital by acts of war. these boys, children of mosul. hospital by acts of war. not safe at home, not safe when they flee. the beds are filling up here. safe when they flee. ambulances have been arriving every few minutes.

most of those we've seen being brought in are children. they've been injured by air strikes and also shelling, but the staff here tell us they've also received a lot of patients who have been shot by is snipers. a lot of patients who have been shot it is shoot to kill. a lot of patients who have been shot isis is not messing around. a lot of patients who have been shot they don't want people to leave, and they don't care whether it is a child, man or an old woman. everybody is being shot as they try to escape. people are saying it takes two isis militants to really keep an area under control, and prevent civilians from going anywhere. they want the civilians to stay inside to remain as human shields. to stay inside to remain this man tried to break free with his younger brother, but his brother was targeted by an is sniper. this footage filmed by hospital staff shows the anguish of abdullah. his five—year—old granddaughter, sara, is in the body bag. is shot her through the heart.

sara, is in the body bag. but those who escaped the battlefield are bringing accounts of other innocent civilians. allegedly killed by their liberators. victims of bombing raids, by iraqi and coalitionjets. akram mahmood insists that his brother was one of them. on the right, he says that his brother was a truck driver, and not a militant, and his guide all his life. hamad died on his own doorstep, he tells me. an air strike hit his car. doorstep, he tells me. five men were killed with my brother, he says. i bury them with my own hands. with my brother, he says. the slogan from the authorities was "we are coming to rescue you,

to free you from is". in reality, my brother has been killed, and lots of families have been destroyed. killed, and lots of families and in the camp nearby, the broken and the displaced reach out in desperation. the broken and the displaced after yea rs of is tyranny, and months of warfare, one more hardship for the people of mosul. orla guerin, bbc news, northern iraq. talks in northern ireland about forming a new power—sharing government have collapsed, just ahead of a tomorrow afternoon's deadline for a deal. just ahead of a tomorrow afternoon's this evening, sinn fein walked out of negotiations saying they had come to the end of the road, raising the possibility of yet another election. raising the possibility our ireland correspondent chris buckler is in belfast... what buckler is in belfast... is the most likely outcome? technically, what is the most likely outcome? technically, tomorrow the storm on

to send a supposed to meet by 4pm to elected deputy first minister, but sinn fein made that clear that was not going to happen. they are left with two options, to hold another election, the third injust with two options, to hold another election, the third in just over a year here, all tentatively, they could put in place direct rule, where westminster takes over the running of northern ireland for a period. but i think short term, they will delay decisions and play for time which has practical consequences, not least when it comes to budgets. it will leave doubts over spending, in terms of public money for the next while, and thatis public money for the next while, and that is a real concern. in the last few days, the northern ireland secretary james brokenshire has sounded optimistic, saying a deal was possible by tomorrow but practically tonight, it seems there is little basis for that optimism. the dup and sinn fein are as far apart so other parties have suggested these talks have gone nowhere, and now he and theresa may face the reality that there is a

real crisis at stormont and have to consider the possibility another election, after what was a pretty divisive vote earlier this month, could lead to problems becoming worse rather than better. chris buckler in belfast, thank you. the head of britain's biggest union — unite — has said thatjeremy corbyn should be given 15 months to see if he can improve labour's poll ratings. be given 15 months to see if he can len mccluskey is standing for re—election as the union's general secretary. for re—election as the union's mr corbyn says labour is ready for a general election if one is called. is ready for a general meanwhile, mr corbyn‘s said he'll oppose the government's plans to change european laws without full parliamentary scrutiny when they become part of uk law because of brexit. the government wants to include the powers in its great repeal bill, more details will be published later this week. more details will be our political correspondent alex forsyth has the story. some still might not want it, but brexit is beckoning. the majority voted, and the government is about

to start a formal process. and the government is about 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. to give control over uk laws to some warn as this complex work begins, mps must be involved. we are 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 of what is going to happen in future. a series of diktats of what is going so what does the government plan? a series of diktats of what is going it will introduce a great repeal bill, bringing eu regulations into domestic law. everything from environmental legislation to workers' rights. legislation to then, regulations can be changed or abolished after brexit to suit the uk. changed or abolished after the bill will also include powers for the government to amend some eu laws during the process, without full parliamentary scrutiny. during the process, without full the government has already faced battles over pa rliament‘s role in the brexit process,

and the great repeal bill in the brexit process, looks like it could be the next big skirmish. some mps and peers fear that they could be cut out of key decisions. that they could be cut out of key the government insists that they will have a say and says major policy changes, like new immigration or customs controls, like new immigration will be subject to full scrutiny. like new immigration the ministers say that they do need the power to make small, technical tweaks, like unpicking some of the eu terminology. it will be a limited and defined power. not to act like a dictator, but by secondary legislation. but by secondary right... but by secondary and the scope, the definition of those powers and when they can be used in what circumstances, that is something parliament will have to approve in voting through the bill itself. some resistance to the bill is likely, the sheer complexity of brexit means very little will be plain sailing. tonight, very little will be plain sailing. as the government j

to tonight, as the government prepares to launch the formal process of leaving the interstate a few days' time, there is another warning from the european commission chief negotiator about the consequences of failing to reach an agreement on the terms of brexit. the government has said it is confident of getting a good deal, there's inevitable positioning on both sides but one thing on which they agree is that this will be a hugely significant negotiation, not just this will be a hugely significant negotiation, notjust for the uk, but for the eu too. alex forsyth, thank you. thousands of russians have joined rallies in cities across the country to protest against corruption and call for the resignation of the prime minister, dmitry medvedev. and call for the resignation of several and call for the resignation of hundred demonstrati arrested several hundred demonstrators were arrested by police in moscow, including the opposition leader, alexei navalny. the kremlin has not commented on the demonstrations. our moscow correspondent, steve rosenberg, sent this report. there were moments today when moscow resembled a battlefield. russian riot police broke up an anti—government protest, on what was a day of demonstrations

across russia. across in moscow, they detained more than 500 people. earlier, police had poured into the city centre, warning that the protest was illegal. still, thousands of people packed into pushkin square, accusing the russian government of corruption. the level of corruption is too high in russia right now. every single citizen understands it. in russia right now. it is hard to live in a corrupt atmosphere. i have children, grandchildren, and i cannot breathe in this. and i cannot breathe these people have come out to protest against government corruption, but the message which this is sending to the crowd is that fighting corruption is not a priority of the russian authorities. a among those arrested, russian opposition leader alexei navalny. russian opposition leader alexei

them the power to hack people's devices legally. it means they can ta ke devices legally. it means they can take over someone's device before it leaves the phone and becomes encrypted, it can be gathered and in fa ct encrypted, it can be gathered and in fact all the data on the phone can gathered. all of this, whatsapp, never used to being printed in this way. it is a reaction to the snowdon revelations and a reaction to this such a blessed nation that is coming. tech companies suffered reputational damage because it was found that their information was looking like a sieve, in reaction to that to reassure their users they said they would encrypted. how likely is it that a government could outlaw encryption? they can do it, then i phoned will be illegal and other security devices, the problem is that is even if the phones are rendered weak, it is still possible

for the parties to write software that will still encrypt, so the bad quys that will still encrypt, so the bad guys will still like that software and have it made in use it, so the only people that will lose the general public. the home secretary suggested that in the old days the intelligence services would listen in on phone calls or steam over terry open envelopes. how relevant the comparison is that? -- steam open envelopes. elizabeth is genuine, yes they could always listen in a telephone call or steam open a person's envelopes, but they never had the power to do, they say they want the same powers, but it is more than that because it allows them to and what security services has been doing is trawling everybody‘s data. they never had the power to open everyone's envelopes and listen to everyone's phone call. they had be selective and have a warrant. now it is possible for them

arresting that temperature. at maybe arresting that temperature. at maybe a touch code of last night across southern parts of the uk would like to rinse. what would the northwest we could see pictures below freezing. not as cold for northern ireland because more cloud arrived was the end of the night and it will soon warm up in the sunshine across mainland scotland. a different start of the day all the way from north—east in ling, parts of the midlands, eastwell ‘s work. grey. —— north east england. there also may be mist and fog. the greyness pixel out a lift, slowly we should see it improving in most areas. some stubborn areas of cloud will linger through the day. most of us will see some sunshine. around north sea coasts, notably north—east england, it could stay grey or cold, but would light winds we could get 17 or 18 degrees again across highland scotland. as we run through the rest of the week we will see more and more cloud. bringing some showers,
