gordon corera, thank you.north america editor sarah smith in a moment but first chris mason is at the white house for us. chris, given the mood music, what do you expect to emerge from these talks? ~ , ., , talks? well, there is a broader canvas beyond _ talks? well, there is a broader canvas beyond the _ talks? well, there is a broader i canvas beyond the conversation, talks? well, there is a broader - canvas beyond the conversation, the specific conversation about ukraine andindeed specific conversation about ukraine and indeed about this dilemma over missiles. talking about the middle east and china, for instance. you get some sense of the urgency from downing street's perspective of some of those items on the agenda, not least that missile question, that they want to come here and talk to a president who is out of power in a matter of months, so they know there are decisions in the works that they believe need to be taken in the coming weeks and on the question of missiles, we do seem to be edging towards

tonight, our security correspondent, gordon corera, looks at this new form of technological warfare.our international editorjeremy bowen, amid grave fears this is about to escalate across the middle east. today a division of the israeli army has relocated from gaza to the north of israel, reinforcing troops there. let's go straight to beirut and our senior international correspondent, orla guerin. tonight we are in new territory. this is a new phase of the war. israel says so hezbollah classed as a terrorist organisation by the uk and us is also saying the same. here in beirut in the hezbollah stronghold, we saw fear and chaos and panic when reports started coming in of a second wave of explosions, casualties were being rushed away for treatment. one young member of hezbollah said this was a terrible time for us, we have never seen anything like it, we are encouraging our supporters to go home to try to stay safe. in the past 2a hours hezbollah�*s communication networks have been shattered by israel but it would be a mistake to say the organisation is defeated. farfrom it. it is prom

0ur security correspondent gordon corera has been investigating.he afternoon when something extraordinary happens in lebanon: explosions in people's pockets. so how did it happen? it appears that what was blowing up were these — pagers, older devices which can receive text messages. this is believed to be one of the models targeted. this is the militant group hezbollah — this summer it was reported to have given orders for its men to switch away from mobile phones because it feared they could be tracked and calls intercepted. instead they were told to use pagers — as they believed it offered more security. but that decision appears to have been exploited to target them. this is thought to be one of the pagers that blew up today. but how was it detonated? a cyber attack — hacking into them remotely to make them overheat — would not make them explode in the way seen today. more likely is that the pagers destined for hezbollah were physically intercepted and had small amounts of high explosive — maybe just a few grams — planted inside ready to be deto

attacks have stunned people in lebanon and caused widespread fear. 0ur security correspondent, gordon coreras have been carried out in the past 2a hours and who's orchestrating them. these have been extraordinary attacks — taking communications devices people carry around and turning them into weapons to be used against them. today, hand—held radios, walkie talkies, were exploding suddenly in lebanon. this was what was left of one of them. it follows yesterday afternoon when thousands were injured by small explosions in people's hands and pockets. this was the culprit — a pager, which can receive text messages. pagers and walkie talkies are old school technology, but something hezbollah turned to recently because it feared its mobile phones could be tracked. this map details the locations of injuries sustained in yesterday's attack, the vast majority in the capital, beirut. but how was it done? today, washington said it didn't know. the united states did not know about, nor was it involved in these incidents. and we're still gathering the information and gathering the facts. so what do we kn

our security correspondent gordon corera explains why. the western weapons at the heart of today's debate. they include american atacms and this, the british storm shadow system, which has a range of at least 250 kilometres. storm shadow has already been used by ukraine against a russian base in occupied crimea last year, but up until now the countries supplying these weapons have told ukraine it can't fire them into russia, but there's been pressure for that to change. the reason is that russia has been making advances on the front line inside ukraine. it's been hitting ukrainian positions using glide bombs, and its forces have been supported from over the border, inside russia. what ukraine wants to be able to do is use the longer range of the western missiles to strike deeper into russia, targeting the command centres and ammunition depots supporting moscow's advance. so, what are the risks? vladimir putin says ukraine using these weapons inside russia would be an escalation, claiming they require western assistance and meaning nato co

with me is our security correspondent, gordon corera. first of all, let's talk about the intelligence aspect, from israel's point of view they seem to have had a string of stunning successes. where are they getting their intelligence from? it they getting their intelligence from? , ., ., from? it is a contrast to the lack of intelligence - from? it is a contrast to the lack of intelligence they - from? it is a contrast to the i lack of intelligence they had about hamas and its attacks near lay year ago. israel in 2006 invaded lebanon and got stuck and got caught by surprise. i think by the strength of resistance it faced from hezbollah. since then it has been working to build its intelligence collection capability on hezbollah very methodically and not underestimating its foe in a way it might have underestimated hamas. there has been a long—term collection, whether using satellites or human resources. it looks like being brought to bear now, whether it is something on like the pager attack and the attack on walkie—talkies, that was a lo
