leaders are starting to arrive at the conference centre here in rio dejaneiro, where the war in ukraine but also issues like tackling global poverty and climate change will be on the agenda. these are pictures from geneva, where the united nations relief and works agency chief philippe lazzarini is expected to react to israel's ban of unrwa in gaza. he has said that what is happening in gaza is an unrelenting horror. hello, i'm lucy hockings. welcome to bbc news now, three hours of fast—moving news, interviews and reaction. leaders of the world's 20 most powerful nations are gathering in brazilfor a summit, set to be dominated by the conficts in ukraine and the middle east and the imminent return to the white house of donald trump.

this is the scene live in rio dejaneiro, where brazil's president, lula da silva, is due to formally open the two—day summit with a speech shortly. we'll bring you that live. it is an incredible cast of people attending. among those attending, the us and chinese presidents, joe biden and xijinping, along with the leaders of britain, australia, france, germany, india, japan, saudi arabia and other countries. they are all there in a lovely day in rio dejaneiro and have been arriving in the last few hours and will continue to do so. the summit comes hours after the kremlin accused the outgoing us administration of wanting to "add fuel to the fire and escalate the conflict in ukraine", afterjoe biden gave the green light for kyiv to use us—made long—range missiles to strike deep inside russia. it means ukraine can now use army tactical missile systems, known as atacms, to defend its forces in russia's kursk region, on ukraine's

north—east border. washington had previously refused to allow such strikes with atacms missiles because it feared they would escalate the war. the major policy reversal comes two months before mr biden hands over power to donald trump, whose election has raised fears over the future of us support for kyiv. our diplomatic correspondent paul adams — who's in ukraine — explains what the missiles might be used for. what we don't know are the specifics of this. we understand that this will be used initially in aid of ukrainian forces who are currently operating inside russia, in the area of russian territory in kursk that they've been holding since august. that is important for them because they are anticipating a russian counteroffensive in kursk, assisted by as many as 10,000 north korean troops any day now. and so the arrival or the ability to use

the atacm missiles to complicate russia's planning will be important to the ukrainians. whether they are granted the permission to use it more widely in the future, well, we'll have to see. we don't know how many of these systems they have, and we also don't know exactly what the americans are saying in terms of what they can and can't do with them. it is also possible that britain and france may follow washington's lead and grant permission for ukraine to use the storm shadow missile, also to hit targets deep inside russia. none of these things, in and of themselves, can be regarded as game—changers. they're not necessarily going to change the course of the war in any emphatic way. but i think ukrainian officials believe that it is a necessary step, and one that will somewhat redress the balance of military might at a time when they really feel they're on the receiving end of a slow, grinding russian advance in the east, and a feeling that ukraine for the last several months

has really been on the back foot. that was paul adams there in ukraine. let's take a closer look at what both atacms and anglo—french storm shadow missiles offer ukraine. manufactured by lockheed martin, the atacm is a ballistic missile designed to be launched from a multiple—launch rocket system to hit key targets far behind the front lines, like ammunition stores, headquarters, and troop build—ups. travelling at supersonic speeds, it is capable of striking locations up to 300km away and packs a 227kg explosive warhead, or cluster munitions which open above a target to scatter hundreds of bomblets over a wide area. storm shadow is an anglo—french cruise missile with a maximum range of around 250km. the french call it scalp. it is launched from aircraft, then flies at close

to the speed of sound, hugging the terrain, before dropping down and detonating its high—explosive warhead. storm shadow is considered an ideal weapon for penetrating hardened bunkers and ammunition stores, such as those used by russia in its war against ukraine. both the uk and france had held back from authorising the use of the missiles inside russia without american approval for atacms. but the french foreign minister has today said paris remains open to allowing ukraine to use french long—range missiles to strike targets on russian territory. let's speak now to lord peter ricketts, former uk national security advisor and former ambassador to france. it is always good to have you with us on bbc news. i wonder if you think it is time for the uk and france to allow storm shadow to also be used within russia? , . ., , ., ., russia? yes, i certainly do and i think it is _ russia? yes, i certainly do and i think it is a — russia? yes, i certainly do and i think it is a welcome - russia? yes, i certainly do and i think it is a welcome step - i think it is a welcome step thatjoe biden has taken and i think it is part of his legacy,

he wants to give ukraine the maximum help in the weeks that remain for him by allowing them to use these much more powerful missiles which, as you say, complicate russia's decision making, instead of russia being a sanctuary where it can strike ukraine whenever and whether it likes, using north korean missiles and iranians drones, they now have to factor in that ukraine may be able to strike these high—value targets further from the front line and it is time that the uk and france say the same thing, there are far fewer of our storm shadow missiles in ukraine, the us has far more, but it would be a symbolic gesture is well up for the uk and france to stand shoulder to shoulder and give ukraine this much needed extra capacity to hold russian assets at risk. to clarify for our audience, france has said they are open to that option and we are waiting to hear from the uk to that option and we are waiting to hearfrom the uk on it. we have heard from russia today saying, this move froze

oil on the fire. do you think that this dangerously escalates things? that this dangerously escalates thin . s? . , ., that this dangerously escalates thins? . , ., ., things? -- at this move froze oil on the _ things? -- at this move froze oil on the fire. _ things? -- at this move froze oil on the fire. no, _ things? -- at this move froze oil on the fire. no, i - things? -- at this move froze oil on the fire. no, ithink- oil on the fire. no, i think you would expect russia to say that and they have been trying to deter western leaders from taking this decision and what has thrown oil on the fire has in the escalation for three years now and the completely unprovoked attacks we saw on the weekend on the ukrainian energy terrorism, to deprive ukrainian hospitals, schools, old people's homes of power, thatis old people's homes of power, that is pouring oil on the fire. this is giving the ukrainian people and legitimate right to defend themselves, and it will be them using the weapons, not to the us, uk or france and i don't think there is realistically more escalation that vladimir putin can do so this is sabre rattling on his part to try to deter western leaders from taking these decisions. we will
