strikes on kyiv overnight in what officials say appear to be the largest drone attack on the ukrainian capital since the start of the war. britain's government is discussing plans for supermarkets to cap the price of basic food items to help tackle the rising cost—of—living crisis. now on bbc news, sudan fighting: caught in the shrapnel. gunfire. it's mid—april. as violence breaks out in sudan, disturbing images of possible war crimes are emerging, being carried out on medical facilities and staff by both sides. the warring factions of formerly allied militia empty the streets of the capital. we wanted our contact on the ground to verify what's going on, but it's impossible.

using satellite data and mapping tools, we analysed user—generated content on a huge scale and spoke to dozens of doctors to build a picture of whether war crimes are being committed and the impact this is having on millions of people. so how did this conflict begin? on the one side, there's the government sudanese army often referred to as the saf, led by this man, general fattah al—burhan. opposing him is general mohamed dagalo hemeti, who runs the rapid support force, or rsf.

the two forces were due to merge, but when talks between them broke down, a bloody fight began, leaving civilians caught in the shrapnel. reporter fateh al rahman al hamdani lives by the international airport right at the heart of the fighting. but it's hard to reach him, so he sends us videos when he can. distant gunfire.

and here is why. this is one of khartoum's main water treatment plants. on the first day of fighting, it was hit. using satellite imagery, we can see the damage. in this image in 2022 the tanks are full, but here, only days after being bombed, they're almost empty. just across the river from the water plant, living opposite the british embassy, is british citizen and london hotel owner, 85—year—old abdalla sholgami and his wife, alaweya rishwan. their granddaughter azhaar has been trying to reach them from her home in new york.

that area, you can't leave. a child got shot in front of my grandparents�* house. there's snipers everywhere in that area. on april 25th, british nationals began to be evacuated from sudan. they were asked to make their way to an airport 25 miles from khartoum, crossing a war zone. azhaar�*s uncle and cousin called the foreign office helpline for assistance. my mother is 80. to get her to the wheelchair, it needs sometimes three or four people. we do need to stress- that there is no way for them to leave their location. the person they spoke to sympathised with the family, but the embassy couldn't help them. trapped in their home for days, with no food and water, azhaar�*s grandfather leaves his home to try and get help. five minutes into his journey, he got shot. three bullets, his hand,

chest, lower back. then we lost touch because no electricity and we didn't have a way to call them. and by that time, my grandmother was already alone for five days or so. alone, disabled, no food, no water. the last time we spoke to my grandmother, she was telling us that the rsf is raiding the house. wounded on the streets of khartoum, azhaar�*s grandfather desperately searched for a hospital, but this wasn't easy. hospitals were now shutting down. at the start of the conflict, there were 88 hospitals operating around khartoum.

by the 20th of may, 61 had closed. some had been bombed. one of the first is ibn sina hospital. dr awad is a surgeon there. we investigated. this picture of the hospital matches this image showing the damage from the attack. a forensic weapons expert told us it was most likely caused by artillery fire. there are also videos of a fire at the nurse's accommodation seen here behind this distinctive building. we can see the nurses�* accommodation

on the satellite image. in this later one, they've been damaged. we can't be certain who was responsible or if this was a deliberate attack. the fact that there was no warning given prior to, prior to a strike may well constitute a war crime. we took our evidence to dr christian de vos and dr houssam al—nahhas, international criminal law experts from physicians for human rights. there was patients receiving care. there was health care providers providing health care. there was patients receiving care. there was health care providers providing health care. the destruction within the facility is clear. 15 people were reported injured in this attack. even if it wasn't an intentional attack on the hospital, the fact that a bomb or mortar shell can then damage the hospital so severely and the patients inside does raise questions again about adherence

to the laws of war. gunfire.

from thousands of miles away, azhaar was aware her grandmother was living the same reality. she was desperate to save her. we've seen emails between azhaar�*s family and the british ambassador in sudan. they point out her grandfather is british and they've been trapped for weeks without food or water. the ambassador responds. with the embassy now closed, there's little they can do. he promises the embassy will be in touch, but no—one contacts them. azhaar hadn't heard from her grandparents for five days. then she received a call.

it was one of the diplomats in the turkish embassy. and then he goes off to say that, i'm sorry to tell you this, but we went inside and your grandmother passed away. i'm so sorry. that's so heartbreaking. and they were physically just across the road from the british embassy, right? maximum, four steps away. maximum. and itjust breaks my heart to think that she died alone and she died because she was alone. and she's still alone to this very moment. and she might be buried alone, none of herfamily members around her. and i'm sure yourfamily did everything they could to try and get them out. everything. what happened to my grandparents was a crime against humanity, not only by the rcf, not only by the saf, but by the british embassy, because they were the only ones that could have prevented this from happening to my grandparents.

two weeks into the war, east nile hospital was one of the last operating in the area. reports started emerging of patients

being forced out from the building. the rsf had surrounded it with their vehicles and anti—aircraft weapons. on may 1st, a public area next to the hospital was hit by an air strike. the army are the only ones with such capability. our sources tell us there was no warning and that doctors were treating civilians and rsf soldiers at the time. the duty to warn of any impending air strike and to ensure take due precaution that all civilians are able to evacuate the hospital prior to an air strike. that is very clear under the laws of war.

five people were reportedly killed. two weeks later, the hospital was hit by another air strike.

throughout the conflict, there have been allegations of rsf soldiers taking over hospitals. this video shows them entering a hospital. and here inside the hospital, we see soldiers outnumbering civilians. the world health organization has reported nine confirmed cases of hospitals being taken over by the warring parties. i think it's important to note that by providing medical care to soldiers in the context of conflict, that is not itself a violation of the law of war. i think the question that some of the video raises is both

the preferential treatment potentially between civilians and soldiers. that is not an appropriate use of a medical facility and may well constitute a violation of the laws of war. but it doesn't end there. doctors are also being targeted. we've seen messages widely circulated on social media, threatening doctors by name, even sharing their id number. they accuse them of supporting the rsf and receiving money from abroad. two doctors told us they've had to go into hiding. one of them spoke to us but wanted to remain anonymous. doctors treat whoever comes to them in these hospitals,

but in spite of this, they've received many threats, death threats from the remnants of the previous regime. they accuse them of supporting the rsf. because of these threats, doctors have had to stay away from these hospitals and have had to go into hiding. sudanese doctors�* organisations have been monitoring threats, which they say are coming from both sides. another potential war crime. for weeks, we've been trying to put our allegations to both parties. i asked mostafa mohamed ibrahim from the rapid support forces about the targeting of hospitals and evidence of possible war crimes.

we repeatedly tried to speak to the sudanese army but they didn't respond.

he's not answering. azhaar is still trying to get her family out of sudan. and that was the one bus driver that's supposed to be taking my family tomorrow. azhaar�*s family hasn't been able to tell her grandfather that his wife has died. we still were all kind of confused on how to tell him this. he put on his clothes and he was very kind of irritated. and he started asking my dad for his keys, his house keys, his car keys. and he said, "if you're not going to give me, i'm going to go walk back home." because he wanted to check up on my grandmother. could the british embassy have saved her grandmother's life had they been more responsive to azhaar�*s family's pleas? i was informed they got 100 troops

who came and evacuated their staff. they could not cross the road. i'm so very disappointed in them, in giles lever, the ambassador, the british ambassador in sudan. until now, there's no call, no initiative. they don't know how my grandparents are. my grandfather is. we asked the foreign office why they couldn't do more to help azhaar�*s grandparents. they told us... doctors around the world have been calling for an end to the targeting of medics in sudan. at this conference in london, doctors have already begun the process of trying to document possible war crimes.

when war crimes become a tactic of war, literally, people will no longer seek care and will be deprived of their right of access to health care. we do not want sudan to become another situation where people are not seeking care because attacking hospitals is a war strategy. even though multiple ceasefires have been promised, the fighting in sudan hasn't stopped and hospitals are still being targeted. many thousands have decided the only solution is to leave.

hello there. let's take a look at the weather for the week ahead. high pressure remains dominant as we head through next week so for the foreseeable future, it is certainly looking dry and settled, there could start to be a few changes by next weekend but for the rest of this bank holiday weekend, it is set to stay dry for the vast majority of us. there will also be some warm spells of sunshine, the cloud and the sunshine amounts will vary day on day. high pressure out towards the west on sunday and there is a very weak

cold frontjust sinking southwards across england throughout the day, introducing cloudy conditions but no rain on this. for most of us, it is going to be a cloudier day than on saturday. the cloud will break up across northern ireland, though, as we head through the afternoon. still cloudy conditions across western scotland, brighter further east but here it's cooler than on saturday. the best of the sunshine on sunday for western wales and for the far south—west of england, devon and cornwall, where temperatures could peak at 23 celsius. now, as we head through sunday and into monday, you can see that colder airjust gradually filtering down from the north, so across it is a cooler—feeling day really on monday, and it is squeezing the isobars across the south of england, too, so here it is going to feel really quite windy, cold winds for north sea facing coasts with plenty of cloud, blustery conditions for channel coasts, particularly windy across the channel islands. but there will also be some some sunshine for the south coast, the cloud will break up

across east anglia as well, so some sunny spells emerging, dry with the best of the sunshine and probably the highest temperatures across northern ireland and across the central belt of scotland, maybe 2i celsius on monday. now, as we head through the rest of the week, the high pressure is going nowhere. in fact, it is continuing to build in so it is set to stay dry and settled but we've still got that onshore breeze towards eastern coastal areas of england, and here the wind is going to feel quite brisk at times. it is always going to feel cooler towards the coast. some of these clouds could produce a few spots of drizzle from the thickness of it, maybe, but generally speaking it should stay dry again. as you can see, the best of the sunshine always the further west you are, across wales, the south—west of england, northern ireland, and for much of scotland the sunshine is set to continue through the middle of the week, maybe 2a celsius on tuesday. and it is looking really very similar on wednesday, too, some areas of cloud, thickest out towards parts of east anglia, an onshore breeze for eastern coastal areas, sunshine, the highest temperatures further west again, 2a celsius expected in south—west scotland, don't forget the uv levels will be high and the sunshine strong at this time of year.

also, the grass pollen season just getting under way. a few changes as we head through the middle of next week in that the high pressure is expected to move off towards the north and the west. so the focus for the eastern coastal winds will really be across north—east england and perhaps eastern scotland, just driving some cloud onshore at times, some slightly warmer air coming round on this area of high pressure into southern areas of england and wales. we could see 23 or 2a degrees celsius maybe in london and cardiff on thursday afternoon, so temperatures starting to recover here, possibly the warmest day of the week. as we look ahead into the outlook for friday and the weekend, some of these showers across europe could maybe move a little bit further northwards as the high tends to pull away. a couple of the models are suggesting this but it is a bit more likely at the moment that it will stay dry and settled and that the sunshine will tend to continue. it could turn cooler by the end of the weekend and into the start of next week, but do keep checking the forecast. at the moment, it is still a long way off. bye—bye for now.
