israel says it's found a tunnel shaft inside al—shifa hospital, where it believes hamas has a command centre. the military has taken the bbc inside the hospital. they say among the things they've uncovered are more than a dozen kalashnikovs, grenades, personal protection equipment, some with the hamas military brigade insignia on it. israel also says it's recovered the body of one of the hostages kidnapped on october 7th. targeting a leading cause of drug deaths in america, we examine the deal betweenjoe biden and xijinping to curb the flow of sentinel into the us. fears that one of the richest ecosystems on earth is in crisis. how dams and climate

al—shifa hospital. they also found a tunnel shaft and a vehicle containing a large number of weapons at al—shifa hospital, as the military operation there continues. israel is under pressure to back up its allegation that al—shifa has been used by hamas for military purposes. we begin our coverage with this report from lucy williamson. this is what israel says hamas has been trying to hide. and where. the entrance of an underground work of tunnels they say uncovered today in the hospital grounds. israel wants to show that hamas is using this hospital as a military base, to explain why israel is too. this vehicle full of weapons was also discovered there today, the army said. israel's army has been keen to justify its military operation inside the shifa hospital.

last night, they took us in. we are inside the gaza strip with the israeli army. they are taking us to gaza city and the shifa hospital which, over the last few days of intense fighting, has emerged as the epicentre of this conflict. tonight they are offering us a first glimpse of what they found inside. israel's intense bombardment of gaza has meant growing pressure over the humanitarian cost of their military operation. we are driving into gaza city now and it is clear what it took to take control of this area. whole neighbourhoods have been completely shattered. there are columns of tanks moving through the streets here. the area around shifa is still very tense. we are taken into the hospital in darkness using a light—sensitive camera to film. just clambering through a collapsed wall here in the perimeter of the hospital. we are told to keep all our lights off so it is quite hard to see. they have used

armoured bulldozers to punch through here. we are still being told to keep our lights off. are we going this way? inside the hospital, we are shepherded straight to the mri department by israeli special forces. we are not allowed to talk to any doctors here. they have described the situation as catastrophic. now in control of the hospital, israel is under pressure to prove hamas is there. they've been looking for evidence of this being a hamas base. and they say that among the things they've uncovered are more than a dozen kalashnikovs, grenades, personal protective equipment, some of it with the hamas insignia, you can see it here hidden under bags of medical suppliers.

the army also showed us laptops they say contained recent files on the hostages and evidence that hamas had been at the hospital within weeks or days. it seems as if at this point neither the hostages nor hamas are here in any number. we will continue. hamas aren't here because they understood and saw that we're coming and i think had we taken them completely by surprise we would've seen mountains of evidence of hamas use of the hospital. tonight a hamas leader in lebanon denied the weapons found in al—shifa belong to the group. israel came to fight hamas in a place where civilians are fighting for their lives. the battle for shifa hospital is now the eye of the military offensive and gaza's humanitarian crisis. the and gaza's humanitarian crisis. israeli military are: inside the israeli military are still inside the hospital and the situation remains tense. it's very difficult to reach our team on the ground in gaza, but

this afternoon rushdi abualouf was able to send an update. all communication is down tonight in gaza and is going to be down for a long time because this time it's not by israel — it's because of the lack of fuel. getting the information is very difficult. the last call i made to our contact in shifa hospital, he was talking about tanks and hundreds of soldiers storming the hospital again, searching from room to room, calling on loudspeakers the people where to go out. he said they were shooting randomly onto the building, destroying many cars and also bulldozing some of the external wall to the hospital. he said tanks were inside the hospital and he was screaming on the phone, saying that this is maybe the last call. it's extremely difficult to contact people in the north, and in gaza city, and also communication among the people here — about a million people are displaced in the south of gaza tonight — is also difficult.

the un's world food programme says civilians in gaza are in a desperate situation. the executive director says: "with winter fast approaching, unsafe and overcrowded shelters, and the lack of clean water, civilians are facing the immediate possibility of starvation". let's turn away from the conflict in gaza for now and to san francisco. president biden met with xijinping san francisco. president biden met with xi jinping and says the us does not seek conflict with china, despite calling him a dictator. in a four hour in their four—hour meeting, the two sides agreed to restore military to military communications, and engage over artificial intelligence. president xi said china was ready to be a partner and friend of the united states.

ican i can certainly say there was a sigh of relief... my colleague relief... sumi somaskanda is in san francisco. i asked her about reaction in the us to the apparent thaw in relations. it's been welcomed here. i can certainly say there is a sigh of relief after seeing that meeting go off yesterday. the fact that us and china were able to sit together, these two presidents were able to sit at a table to talk through some of these thorny issues and establish a line of communication. we heard president biden reiterate the fact that military to military communication will resume. he told delegates, ceos in the room that is particularly important if there's another spike in tentions that it doesn't spiral into conflict. that is something that ceos, delegates here at the apec summit have welcomed for that and generally democrats welcomed. he has been criticised by republicans who have said that this meeting hasn't produced anything substantive and he should not be sitting down with president xi jinping in the first place. mostly this has been

a welcome sign. you mentioned that president biden after that meeting did call president xijinping a dictator again. that might�*ve had some in the white house shaking their heads after this carefully orchestrated meeting, a meeting that went fairly well. to be fair, we saw the chinese foreign minister respond, we haven't seen much coverage of that statement from president biden. all and all it seems that this meeting and the plan to bring the sides together to speak and make sure those lines of communication are open, that did go well. i was going to ask you about that dictator comment. communication has been welcomed. the fentanyl deal, some criticism it was lacking in more detail on how they were going to stem the flow. this agreement is simply that china has agreed to crack down

on some of the products that go into making fentanyl. it remains to be seen whether china will go forward and actually make that happen, implement that on china's side. we should say from president biden�*s perspective fentanyl is a big deal, despite that criticism it has been a huge problem in cities like san francisco where we are. we have welcomed the deal and said the fact that it's on paper is a good sign, let's see if it is implemented going forward. the rate of drug deaths from fentanyl trickled in the us until 2021. fentanyl trickled in the us until202i. more fentanyl trickled in the us until 2021. more are killed by drugs than vehicles on the road or in shootings, with more than 100,000 total overdose deaths in 2021. so can the agreement to curb illicit fentanyl production help and what is china's role in the epidemic? i

am joined by a senior fellow at brookings institution, director of the initiative on non—state armed actors. great to talk to you. can you give us some background on this problem? how did things get so bad in the us? ., ., , " ' i: , us? one originates in the 1990s when us pharmaceutical - when us pharmaceutical companies systematically lied to consumers and regulatory bodies, that prescription opioids such as 0xycontin were not addictive. this gets a vast amount of us people with substance misuse disorder, something an illegal market could never accomplish on this scale. the crisis becomes even far more severe when china starts... synthetic opioids such as fentanyl. ..

starts... synthetic opioids such as fentanyl... chinese traders start shipping it to the united states. within the context of this vast addiction, that generates this immense spike in lethality. it gets even more devastating as mexican cartels become the principal producers of fentanyl after 2019, principal producers of fentanyl after2019, using principal producers of fentanyl after 2019, using chemicals made in china, and start adding fentanyl into everything, fenta nyl into everything, cocaine, fentanyl into everything, cocaine, heroin, methamphetamine. and now it's even more complicated, because in addition to the mixture of drugs, we are also seeing an additional synthetic drug, another synthetic chemical produced in china, being added, further compounding the lethality and the morbidity of these drugs. 50 lethality and the morbidity of these druqs-_ lethality and the morbidity of these dwe— these drugs. so will this agreement _ these drugs. so will this agreement with - these drugs. so will this agreement with china i these drugs. so will this - agreement with china help? we know there is a massive pharmaceutical industry there, and the companies there are

fact, there is plenty of evidence that many are knowingly sold to mexican cartels, often with the rest of how to turn those drugs into fentanyl. what was accomplished at this summit is significant, china is once again promising it will start taking law enforcement actions. what is not known, but before even the announcement was made, china started taking some actions. we have seen enforcement, we have seen the chinese government distributing systematic messages to provinces saying they will be enforcing. that said, how long and how robustly remains to be seen. 50 said, how long and how robustly remains to be seen.— remains to be seen. so do you aet remains to be seen. so do you net the remains to be seen. so do you get the sense _ remains to be seen. so do you get the sense that _ remains to be seen. so do you get the sense that china - remains to be seen. so do you get the sense that china is - get the sense that china is willing to help with this issue? i willing to help with this issue? ~ ., willing to help with this issue? ~' ., , issue? i think china is willing to help right _ issue? i think china is willing to help right now. _ issue? i think china is willing to help right now. let's - to help right now. let's understand why that is the case. i think there are multiple motivations. a very important one is both china and the united states have been

looking for ways to stabilise the increasingly tense and hostile relationship. they have been essentially looking... inaudible. in what has become a new cold war between the two countries. this is not going to change, we are not going to be able to dial the clock back to 2010, 2005, to much warmer relations between the countries. but at least we have put a floor to the freefall. and co—operating on fentanyl was a very important element to achieve that stabilisation. second motivation for china is its image as the world's toughest drug cop was increasingly being exposed... we drug cop was increasingly being exposed- - -_ exposed... we have run out of time, exposed... we have run out of time. but _ exposed... we have run out of time, but fascinating - exposed... we have run out of time, but fascinating to - exposed... we have run out of time, but fascinating to talk i time, but fascinating to talk to you, thank you so much for

it's one of the richest ecosystems on earth, but there are fears the mekong river is in crisis. the waterway sustains more than 60 million lives, as it travels through china and southeast asia. but it is facing an onslaught of dam building, intensifying the effects of climate change and sand dredging. mi lives in a world of water that was once renowned for an abundance of fish. but in recent years, he and thousands like him have been asking, where are they? translation: these past few years, there is less and less i water and fewer and fewer fish go home. now we have children and every morning i need around $5 to get them to school. and these days, i have no income.

it has taken four or five days, and that's all i get. i have no fish to sell. since the 1990s, some countries have eyed the mekong river as a potentially powerful energy resource. china has built 11 dams on the mainstream. laos has two. dozens more are planned. experts who monitor water levels in the dams are worried. rainfall that typically would fall during the wet season is much lower than normal. but at the same time, upstream dams are restricting water. during that wet season, climate impacts and dam restrictions are changing the way that the mekong flows, much for the worse. studies suggest river nutrients and fish are now struggling to make it downstream. and when they do, they're struggling to survive. elsewhere, the mekong has other

gifts to give — sand. 60 million tons of sand is dredged from the mekong each year to help construct developing southeast asian cities. that's the equivalent of 950 0lympic sized swimming pools. this 25—year—old was jailed for more than a year for organising protests to protect the river. translation: when i see this, it makes me worry i about the mekong state and its impact on the cambodian about the mekong's fate and its impact on the cambodian people as a whole. the cambodian government has long been accused of profiting from plundering the country's natural resources, which it denies. it's the moment fans of "the crown" have been waiting for.

after a year—long wait, netflix has begun showing the first episodes of the final series of the royal drama. has the drama lost its gloss? don't really understand how i ended up here... one of the most famous women in the world. ..and losing sight of myself in the process. one of the most defining moments in contemporary british history — the death of princess diana, and the cataclysmic effect on the royal family. what do people want from me? for you to be mother to the nation. this series of the crown recreates events many will remember. do you know anything about it? the intense tabloid frenzy and diana's relationship with dodi al fayed are the focus of the first episodes. he said to me, every survivor has a date, the day they stepped on the landmine. and i said, mine was the 29th ofjuly, 1981, my wedding. i couldn't have done it without khalid, who plays dodi. i think the two of us just held each other through that.

you just have to keep in the front of your mind the responsibility you feel to tell the story. the crown is obviously a drama not a documentary. but historians say it's lacking accuracy. what happened in private, we have no accounts for because they were very private moments. so they have to take liberties in terms of how did charles broke the news to william and harry. we don't know what the queen was like in those moments. so they will take artistic license. this final series depicts the drama and emotion that consumed a country, a family, and left a legacy that's still felt today. head over to the website for the latest on the war in gaza.

stay with bbc news. hello there. it's a very mixed picture of weather across the uk on thursday and the rain and the winds will return along with the milder feeling air over the weekend. but on friday it's looking largely dry. a few showers out towards the west, plenty of sunshine around. temperatures now close to the seasonal average. so we're between weather systems on friday. these fronts clear into the north sea. this is the weekend's weather, a deep area of low pressure approach. and from the southwest, we'll be seeing that by the time we get to the end of the day. but most of the day, it's certainly looking dry. the early cloud will clear away into the north sea a few showers across north west england, the isle of man down through wales and possibly the south west of england. and here it will cloud over, also northern ireland as we head towards the end of the afternoon. but plenty of sunshine around, temperatures close to the seasonal average, generally eight to 13 degrees. but still that cold air lingers across northeastern areas of scotland. as we head through friday night

and into saturday morning, that wet, windy weather spreads in from the southwest, brisk southeasterly winds, spells of heavy rain, the temperatures rising unusually through the night. so this is how we're set to start off saturday morning, between 12 and 14 degrees celsius out towards the south of england. the rain gradually clears its way eastwards, so it will turn a lot drier across much of england and wales, eastern scotland as we head through the afternoon, some showers further west. temperatures certainly very mild rising to 15 or 16 degrees celsius in the south, ten to 13 degrees celsius further north. now, that deep area of low pressure is still spinning its way eastwards as we head through sunday. the focus of the rain on sunday will tend to be towards the north. so across northern england and much of north west scotland, also northern ireland seeing some hefty showers at times, a few showers out towards western wales.

further south across much of england and wales is dry. but here we'll see some very blustery winds, gusts of 40 to 50 miles an hour. temperatures perhaps just that little bit lower. now, as we head through sunday night, the area of low pressure starts to clear away, but it does leave a legacy of showers. still, the milder air hangs on for part of monday, but you can see we draw down more of a northerly wind. so the temperatures are set to turn cooler as we head through it into the start of next week. a drop in temperature turning more settled, too, as we head into the middle of the week for most of us.
