was also carrying what they said was a suspicious bag, so the area was cordoned off and a controlled explosion was carried out. no—one was hurt and neither the king nor queen consort was at the powless. scotland yard say this is not being treated as a terror related matter, rather what is being described as a mental health incident. the incident did not delay a huge military rehearsal in central london or the state occasion, up to weeks of separately, more than 7000 personnel from across the uk and commonwealth armed forces came together to rehearse for saturday's processions. soldiers, sailors, aviators and musicians from all three services are set to take part in two processions, accompanying their majesties to and from westminster abbey where the coronation ceremony takes place. they will be joined by personnel from 3a nations and six overseas

well so do take a look at bbc online. the warring military leaders in sudan have agreed a seven—day truce to start on thursday. the deal was announced by south sudan, which said the two sides had also agreed to name representatives for peace talks. this was the sudanese capital, khartoum, before the announcement was made. you can see smoke from the fighting across the skyline. on tuesday, the african union held an emergency meeting on the conflict,bringing together african, arab, un and other representatives. several failed truces have been attempted since violence began in mid—april. a 72—hour ceasefire extension announced on sunday was met with reports of more airstrikes and gunfire. 0ur diplomatic correspondent paul adams is following the situation from nairobi.

we know there have been invitations out of the warring generals to send representatives for talks stopping the un was suggesting even yesterday that sides had agreed to nominate representatives but we don't have a venue, a timetable or an agenda so at the moment there is no sign of any kind of meaningful israel's military has carried out further airstrikes on gaza in response to the firing of dozens of rockets from the palestinian territory into israel on tuesday. israeli officials said the strikes targetted weapons manufacturing sites and training camps of hamas, the islamist group that governs gaza. the latest flare up was sparked by the death of a prominent palestinian hunger striker in israeli custody. officials in texas say a man suspected of killing five

people in a neighbourhood dispute has been arrested after a four day manhunt. francisco 0ropesa is acccused of shooting five of his neighbours dead on friday when they complained about the noise he was making by firing his gun outside late at night. proof the us is deploying a further 1500 military personnel to its southern border at the request of the department of homeland security. the move comes ahead of an expected surge in migrants seeking to enter the united states, as covid restrictions lift next week. the deployment will last 3 months. top un leaders have defended press freedom and warned thatjournalism is facing a growing threat. the secretary general, antonio guterres, said press freedom was the foundation of democracy and the lifeblood of human rights. he said sixty—seven media

of loneliness. in a recent study, americans spentjust 20 minutes a day with friends. that's down from 60 minutes nearly two decades ago. less time with friends, more feeling of isolation. and young people are feeling the strain more than most. those aged between is—to—zii reported a 70% drop in time spent with friends during that same period. the us surgeon general has been speaking to the bbc about the effects of loneliness. when i went to medical school i didn't learn about loneliness and isolation. what i have learned against then it is a medical issue the rays of risking and physical illness like raising degree of stroke is profound, the increasing risk of premature death

associated with premature death on par with the rest we see from smoking daily and greater than the risk we see associated with obesity, so this is a profound public health challenge and why we need to address it with focus and resources and attention we for two public health issues like diabetes and obesity. live now to utah and let's speak to julianne holt—lunstad, a professor of psychology at brigham young university. she also worked with the surgeon general�*s team on this study. it's quite interesting what is new about the study, you measure loneliness against other things that can cause death, like cigarette smoking? this evidence has been emerging over the past couple of decades, across multiple scientific disciplines and this converging evidence gives us

considerable confidence in these effects, and of course .2 not only incredible personal effects but important risk to public health as well.

since then it seems like there has been nothing but tensions between the two sides so the eu was obviously quite desperate to trumpet any process or progress coming from these normalisation talks. and they have got something quite substantial on this joint declaration on missing persons. kosovo and serbia have to co—operate, they are going to form a joint commission chaired by the european union, they are going to pool their resources including satellite imagery, lidar and exchanging documents, official document in order to find the missing persons from the kosovo conflict in the late 19905 and identify them. the european union says there are still around 1600 people missing from that conflict and this of course has been a major issue between kosovo and serbia and also the families involved. the thing we don't have an

agreement on at all as the main bone of contention between kosovo and serbia and the ethnic serb minority in kosovo and that this association of majority serb municipalities. this is supposed to give ethnic serbs in kosovo a degree of autonomy and a draft for how it should look was presented at the meeting by kosovo serbs. it's been roundly rejected already by kosovo and the eu's foreign policy chiefjoseph paralysis they will need to be further meetings to try to come up with some sort of mutually agreeable plan for this association. around the world and across the uk. this is bbc news. this putting their skills to the test. it was all about accuracy for this weekend's hopefuls in the discipline called auto solo.- hopefuls in the discipline called auto solo. auto solo can be done on _

thousands of wrexham football fans have lined the streets of the city, to celebrate promotion—winning seasons by both the mens' and womens�* sides. the club's celebrity owners, rob mcelhenney and ryan reynoldsjoined an open bus tour. 0ur wales correspondent, hywel griffiths reports. cheering after a journey that took 15 years to complete, a promotion party they will remember for decades. 15,000 supporters lined wrexham's streets for a glimpse of the players and their celebrity owners, too. after so long in the football doldrums you have to savour success. it is the best day ever. 15 years of hurt. we have turned it around and we are going up, up, up. look what it means. the whole town is behind the boys. it is cracking, brilliant. wrexham! it is great for them to see the achievements of wrexham and they were mascots for the final home game of the season, as well, so for them to see the ending and the final victory parade,

it needed to be seen. this may be lower league football but ryan reynolds and rob mcelhenney series welcome to wrexham has propelled this club to another level. streaming globally, it brought new international fans. many find a way here to the turf wanting to meet one of the stars of the show, wayne, the landlord. it is bizarre. there are 40, 50 americans coming through the door every single day. like i say, maybe in five, ten years, i will look back and think, that was a bonkers couple of years. cheering. hollywood money may have helped to secure wrexham's success but don't discount the emotional investment of these supporters. just over a decade ago it was their cash which helped to save the club from insolvency and stopped it from being wiped off the football map completely. so, where next? the owners are ambitious and would like another party like this at the end of next season.

of course our goal is to get to the premier league. why wouldn't it be? if we can do that, whether it takes five years, whether it takes 20 years, that's the goal. that's the mission. and, not surprisingly, it's one these fans are fully signed up to. 0h, aye, straight through league two, no problem. you are confident? without a doubt, yeah. we will hammer them. play—offs at the very least. before that, the next stop on wrexham's journey is an american tour where they will face chelsea and manchester united. a mismatch on the pitch, but as a footballing brand, wrexham believe they can compete. hywel griffith, bbc news, wrexham. and from league two to the top flight, forbes has released its list of highest—paid athletes for 2023 and at the top of the list, bringing in $136 million is footballer christiano ronaldo, closely followed by his rival lionel messi who made a reported $130 million.

other big names in the top 10 — the footballer kylian mbape, the basketballer lebronjames and the only retired athlete in the top 10, just making the list in ninth is the tennis star roger federer. the top business stories are next. i will see you in a moment. hello there. on tuesday, it was a largely dry day across the uk. the best of the day's sunshine was across western areas, where we had some lovely blue skies through the afternoon in west wales, for example. elsewhere, though, there was quite a bit of cloud that bubbled up through the day. with high pressure in charge, actually where the winds came round, that high pressure, that was really important to how the day felt. in scarborough, with the onshore winds, temperatures just 11 celsius, quite cool. in contrast to that, the warmest place in the uk was here, managing 19 celsius, not far behind that for west wales, 18.6 celsius in a couple of spots. now at the moment, cloud is tending to melt away across england and wales, the thickest cloud over the next few hours across the north west of the uk, where you might find an odd spot of rain, but it's not really

going to amount to much, quite mild for western areas to start the day. quite chilly in the east with temperatures starting off wednesday morning down into low single figures. now, i think by and large for wednesday, there should be more in the way of sunshine to look forward to across england and wales. after a cloudy start in northern ireland, we should see some bright or sunny spells developing here. i wouldn't rule out a bit of rain, though, into the far north west of scotland, where it will continue to be quite cool. temperatures across england and wales for the most part, 15—18 celsius. so i think that will feel pleasant in the may sunshine. but then we start to see some changes coming up from the south west for thursday as a weather front approaches, and that is going to be spreading some rain. could be quite heavy as well for a time across southwest england before later in the day, the rain edges into parts of wales and the west midlands, probably. there will be some drier and brighter weather ahead of that, and temperatures could still reach around 18 celsius, but it will continue to feel quite cool across eastern scotland and northeast england with the winds coming in off the chilly north sea. now for friday, there's a general downward spiral into more unsettled

weather conditions with heavy showers or even some longer spells of rain. the air, though, is relatively mild with the winds coming up from a south westerly direction, 18 celsius, even if we don't get a great deal in the way of sunshine. but then on into the weekend, which, of course, is the coronation weekend, low pressure works up from the south west, and it does look like it will be turning increasingly unsettled. so i think rain will move into southern areas of england from the south west on saturday. so it could be quite damp for a time for the coronation. and then beyond that, we've got some heavy and thundery showers in the forecast for sunday.
