were to take that action. it would be a strategic mistake and there would be severe consequences. and — england's cricketers slump to a 9—wicket defeat in the first ashes test, in brisbane. hello and welcome if you're watching in the uk or around the world. dozens of people are feared dead in the us state of kentucky after a series of tornadoes wreaked havoc across a wide area. the tornadoes ripped through the us states arkansas, kentucky, and into part of illinois on friday night. in illinois it an amazon warehouse collapsed in the storm. a rescue operation is taking place to find survivors. the governor of the us state of kentucky says as many as a hundred people could die in the state as a result of a series of tornadoes sweeping across the region. the governor andy beshear described it as the worst in the state's history. so first, just trying to confirm this figure of more than 50 feared dead in kentucky, according to the governor. yes, i fear that there are more than 50 dead in kentucky. the confirmation on each individual is coming in, but we are going to lose over 50 people, a lot closer to somewhere between 70 and 100. it is devastating. the extreme weather has caused widespread damage in other states. at least one person was killed in a care home in arkansas. in illinois, rescue workers have been trying to establish whether anyone�*s still trapped in an amazon warehouse after its roof collapsed. mark lobel reports. debris and power lines down in st charles county. tornado warnings were issued here before it struck a nursing home. the wild weather hit the top of this amazon warehouse in edwardsville, illinois. local reporters say that there are people inside. the family member of someone trapped in the complex was speaking to them at the time. he was on the phone with me while it was happening. the tornado was hitting the back of the building, the trucks were coming in and i told him tojump out of the truck and duck and we watch the building go up, stop hitting the cars, i told him i was on my way, just, you know, stay under and we came and now we cannot find him. others are concerned about those on the premises, too. i talked to him about eight o'clock tonight, a little before, i texted him and he was returning to the warehouse to drop his van off. i have not heard from him since. ijust heard through the news. we live in edwardsville, we lost power. so, i decided to come down here to see what was going on and i had no idea the building looked that bad and i am worried sick. ijust want to know if he is ok. the national weather service forecast more than 70 million people across parts of the mississippi, ohio and tennessee valleys would be affected, with concern over the length and nocturnal nature of these tornadoes, that can prove more destructive than daytime ones. mark lobel, bbc news. let's look at some of the reaction on twitter. before that i am getting information that we have further details

then it went of there and attract up to linfield and did massive damage there. it continued to track north waste all the way to mayfield, doing major damage along the entire path and on the south—west side. it has been in mayfield for six hours at the scene at the factory area is extremely grim. they have been bringing people out of both alive and injured and there have been people who have died and it has been nonstop. ambulances coming in and out of the factory for about seven hours, nonstop. two more ambulances have just passed about seven hours, nonstop. two more ambulances havejust

factory, and the building, a factory, and the building took a direct hit from the tornado which was a major tornado. the entire building has collapsed with people in back building. the degree is so

60 mph for hundreds of miles, hitting numerous cities and some major cities, you are going to have bad things happen and that is what is happening. what spawned them? first of all, we had record warmth and heat across the southern plains in oklahoma and texas and in the mississippi and arkansas and alabama and tennessee and missouri. the temperatures were in the low to mid 80s. they are

and heat, there is a powerfuljet stream overhead and an upper wave came out of oklahoma and this developed and raised up towards chicago and that powerful storm and jet stream was overhead and

forward for a coronavirus boosterjab — after research showed it significantly reduced the chance of developing symptoms, from the omicron variant. the preliminary study — by the uk health security agency — also suggests that 2 doses of vaccine, are not enough to protect people from catching the variant. cases of omicron have risen sharply in recent days, and could top a million by the end of the month. our medical editor, fergus walsh, reports. it is remarkable just how fast the omicron variant is spreading through a highly immunised population. new evidence suggests two doses of vaccine offer little protection from infection, while a booster cuts your risk of getting a mild illness by three quarters. but vaccination should offer much higher protection against severe disease. what scientists urgently need to know is what proportion of those infected will need hospital treatment. there are early signs from south africa that omicron may mostly cause milder illness than delta, but even a small proportion of a huge omicron wave could result in sudden and sustained pressure on an already stretched nhs. the public are being urged to recognize the potential threat from omicron. our public health advice is to take proportionate action from where we are now. that includes face coverings vaccinating, primary vaccine. getting tested when you've got symptoms, regular lateral flows, making sure that you ventilate spaces. and finally to think about the number of contacts that you have every day, working from home if you can, and other measures that will reduce the transmission of this in the community. the government says covid measures will be kept under review. any decision on further restrictions on people's lives and livelihoods will need very careful consideration, given the threat from omicron remains unclear. one thing is certain. this is the last news people wanted to hear in the run up to christmas. joining me now is professor danny altmann who is from the faculty of medicine at imperial college. good morning to you. we heard michael gove describing the situation that the uk is facing is deeply concerning. that was regarding the omicron variant. what is it

to visit each resident will be limited to 3 — and staff testing will be increased. our reporter, simonjones, has more details. they're getting into the christmas spirit at this care home in norwich, but the shadow of omicron looms. the home, though, says it's determined not to close to visitors. i'd be very sad if that was to happen. our main goal is, is that our doors will remain open. and we've listened to the families. we've listened to our residents. and what they really missed was, it was that contact. and what we've done is that we're still allowing the visitors to come. we have robust procedures in place and it's been transformational. but things are changing — under new guidance from the department of health, care home residents in england will only be permitted to receive visits from three people, plus one essential care worker. staff will have to take three lateral flow tests a week, as well as a weekly pcr test. and there will be a £300 million fund to recruit and retain care workers. as well as the extra testing for staff vaccination teams will be deployed to homes to make sure all residents and workers get theirjabs. here at the department of health, they say updating the visiting guidance and boosting the booster program will help protect some of the most vulnerable members of our society from the virus this winter. it's about balancing risk with the latest clinical advice. the care workers are overworked. i can only _ the care workers are overworked. i can only give — the care workers are overworked. i can only give sympathy to those people — can

have to put up with it. the aim is to maintain contact at christmas, but the changes reflect the concern over omicron and the pressure the care system is already under. simon jones, bbc news. many relatives of people in care homes are worried about what may happen. julie worsfold's mum is in a care home. she's 91. her dad died in a care home earlier this year. shejoins me now from droitwich in
