At least four people have been killed and another four injured in an explosion and fire in central England on Sunday, authorities said.
Another four people are in hospital and attempts to ensure no one else is trapped in the building have restarted after concerns about the structural integrity of a neighbouring wall forced emergency workers to stop on Monday afternoon.
"We've now got specialist search and rescue teams supported by search dogs on scene", Matt Cane, from Leicestershire Fire and Rescue, told AFP at the site.
A fire service spokeswoman said the property was a two-floor building with a loft conversion that had suffered a "pancake collapse", according to the BBC.
Leicester Police said on Twitter this evening: "There has been a major incident on Hinckley Road, Leicester".
Terrorism has been ruled out "at this stage", Leicestershire Police said.
Leicester is 177 kilometers (110 miles) north of London. I could see two people lying in the road, obviously being treated. "The flames started more or less upstairs so I thought it must be something to do with upstairs, the flats". Literally the whole of the side of the building had been blown out.More news: Once again, a major death becomes 'The Walking Dead'

Gas network Cadent said it had assisted emergency services on Sunday night by "isolating the gas supply" to the building and adjoining properties on Hinckley Road.
"Forget about the money, the most important [thing] is life", he said.
Mr Kurd said he did not know what happened to the other member of staff.
Police have closed Carlisle Street and part of Hinckley Road and are asking people to avoid the area.
Salvage crews work at the scene of a convenience store and home that were destroyed by an explosion in Leicester, Britain, February 26, 2018.
Another witness, John Alexander, described the explosion as "low, like a release of air rather than a boom" that caused "shook through the house".
"It is a joint investigation between the fire service and the police and the priority is to make the area safe", he added.
