Four people were killed when an explosion destroyed a shop in a Leicester street, police have said.
Another four people are in hospital, one with serious injuries.
Six fire engines were sent to the Polish shop with two flats above it after members of the public reported a large blast in the area in Hinckley Road at around 7pm on Sunday.
During the night search and rescue teams found four bodies in the collapsed building.
They are continuing to carry out a rescue operation and believe more people may be trapped in the building, which was still on fire on Monday morning.
“There are four confirmed fatalities at this stage and a number of people still undergoing treatment in hospital,” Leicestershire Police Superintendent Shane O’Neill said.
“We believe there may be people who have not yet been accounted for and rescue efforts continue in order to locate any further casualties.
“Once the site is deemed to be safe a joint investigation with Leicestershire Fire and Rescue Service will begin looking into the circumstances surrounding the incident, which at this stage is not being linked to terrorism.”
