LEICESTER, England: British police searched for survivors on Monday in the rubble of a shop and apartment destroyed by an explosion that killed at least four people in the city of Leicester on Sunday evening. CCTV footage posted on the local newspaper’s website showed the entire front of the building shooting into the road as a car passed. The scene was then engulfed in fire. The Leicester Mercury said the shop was a Polish convenience store called Zabka Leicester and above it was a two-storey apartment. Police said there was no immediate indication that the explosion was linked to terrorism. Investigators were working to determine the cause and specialist rescue teams with search dogs were looking for survivors and further casualties. “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.” Local resident Harrish Patni told Sky News: ”We heard this massive explosion, the shop window six doors away vibrated and we thought it can’t be a car accident, it didn’t sound like a crash. “We came outside and there was a big cloud of smoke, bricks all across the road.” Leicester, in the center of England, has long been one of Britain’s most culturally diverse cities, with a large population of people from the Asian subcontinent and many other ethnicities.
