Rescue workers retrieved one body early Sunday in the northern French town of Lille, following an hours-long search through the rubble of two collapsed buildings. Two small adjoining houses collapsed in a shopping street in the city centre at around 9:15 am local time (0815 GMT) on Saturday. At first the collapses did not appear to have caused any casualties. The homes were evacuated during the night as a precaution following a warning by a resident that one of the walls was “warped”, police said. Authorities soon realised a doctor was missing after calls to his phone went unanswered. He had been lent an apartment in the building for the weekend. A body was located shortly before 1:30 am on Sunday and fire service Lieutenant Colonel Stephane Beauventre, who is leading the rescue operations, said they believed the victim was the doctor. “The body went to the forensic institute. It will be clearly identified later,” Beauventre said. Officials visited neighbouring houses on Saturday to check for cracks or gas leaks after the collapse. A resident of one of the buildings first noticed something was amiss in the early hours of Saturday, when he returned home and saw that “the building had moved”.
