Awwal 03, 1432 H/Feb 06, 2011, SPA -- French police evacuated 6,500 people on Sunday from a Paris suburb in order to defuse a World War Two bomb recently found on a construction site. The unexploded, 500 kg (1,100 lb) British bomb was discovered on Jan. 27 during works on a site where a Renault car factory once stood in Paris' western Boulogne-Billancourt suburb, Reuters cited local police as saying. Authorities evacuated residents in the vicinity as a safety precaution even though the bomb was not considered dangerous. They were able to return to their homes shortly after mid-day. The factory was used to make vehicles for occupying German forces during World War Two, which made the plant a target for Allied bombers.
