A World War II bomb found during construction work Tuesday near the Frankfurt Airport closed a heavily travelled section of autobahn and disrupted flights at Germany's busiest airport, dpa reported. The 500-kilogram British bomb is to be defused Tuesday evening and all landings are to be stopped until it is disarmed, said a spokesman for Deutsche Flugsicherung, the company responsible for air traffic control in Germany. Initially, one of the airport's four runways was closed for landings because bomb disposal experts said the site where the bomb was found could not be overflown, the spokesman said. Planes were allowed to take off from the runway, but only in the direction away from the bomb site. The bomb was found directly on the autobahn, which was closed, causing long traffic jams. It was outfitted with a chemical detonator, increasing the difficulty of the bomb disposal team's job. Unexploded bombs dating back to the aerial bombing of Germany during World War II are still frequently found. Most local authorities have teams working full-time to detect and defuse them. -- SPA 20:48 LOCAL TIME 17:48 GMT تغريد
