A car bomb exploded Friday in front of a crowded East Beirut bakery only yards from the British consulate, killing 12 people and wounding at least 140, police said. The car, laden with 110 pounds of TNT and flammable liquid, was parked in a yard facing the bakery, which is located only 50 yards from the consulate in the commercial area of Jal El Dib. A police spokesman said 12 people were killed and at least 140 were wounded. Most of the casualties were people lined up in front of the bakery to stock up on bread in anticipation of a resumption of fighting. The blast, heard miles away, damaged the British consulate and shattered windows of shops and offices within a half-mile radius.
