A bomb exploded Monday at a wholesale produce market in southern Baghdad, killing four people and wounding 14, Iraqi police officials said. The blast occurred shortly before 8 a.m. at the Rasheed market in Baghdad's southern Dora neighborhood _ the same market that was the scene of a car bombing last month that killed 15 people and wounded nearly 50, Associated Press reported. An Iraq police official said the bomb was planted near the front gate of the market, and exploded as trucks carrying fruits and vegetables were waiting to enter with their goods.
