There has been an attack on the Iraqi Central Bank in Baghdad in which at least 15 people have been killed and more than fifty injured. It is still not clear whether it was a bank raid or an insurgent attack or both. The Baghdad Operations Command said the attack began with a big explosion which set fire to a generator and its fuel tank. That sent up a big column of smoke and fire broke out in one of the bank's buildings. According to the official account, a group of three gunmen in military uniform tried to storm the main entrance. They were fired upon and blew themselves up. Another group of two men then attacked the back of the bank buildings, clashed with guards and also blew themselves.
