A second terrorist leader has been arrested in Mosul. (Hat tip to Captain Ed.)

A statement identified the man as Abdul Aziz Sa'dun Ahmed Hamduni, also known as Abu Ahmed, and said he had assumed command of "terrorist operations" in the northern city of Mosul.

He had served as the deputy of the top Mosul militant leader identified as Abu Talha, the statement said.

"Abu Ahmed admitted to receiving money and weapons from Abu Talha as well as coordinating and conducting terrorist attacks in Mosul, the statement said. It said Hamduni was detained on December 22.

"The capture of Abu Ahmed, and the subsequent capture of Abu Marwan on 23 December, show significant progress in the inevitable destruction of the Abu Talha-led Al-Qaeda-Zarqawi terrorist network in Mosul," said U.S. Brig. Gen. Erwin Lessel, spokesman for Multi-National Forces-Iraq, in the statement.

Abu Marwan was also identified as a senior "terrorist" in the Talha organization.

So his arrest led to the arrest of Abu Marwan but was not announced until now. That means they were getting intelligence from him and using it to capture others. So they didn't want to announce his arrest until the information dried up.

Did he also give them false information that led to this bombing?

Late Saturday, a U.S. military statement said an F-16 jet dropped a 500-pound GPS-guided bomb on a house that was meant to be searched during an operation to capture "an anti-Iraqi force cell leader." "The house was not the intended target for the airstrike. The intended target was another location nearby," the military said in a statement.

The homeowner, Ali Yousef, told Associated Press Television News that the airstrike happened at about 2:30 a.m., and American troops immediately surrounded the area, blocking access for four hours. The brick house was reduced to a pile of rubble, according to an Associated Press photographer at the scene.

Or was it just a mistake by our military?

It seems odd, because we haven't read about very many bombing mistakes at all since the failed attempts to kill Sadaam during the early days of the war.
