Baghdad, Iraq ? The FBI sent a team to Iraq to lead the investigation into the car bombing of the Jordanian Embassy as a group linked to Osama bin Laden’s al-Qaida terror network became a focus of the inquiry, U.S. officials said Friday. The death toll rose to 19 people with at least 50 others wounded.

L. Paul Bremer, the U.S. administrator of Iraq, announced the FBI would be heading the investigation, which already involves the U.S.-led coalition and the Iraqi police.

“We will do all we can to help the Iraqi authorities find these people and bring them to justice,” Bremer said in a press release distributed by the Defense Department.

In Saddam Hussein’s hometown of Tikrit, meanwhile, U.S. snipers killed two suspected arms dealers in a market.

The military also said a U.S. soldier was killed Thursday night in Baghdad while on duty. It was not clear, the Army said, if the soldier was attacked or shot accidentally.
