The father of the Jordanian doctor accused of killing CIA officers talks with CNN's Nic Robertson, while the suspect's brother tells CNN that his sibling's actions were "out of character" and that the man was "under pressure."
The man's father said he was called by an Afghan speaking in broken Arabic from Afghanistan. The Afghan told him his son was dead and that he died as a hero in an operation to kill CIA agents.
Al Qaeda has claimed responsibility for the suicide bombing in Afghanistan, according to a statement posted on Islamist Web sites.
Mustafa Abu Yazid, al Qaeda's commander of operations in Afghanistan and its No. 3 man, said the attack avenged the death of Baitullah Mehsud, leader of the Taliban in Pakistan who was killed in a missile strike last August, and al Qaeda operatives Saleh al-Somali and Abdullah al-Libi.
In the wake of the suicide bombing last week, new security guidance has gone out to U.S. bases across Afghanistan, U.S. military officials said.
