CIA: Al Qaida will 'almost certainly' try to avenge Osama

WASHINGTON - CIA Director Leon Panetta on Monday said al Qaida would "almost certainly" try to avenge the US killing of Osama bin Laden.
"Though Bin Laden is dead, al-Qaida is not. The terrorists almost certainly will attempt to avenge him, and we must - and will - remain vigilant and resolute," Panetta said.
