Fresh from success in Iraq, a Sunni extremist group tried to tighten its hold Wednesday on territory in Syria and crush pockets of resistance on land straddling the border where it has declared the foundation of an Islamic state.
The al Qaeda breakaway group that has seized much of Syria and Iraq has formally declared the establishment of a new Islamic state, demanding allegiance from Muslims worldwide in a move that could further strain relations with other militant groups.
The Sunni militant group in Iraq is a force roughly 3,000 strong and includes some Americans, a senior intelligence official told CBS News on Tuesday.
The House Intelligence Committee chairman warns that the Islamic State of Iraq and Syria are looking to expand its territory across the Middle East, including Israel.
