From CNN's Security Clearance blog:
The killing of three top officials by an explosion on Wednesday has left Syrian President Bashar al-Assad at a "decision point," a senior U.S. official told CNN.
"From an intelligence point of view the regime has to decide: fight or flight," the senior official said.
Another senior official from the Middle East region underscored that assessment, telling CNN the attacks indicate "strong cracks in the regime."
"This is a potential tipping point," the Middle East official said.
The nature of the violence and the proximity to al-Assad's inner circle of power is causing the increased concern from American government officials in the last few days, the American source said. A second senior U.S. official concurred with that assessment.
This morning on "Early Start," CNN's Barbara Starr on why a senior administration official says Al-Assad faces 'fight or flight' decision.
