The blasts are the latest in a string of large-scale attacks targeting the Syrian regime's military and security installations. The opposition Syrian National Council says it's not capable of carrying out such attacks. The U.S. says al Qaeda in Iraq could be behind the attacks.
The first explosion around 7 a.m. struck the heavily fortified air force intelligence building, followed by another explosion at the criminal security department. Both explosions were several miles apart in Damascus, at approximately the same time, the Interior Ministry said. State-run news agency SANA said a third blast went off near a military bus at the Palestinian refugee camp Yarmouk in Damascus, killing the two suicide bombers.
The U.N. says well over 8,000 have died since the uprising began a year ago, inspired by Arab Spring revolts across the Middle East and North Africa.
