Syrian army defectors have launched attacks on president Bashar Assad's military targets near the capital Damascus.
The Free Syrian Army said that its main attack targeted a compound run by the Air Force Intelligence in the Damascus suburb of Harasta.
The renegade group says the other attacks targeted military checkpoints in the Damascus suburbs of Douma, Qaboun and Arabeen and Saqba.
The attacks come two days after defectors killed 34 soldiers and members of the security in the southern province of Daraa, on what was one of the bloodiest days of the eight-month uprising.
The UN says that more than 3,500 people have been killed since Assad launched a crackdown in mid-March.
