Nine people have been killed in a suicide bombing at a Damascus mosque popular with Syrian anti-government protesters.
State television showed the devastation caused by the blast at Zain al-Abideen mosque, where there was heavy security ahead of Friday prayers. Reports claim that some of the security personnel were amongst the 20 people wounded during the bombing.
The identity of who carried out the attack is unknown, but a witness recalls seeing a man approach the security officials before blowing himself up.
It is the second explosion of the day in the Syrian capital, after another device was detonated near a garage used by forces loyal to Syrian President Bashar al-Assad. The blast hit a black car, wounding the driver, but no one else.
Damascus usually manages to avoid the bulk of the violence, in a conflict that has not been dampened by a ceasefire agreement that is over two weeks old.
Another 15 UN monitors are expected to arrive in Damascus by Monday, bringing the total to 30, ahead of a group of 300 monitors.
