A suicide bomb attack on a mosque being used by security forces in Abha, close to the Yemeni border in Saudi Arabia has left 13 people dead.
A senior Saudi official said today that the many of those killed were members of the security forces. The mosque was used by a Swat team tasked with domestic security, officials said.
It is not yet clear who carried out the attack and no group has yet claimed it.
Two deadly attacks on Shia mosques in May were claimed by the Islamic State (IS) group.
Saudi Arabia is also heading a campaign against Shia-led rebels in neighbouring Yemen. [myad]
