Saudi mosque bombing targets police, at least 13 dead

The Interior Ministry's statement said 10 of those killed were members of the security forces. 

The state-owned Al-Ekhbariya news channel earlier gave a higher death toll, reporting that 17 had been killed in the attack. It was not immediately clear why there was a discrepancy, but conflicting reports are common in the chaotic aftermath of bombings.
