The suicide bombers attacked a mosque in the Al-Jubba area of Anbar where anti-jihadist fighters were resting, killing 10, after which clashes broke out that left a further 13 security personnel dead and 21 wounded.
Al-Jubba is located near the Al-Asad Air Base -- where American military personnel are deployed -- and the town of Baghdadi, an area that has seen heavy fighting between security forces and the Islamic State (IS) jihadist group.
