Two suicide bombings followed by clashes in Iraq's Anbar province west of Baghdad have killed 23 security personnel.
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 jihadist group.
There was no immediate claim of responsibility for the attack, but suicide bombings are a tactic almost exclusively employed by Sunni extremists in Iraq, including IS jihadists.
IS spearheaded a major offensive in June that overran large areas north and west of Baghdad, including significant parts of Anbar.
Tribal fighters have played a key role in keeping the jihadists from gaining further ground in Anbar, and Iraqi forces are now providing training to tribesmen at Al-Asad.
In a meeting on Monday with Suhaib al-Rawi, the newly elected governor of embattled Anbar province, Prime Minister Haider al-Abadi called for a "tribal revolution" against IS, the premier's office said.
He emphasised "the importance of the tribes and the sons of the province taking part in liberating their areas from the terrorist organisations".
