An air strike in west Iraq reportedly killed on Wednesday a senior figure in the Islamic State of Iraq and Syria (ISIS), Al Arabiya reported.
Senan Meteeb, the so-called ISIS "emir" of the western Anbar province, was reportedly killed by a coalition air raid in the Anbar city of Hit. Twenty-four other ISIS fighters were also reportedly killed.
The reported killing of Meteeb comes a day after Islamist militants shot dead 25 people from the Albunimr tribe in Anbar. The militant group has killed hundreds from the tribe.
The United States is planning to arm the Sunni tribesmen in Anbar to help bolster the battle against ISIS in the Sunni stronghold.
Tribal fighters in Anbar, whose cooperation with the Shiite-dominated state is seen as key to defeating ISIS, have been demanding more air support from Baghdad and the U.S.-led international coalition.
Shiite militias and Kurdish Peshmerga, backed by U.S.-led air strikes since August, have helped contain the radical Sunni insurgents and pushed them back in some provinces.
But the militant group has continued to make gains in Anbar.
