According to a security official in the province, the mosque was in the city of al-Baghdadi, 90 kilometers to the west of Ramadi, capital of al-Anbar.
He told al-Sumaria news on Friday that ISIL militants planted explosives in the Al-Faruq Mosque and then blew up the historical building.
Last month, Takfiri militants belonging to the ISIL terrorist group demolished a mosque in al-Shifa district in the Iraqi city of Mosul.
The so-called Islamic State of Iraq and the Levant (ISIL, also known as ISIS and IS), control swathes of land in Syria and Iraq.
The ISIL started its campaign of terror in Iraq in early June 2014. The heavily-armed militants took control of Mosul before sweeping through parts of the country’s Sunni Arab heartland.
The terror group has been carrying out horrific acts of violence including public decapitations and crucifixions against all communities such as Shias, Sunnis, Kurds and Christians.
