Iraqi air force has destroyed three headquarters belonging to the Daesh Takfiri terrorist group in the militant - held city of Mosul, killing over a dozen terrorists, including an official. The Iraqi F-16 fighter jets carried out three airstrikes against the headquarters in the Tal Kayf district, located less than 13 kilometers (8 miles) northeast of Mosul, which led to their total destruction, Arabic-language al-Sumeria news website reported on Sunday. At least 17 Daesh terrorists were killed in the bombardments, including Ahmed Qasim al-Farahat, a Takfiri financial official. Iraqi armed forces have launched an offensive to recapture the country’s second-largest city, which has served as the main Daesh stronghold in Iraq since 2014. Gruesome violence has plagued the northern and western parts of Iraq ever since Daesh terrorists launched an offensive in June 2014, and took control of portions of the Iraqi territory. The militants have been committing heinous crimes against all ethnic and religious communities in Iraq, including Shias, Sunnis, Kurds, and Christians. Iraqi army soldiers and fighters from allied Popular Mobilization Units are seeking to win back militant-held regions in joint operations.
