On September 14, 2017 (July 24, 2017 in the lunar calendar), Iraq suffered a series of bloody attacks. On September 14, 2017, Iraq suffered its bloodiest attack since the recapture of Mosul in early July. According to the French newspaper "Opinion" reported on September 14, Iraq local time on September 14, a series of attacks occurred in Zikar province, causing casualties are still unknown, but at least 74 people are known to have died, including Iranians. The terrorist organization "Islamic State" (IS) claimed responsibility for the attack. According to the report, according to security sources, the attack first took place at a hotel at noon on the 14th, and several attackers opened fire on the hotel with automatic weapons. The attackers then boarded a car and detonated it at a control point of security forces not far away. The highway where the second attack took place is a frequent route for pilgrims and tourists in neighbouring Iran. Several suicide attackers were involved in the attack, which killed "dozens", according to a brief statement issued by IS propaganda. Health officials in Zikar province told AFP that 74 people were known to have been killed and 93 wounded in the attack. The report pointed out that the attack took place as IS was losing ground in Iraq. In early July, Iraq's second-largest city, Mosul, returned to Iraqi government control after three years in the hands of ISIS. In late August, ISIS lost another stronghold, and Iraqi government forces retook the strategic town of Tal Afar in the northwest. ISIS currently has only two remaining strongholds in Iraq, one is Hawija, located 300 kilometers north of Baghdad, and the other is three towns on the eastern border. An Iraqi military official said that there are about 1,500 ISIS "jihadists" remaining in these three towns. With the assistance of militarized groups, Iraqi government forces are preparing to launch an offensive against IS's last strongholds in the coming days and weeks.
