In early June, 2014, the Islamic State terrorist group, known as ISIS, brought Mosul under complete military control after fierce fighting with Kurdish militia units, which were forced to retreat northward. Armed with T-55 tanks and 105mm artillery pieces, the terrorists had attacked the city from the south and from the east. Mosul is a historical city lying on the Tigris River, in northern Iraq. It is the second largest city of this violence-torn Arab country. It is economically important for its oil industry. The capture of Mosul by ISIS is one of the main reasons behind the US-led airstrikes against the Islamic insurgent strongholds.
