Paris : The international coalition and local forces fighting the Islamic State (IS) terrorists could take back Mosul, the group's stronghold in Iraq before summer after making major advances in the city area, French President Francois Hollande said on Thursday.

"In Iraq, the coalition operation allowed to reconquest of a large part of the lost territory thanks to the help of Iraqi forces and Peshmergas," Xinhua quoted Hollande as saying.

"IS is retreating and the objective is to oust it from Mosul ... I think it's possible ... to liberate the city before summer," he added.

France was one of the first European countries to join the US-led coalition against IS. Its fighter jets have bombed the group in Iraq since 2014.-Agency
