The Iraqi military received an additional four F-16 fighter jets over the weekend, US Presidential Envoy for the global coalition to counter the Islamic State Brett McGurk said on Monday.

"Iraq received four new F16s this weekend bringing total to ten, all playing integral role in fight against #ISIL," McGurk wrote in a tweet.

As part of its ongoing fight against the Islamic State, Iraq has ordered 36 F-16s from the United States, at a cost of more than $2 billion. The last delivery was made in February, when the United States delivered two F-16 jets.

The international US-led coalition against the Islamic State includes more than 60 nations and has been conducting airstrikes against the terrorist group in Iraq and Syria since August 2014.

The Islamic State, also known as Daesh in Arabic, is outlawed in Russia and numerous other countries.
