BAGHDAD 5 (Reuters) -- Islamic State's territory shrank by 40 percent from its maximum expansion in Iraq, and by 20 percent in Syria in 2015, as international forces pushed it out of several cities, the U.S.-led coalition fighting it said on Tuesday.
There was no immediate comment from the hardline Islamist group on the estimates from the coalition, made up of countries including Britain, France and Jordan that have been bombing its positions.

U.S. Air Force C-130 aircraft conducted an airdrop Oct. 27 in the vicinity of Al Asad Air Base, Iraq, to provide humanitarian aid for delivery by Iraqi Security Forces to members of the Iraqi Albu Nimr tribe. The aircraft delivered more than 7,000 halal meals which were retrieved by ISF and delivered to the tribe who recently relocated from their homes near Hit, Iraq, to flee ISIL aggression.
