WATCH | ISIS militants blew up a historic mosque in Mosul, Iraq.
ISIS militants blew up a historic mosque in Mosul, Iraq, on Wednesday, that has been around for more than 800 years.
The Grand al-Nuri Mosque was a famous landmark, known for its 150-foot leaning structure, which gave the city its nickname "the hunchback."
ISIS's Amaq News Agency said that the mosque was destroyed in a U.S. airstrike, which the U.S.-led coalition denied, according to The Washington Post.
“This is a crime against the people of Mosul and all of Iraq,” Maj. Gen. Joseph Martin, commander of ground forces for the coalition, told the Post. “The responsibility of this devastation is laid firmly at the doorstep of ISIS.”
Over the past several months, Iraqi security forces have been closing in on ISIS militants in Mosul’s historic city center, around a square mile of territory on the banks of the Tigris, according to the Post.
"The battle for the liberation of Mosul is not yet complete, and we remain focused on supporting the Iraqi Security Forces with that objective in mind," Martin told Reuters.
