The strikes take place days after Turkish President Recep Tayyip Erdogan stated that Ankara aims to clear its borders from terrorists up until Iraq.
According to Anadolu news agency, Turkish jets hit eight targets in northern Iraq, destroying shelters, hideouts and arsenals, belonging to militants, who were allegedly preparing to attack border posts.
