At least 52 Islamic State militants were killed on Monday in separate clashes and US-led coalition air strikes in Iraq, security sources said. In Iraq’s western province of Anbar, hundreds of soldiers, police officers, Shia and Sunni militias launched an operation in the militant-seized town of al-Baghdadi, some 200 km northwest of the Iraqi capital Baghdad. They retook control of part of the town, including its main police headquarters, after heavy clashes with the IS militants, Xinhua cited a provincial security source as saying. The clashes left more than 20 militants killed, the source said without giving details about the casualties of the security members.
