Yazidi

This town in northern Iraq was home to more than 88,000 civilians in 2013. Today, there are none left living here.

Kurdish fighters have uncovered two mass graves outside Sinjar, northern Iraq, that was ruled by the Islamic State for more than a year before the extremists were driven out last week.

Thousands of women and girls have been brutally raped, beaten, and sold as slaves by the Islamic State.

During a key battle in the rugged mountains of a northern province earlier this month, U.S.-backed Syrian rebels collapsed before an assault by al-Qaeda fighters. Some surrendered their weapons. Others outright defected to the militants.

Dozens of Iraq's Kurdish peshmerga fighters will fly to Turkey on Tuesday and from there cross into the Syrian border town of Kobani to help fellow Kurds fight Muslim militants, a spokesman for the Kurdish force said.
