ZUMAR, Iraq — Kurdish peshmerga fighters have fought their way to Iraq’s Sinjar mountain and freed hundreds of Yazidis trapped there by ISIS fighters, a Kurdish leader said Thursday. “The peshmerga have managed to reach the mountain. A vast area has been liberated,” said Masrour Barzani, head of the Iraqi Kurdish region’s national security council, adding that 100 ISIS fighters had been killed. “Now a corridor is open and hopefully the rest of the [Sinjar] region will be freed.”
Backed by U.S. airstrikes, the assault ended the months-long ordeal of hundreds of people from Iraq’s Yazidi religious minority, who had been besieged on the mountain since ISIS stormed Sinjar and other Kurdish-controlled parts of northern Iraq in August.
