An Indonesian military helicopter crash shortly after takeoff from Poso kills 13 passengers. Their mission was to try to capture Indonesia's most wanted militant, Abu Wardah Santoso, leader of the Islamic State affiliate East Indonesia Mujahidin network.
Kurdish forces, backed by U.S. airstrikes, capture several villages in an offensive to retake the Iraqi town of Sinjar from Islamic State militants, who overran it more than a year ago. The operation aims to cordon off the town, take control of Islamic State supply routes, and establish a buffer zone to protect the town from artillery, according to the Kurdish national security council.
The Islamic State captures a range of cities inhabited primarily by Assyrian-Chaldean Christians in Northern Iraq, notably Bakhdida, Bartella, Qaraqosh, Tel Keppe, Karamlish and Tel Isqof; thousands flee, while many Yazidis are caught in the newly-captured city of Sinjar.
