Iraqi television reported that an Iraqi helicopter delivering aid to displaced Yazidis on Sinjar Mountain has crashed.
The state TV quoted an Iraqi military spokesman as saying on August 12 it was a Russian-made helicopter.
An Iraqi pilot was reportedly killed and a Yazidi lawmaker aboard the helicopter was injured in the crash.
Tens of thousands from the Yazidi religious minority have left their homes in northern Iraq after invading militants from the Islamic State (IS) gave them an ultimatum to convert to Islam, leave, or be killed.
Most of the displaced have been stranded on the Sinjar Mountain with little food and water to survive in the summer heat.
The Iraqi military, as well as the U.S., Britain, and France, have been airdropping food, water, and other aid supplies to the displaced.
