Thousands of families from the Yazidi minority community are trapped on the Sinjar mountain without food and water after fleeing the rampaging fighters of the Islamic State, also known as Islamic State of Iraq and Syria or ISIS.
So far, US military aircraft have delivered more than 52,000 meals and more than 10,600 gallons of fresh drinking water, providing much-needed aid to the displaced Yazidis, who urgently require emergency assistance.
