Iraqi officials say their forces broke through Sunday to the jihadist-besieged northern town of Amerli, where thousands of people have been trapped for over two months with dwindling food, water and medical supplies.

The U.S. Defense Department says the United States conducted airstrikes Saturday against the Islamic State militants around Amerli and dropped humanitarian aid to those trapped in the town.  

Pentagon Press Secretary Rear Admiral John Kirby said  in a statement the U.S. Air Force delivered the aid alongside aircraft from Australia, France and Britain.

Kirby said the U.S. military conducted coordinated airstrikes against nearby Islamic State terrorists to support the humanitarian assistance operation.

伊拉克官员说，政府军星期天打进被伊斯兰圣战武装围困的北部城镇阿莫里。城里成千上万的居民已经被围困了两个多月，缺乏足够的食物、水或医药。

美国国防部说，美国星期六对阿莫里附近的伊斯兰国激进分子进行了空中打击，并向被困在阿莫里的民众空投了人道救援物品。

五角大楼新闻发言人科比海军准将发布声明说，美国空军与澳大利亚、法国和英国派出的飞机一道运送了救援品。

科比说，美国为保护运送人道救援的行动对附近的伊斯兰国恐怖分子实施了有计划的空中打击。
