Four Iraqi Towns Fall to ISIS Militants, CNN Reports

Four towns in the western Iraqi province of Anbar have fallen to ISIS militants, CNN reported, citing a senior Iraqi security official.

In addition to their offensives in northern Iraq, CNN said, the militants were controlling Al-Qaim, Rawa, Ana, and Huseiba, said the senior official based in Anbar.

Most importantly, the Islamic State in Syria and Iraq, or ISIS, controlled the strategic town of Al-Qaim on the border with Syria, where the enemy fighters enjoy a stronghold, Iraqi security officials said Saturday.

Together, the four towns are situated along a highway from Syria to Baghdad, heightening possibilities that the militants could now march from the west to lay siege to the Iraqi capital. One of the four towns, Huseiba, is just 100 kilometers, or 62 miles, outside Baghdad.

Iraqi government officials didn't have an immediate comment, other than security officials saying they were expecting troop reinforcements in Anbar.

According to CNN, the senior official said that several Sunni tribes are aiding and supporting ISIS in Anbar.
