Islamic State

The expected vote on whether to authorize the Obama administration's plan to arm and train moderate fighters comes as the president meets with military officials at U.S. Central Command.

The air attacks on Islamic State forces were requested by Iraqi security forces engaged in combat south of Baghdad.

Most Americans are far from clear as to what this "ISIL" monster is, other than a few shadowy, portentous figures on disturbing videotapes.

The chairman of the Joint Chiefs of Staff told a Senate panel he supports the president's plan to combat Islamic State militants but that if it proved necessary, he would recommend U.S. ground forces.

Representatives from more than 20 countries have gathered in the French capital to form a coalition to defeat the insurgency.

The secretary of state's visit to Baghdad comes ahead of President Obama's speech tonight to outline a plan to combat the militant group.

On a weekend that saw extremist group the Islamic State release a video showing the murder of a Western hostage, support for a coalition to fight the group is building.

This weekend, David Haines' family publicly asked his captors to contact them. Instead, the group released its third video showing a Western hostage being killed.
