Iran deployed its Revolutionary Guard to help Iraq battle insurgents from a group inspired by Al-Qaeda, according to a recent report. In the meantime, the US is mulling airstrikes to support the Iraqi government.

On Wednesday, Al-Qaeda affiliate insurgents from the armed group Islamic State in Iraq and the Levant (ISIL or ISIS) conquered former dictator Saddam Hussein's hometown of Tikrit, marking the second major loss for the Iraqi government of Prime Minister Nouri al-Maliki. Earlier this week, insurgents captured Mosul, the second-largest city in the country. With jihadists threatening Baghdad and security forces unable resist the Sunni Islamists' assault, Maliki turned to foreign powers for help, getting responses from two unlikely allies, Iran and the US.

Two battalions of the Quds Forces, which is the overseas branch of the Iranian Revolutionary Guard, moved to Iraq on Wednesday, the Wall Street Journal reported. There they worked jointly with Iraqi troops to retake control of 85 percent of Tikrit, security forces from both countries told the Journal. Iranian forces are also helping guard the Iraqi capital of Bagdhad, as well as two Shiite holy cities that the Sunni jihadists are threatening.
