Militants Take Key Cities In Iraq, Advance Toward Baghdad

Al-Qaida-inspired militants have captured two key cities in Iraq in the last two days, and they're now threatening to take Baghdad.

The Sunni extremists from a group known as ISIS, the Islamic State of Iraq and Syria, took control of Mosul, Iraq's second-largest city, on Tuesday, and on Wednesday took Saddam Hussein's hometown of Tikrit.
