Heavily armed militants flush with $450 million in stolen cash advanced towards Baghdad Friday, sending thousands fleeing from the Iraqi capital. Al-Qaeda-linked insurgents who seized large parts of the north earlier this week stole $450 million during a bank heist, Mosul Mayor Athier Nujaifi told NBC News, making the Islamic State of Iraq and al-Sham the richest terrorist group in the world. A senior cleric in Iraq issued a call to arms Friday, telling able-bodied citizens to help the government fight the Sunni militants.
