In this Tuesday, Jan. 21, 2014 photo, Gunmen hold their weapons in Fallujah, 40 miles (65 kilometers) west of Baghdad, Iraq. Islamic militants controlling a mainly Sunni area west of Baghdad are so well-armed that they could occupy the capital, a top Iraqi official warned Monday, a frank and bleak assessment of the challenge posed in routing the insurgents as a new wave of bombings killed at least 31 people. Since late December, members of Iraq’s al-Qaida branch – known as the Islamic State of Iraq and the Levant – have taken over parts of Ramadi, the capital of the largely Sunni western province of Anbar.
