How Islamic State Grew Out of U.S Invasion of Iraq, Destruction of Nation

Militants from Islamic State stormed an air base in northeast Syria on Sunday, capturing it from government forces. Fighters from Islamic State have seized three Syrian military bases in the area in recent weeks. This comes as the Pentagon considers expanding its airstrikes against Islamic State in Iraq to include targets inside Syria. Meanwhile another journalist who had been kidnapped in Syria, Peter Theo Curtis, has been freed after two years in captivity by the Nusra Front -- another militant group in Syria. Calls have been growing for the United States to attack Syria since Islamic State posted video showing the kidnapped American journalist James Foley being beheaded. Foley was captured in Syria in 2012. Meanwhile in Iraq, officials say suicide bomber targeted a Shiite mosque in Baghdad today, killing at least 12 people.
