In Iraq, at least 100 people were killed and 200 wounded in one of the worst days of violence Iraq has seen in weeks. At least 70 died in a series of attacks in Baghdad. The violence comes as the new U.S. ambassador to Iraq, Ryan Crocker, was sworn in at a ceremony in the Green Zone.

U.S. Ambassador Ryan Crocker: “It was very important to me to have this ceremony here, not just in the interest of time, but because here in Iraq, America faces its most critical foreign policy challenge.”

Crocker’s predecessor Zalmay Khalilzad has been nominated U.S. ambassador to the U.N.
