U.S. Military Official Warns Of Dangerous Escalation In Iran-Backed Attacks In Iraq

Anti-government protesters hold an Iraqi flag in Tahrir Square in Baghdad on Thursday. As Iraqis continue to demonstrate against their government, U.S. officials say Iran is stepping up attacks.

A rocket attack Thursday at Baghdad’s airport appears to be the latest in a string of attacks over the past five weeks that U.S. officials say have escalated both in frequency and potential lethality.
