“In recent weeks, [U.S. Ambassador to Iraq James F.] Jeffrey and U.S. military officials have blamed three Shiite militia groups–the Promised Day Brigade, Ahl al-Haq and Kataib Hezbollah–for a wave of violence that resulted in the bloodiest month for U.S. forces here in two years. The groups have been trained and supplied by Iranian Revolutionary Guard special forces, and Iranian special agents have crossed into Iraq to provide some of the training and materials, officials said. Jeffrey provided details of the forensic testing after Gen. Lloyd Austin, commanding general of U.S. forces in Iraq, declined to do so earlier in the day. In a brief exchange, Austin said only that the weapons ‘are coming in from Iran, we’re certain of that.’ ”
