The U.S. and Iranian ambassadors to Iraq will meet this week to discuss security issues in the war-torn country, a senior Bush administration official said Sunday. This will be the second meeting between U.S. Ambassador Ryan Crocker and his Iranian counterpart, Hassan Kazemi Qomi. Their May 28 meeting marked the first public and formal talks between U.S. and Iranian representatives since the United States cut off diplomatic relations 27 years ago. Iraqi Prime Minister Nuri al-Maliki, whose ruling party has close ties to Tehran, said this week's planned meeting would "strengthen the bridges of trust" between the two countries. "Ambassador Crocker expressed his satisfaction with the efforts made by the minister to hold this meeting," according to a statement from the foreign minister's office, the Associated Press reported.
