Iran and the United States will meet in Baghdad on Monday to discuss a committee they agreed to set up last month to deal with security in Iraq, Teheran's ambassador to Baghdad said. The meeting would be the third time the two countries have met in recent months to discuss Iraq. The first round in May broke a 27-year diplomatic freeze following the 1979 Islamic Revolution and US Embassy takeover in Teheran. "The two sides will exchange views on Monday concerning the details of a trilateral security committee," state-run television quoted Ambassador Hasan Kazemi Qomi as saying Saturday. Qomi said Iraq would participate as well, and the group would focus on "the composition and agenda of the security committee."
