The meeting to discuss a committee Iran and the US agreed to set up last month to deal with security issues would be the third between the two countries in recent months over Iraq. The first round in May broke a 27-year diplomatic freeze following the 1979 Islamic Revolution and takeover of the US Embassy in Tehran.

"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."

He did not specify the officials who would attend the meeting, but indicated the discussions would be held at the "expert" level. The prior two rounds of talks included Qomi and US Ambassador Ryan Crocker.
