Baghdad: Iraq insists that the United States provide a "very clear timeline" to withdraw its troops from the country, Foreign Minister Hoshiyar Zebari said on Sunday.

The timeline is part of an agreement allowing US troops to stay on beyond the end of this year, Foreign Minister Hoshiyar Zebari said on Sunday.

Zebari said the agreement, including the timeline, was "very close" and would probably be presented to the Iraqi parliament in early September.
