Tribal leaders of Iraq's Marsh Arabs have visited London to highlight their people's plight since they were driven from their villages by Saddam Hussein.

About 250,000 Marsh Arabs live in refugee camps and Iraqi cities.

They are unable to return to their homes since the marshes on which they depend were drained by the Hussein regime as a means of repression.

Their leaders asked Britain for help in re-flooding all the marshes, as the region is administered by the British.

Impromptu destruction of Saddam's dams by the tribes during the war has allowed the re-flooding of 50% of the old marshes and the return of about 30,000 people.
