BBC: The United States House of Representatives has voted in favour of pulling most combat troops out of Iraq by April next year.
The new legislation calls for the Pentagon to begin withdrawing combat troops within four months.
The vote comes despite President George W Bush's threat to veto any timetable.
Both the House and the Senate must pass separate legislation and then reconcile their two versions for a measure to be passed to the president.
Correspondents say the House of Representatives, controlled by the Democrats, is hoping to pressure the Senate to approve a similar timeline.
It is the third time this year the House has voted in favour of legislation to end US military involvement in Iraq. US House votes for troop pullout (more)
