Substitute Mohanad Ali, who plays in the UAE for Dibba, and Amir Al-Ammari scored in Basra as Graham Arnold's men came from behind to secure a 3-2 aggregate victory after last week's 1-1 first-leg draw.

Iraq, whose only appearance at a World Cup was a group-stage exit in Mexico in 1986, progressed to the six-team play-offs where the last two tickets to the finals will be decided.

The UAE broke the deadlock in the 52nd minute, as Yahia Nader slipped the ball through for Brazilian-born forward Caio Lucas to fire the ball past Iraq goalkeeper Jalal Hachim.

But Iraq hit back midway through the second half when Mohanad Ali headed home Al-Ammari's free-kick.

The home side piled on the pressure late on, with Mohanad Ali missing two good chances to score a winner.

But VAR awarded Iraq the latest of penalties for a handball, and Al-Ammari stepped up to net the spot-kick and keep alive his nation's hopes of ending their 40-year wait to play in a World Cup.

Bolivia, New Caledonia and the Democratic Republic of Congo have also booked their places at the inter-confederation play-offs.

The other two play-off spots will be decided by the final round of CONCACAF qualifiers later Tuesday, with Jamaica and Panama currently in position to qualify for the mini-tournament.
