In the 29th minute of his country's first World Cup match in 28 years, Haaland slid in at the far post to connect with a low cross from left back David Moller Wolfe.

Veteran Iraq striker Aymen Hussein out-jumped three defenders to power in a header in the 39th minute to equalise. But Haaland struck again four minutes later for his 57th goal in 51 international matches when he chased an under-hit Zaid Tahseen back pass that goalkeeper Jalal Hassan, after hesitating, blasted into the striker's knee and the ball rebounded into the net.

Norway substitute Leo Ostigard scored with a header from a corner in the 76th minute and an own goal by Hussein made it 4-1 in the final seconds. The win put Norway top of Group I ahead of France, which beat Senegal 3-1 earlier in the day.
