PATRAS, Greece — In its first Olympic competition since its country was shattered by war, Iraq upset Portugal 4-2 in a gritty, come-from-behind victory as about 200 chanting fans cheered and jumped wildly. Portugal went ahead in the 12th minute when Iraqi defender Habar Haidar accidentally kicked the ball into his own net as he tried to clear a pass by Cristiano Ronaldo. Three minutes later, however, Mohammed Emad tied it after picking up a rebound from the goalkeeper, Moreira.

Iraq went ahead 2-1 in the 28th minute when Mohammed Hawar scored on a soft shot after dribbling past the goalkeeper, but Portugal tied it with a minute to go in the first half on a goal by Bosingwa.

With the game tied at 2-2, Mahmoud Younis put Iraq ahead 3-2 in the 50th minute, and Sadit Salih scored during injury time to seal the victory.

Iraq leads Group D with three points, while Costa Rica and Morocco have one after playing to a scoreless tie.
