Oman was leading 2-0, and 4-0 on total goals, when the violence broke out in the first half. Players ran for safety to the locker room. Myanmar soccer chief Zaw Zaw appealed for calm but was also forced to leave the field.
The unrest came after Oman was awarded a penalty kick that Ismail converted in the 39th minute to make it 2-0.
It wasn’t immediately clear if the game would be replayed or whether Oman would be declared the winner by forfeit. Oman will almost certainly reach the third round of group play. Myanmar is likely to face disciplinary action from FIFA.
