(CNN) -- Jordan is launching an investigation into a stampede after a soccer game that left dozens of people injured Friday night, a government spokesman said.
Deputy Prime Minister Ayman Safadi said the incident occurred after at game at Amman's King Abdallah Stadium.
At least 150 people were injured, and 11 were admitted into various hospitals for treatment, Safadi said. At least 25 of those injured were police and security officers. Three police cars, 8 civil defense cars and other private cars were damaged in the melee.
Safadi said that the incident began when some of the crowd in the upper seating level began throwing bottles at fans of the losing team, who are required by regulations to leave the stadium first to avoid interaction with fans of the other team. Police officers tried to intercede, but a crush of people pushed fans against a fence that eventually broke from the pressure.
