Local time this Saturday, in San Salvador, the capital of Central American country El Salvador, a serious stampede occurred in the middle of a domestic football league match, killing at least 12 people. It is said that the disaster occurred after the stadium gate was closed, when a large number of fans still tried to force their way into the venue. Some officials said that they thought some fans had bought fake tickets and were investigating. According to the Ministry of Health of El Salvador, about 500 people have received treatment, and many of them have been transferred to hospitals.
