MANILA-Five people, including teenagers, died from unknown causes during a pop concert in a suburb of the Philippine capital, police said Sunday. The five were among an estimated 14,000 attending the “Closeup Forever Summer” open-air concert, headlined by Belgian DJ duo Dimitri Vegas and Like Mike late Saturday, investigating officer Giovanni Arcinue told AFP. Among the fatalities was a 33-year-old foreign man, believed to be American, said Arcinue.

“They just collapsed individually. They did not know each other. They were all in different places at the time,” he said.
