Seoul -

Eleven people were injured on Monday evening when an electrical insulator exploded on a South Korean subway train just south of the capital Seoul, national news agency Yonhap said.

The explosion happened as the train was entering Geumjeong station at Gunpo, causing some of its windows to break and injuring 11 people on the platform, Yonhap reported.

“It appears that the accident occurred as an insulator connecting the train to the electric supply equipment suddenly exploded,” the agency quoted an official from train operator KORAIL as saying.

All passengers got off at Geumjeong and the train was taken out of service.

The accident happened less than three weeks after two subway trains collided in Seoul, lightly injuring 200 people.

The May 2 accident was blamed on a malfunctioning automatic stopping system. - Sapa-AFP
