Authorities in Korea say two small explosions took place Thursday at transit terminals in the capital. There were no injuries.
Police say the first explosion occurred at 11:22 a.m. in a locker at the city's largest rail terminal, Seoul Station. The device had wires and was fueled by a butane gas canister. Investigators say closed circuit television images recorded a man placing a backpack in the locker earlier in the day.
The second explosion occurred 33 minutes later at the Gangnam Express Terminal, eight kilometers away. Police say that blast was caused by a device similar to the one found at Seoul Station.
Investigators are uncertain of the motive for the attacks. No suspects have been named and there has been no immediate claim of responsibility by any group.
