Four university students have died and about 10 were feared trapped after the roof of a building collapsed in a South Korean city during a welcoming ceremony for first year students, officials said.
Twenty other students were rescued and taken to hospitals, according to an official at the state-run National Emergency Management Agency.
About 1,000 students from Busan University of Foreign Studies were at an orientation event for first-year students in the south-eastern city of Gyeongju, the official said. About 450 were in a building when its roof collapsed.
He said many managed to get out by themselves and about 20 were later rescued and taken to hospitals. He did not provide further details.
