Seoul: One person was killed and five injured in an explosion Thursday at a South Korean weapons test site, the defence ministry said.
A spokesman said two of the five injured were seriously hurt by the blast, which happened when artillery shells were being tested.
Yonhap news agency, which earlier reported about 60 casualties, said later one person was killed and five injured when shells for 155mm self-propelled guns were being tested.
It said police and firefighters are investigating the cause.
The range at Pocheon, 40 kilometres (25 miles) northeast of Seoul, is operated by the state-run Agency for Defense Development.
"There was an explosion when our people were testing a fuse for shells," an agency spokeswoman said to a news agency, adding the institute is trying to determine the cause.
