South Korean stocks closed lower on Friday as investors sought safer assets amid the tension surrounding the Korean Peninsula, analysts said. The Korean won fell against the US dollar.

The benchmark Korea Composite Stock Price Index dropped 13.73 points, or 0.64 percent, to close at 2,134.88. Trade volume was slim at 343 million shares worth 3.31 trillion won ($2.9 billion), with losers outnumbering gainers 592 to 207.

Despite the eased concerns, the South Korean market has been dogged by speculation that Pyongyang may stage another nuke or missile test in the near future.

"The market fell at a steeper pace on the remark made by Pyongyang which hinted that a nuke test can take place at any time," said Lee Kyung-min, a researcher at Daishin Securities Co.

Foreign investors offloaded a net 75.8 billion won worth of local stocks, while institutions scooped up a net 44.8 billion won.

Individuals bought a net 21.8 billion won.
