April 22 (UPI) -- South Korea's foreign minister is coming under fire for downplaying a shooting incident at the Korean demilitarized zone during a press conference.

Chung Eui-yong said Wednesday at the Korea Press Center that North Korea acted with restraint at the heavily guarded border after delivering gunshots.

On May 3, multiple North Korean gunshots hit a South Korean guard post at the DMZ, prompting South Korea's military to fire back with 30 shots. Four bullet marks were found on the wall of the guard post, South Korea's joint chiefs of staff said at the time.

South Korea reported no injuries, but the incident raised tensions at the border.
