The South Korean Ministry of National Defense on Jan. 4 released a video rebutting Japan's claim that a South Korean destroyer used fire control radar on a Japanese Maritime Self Defense Force (MSDF) P-1 patrol plane over the Sea of Japan on Dec. 20 last year.
The 4 minute, 27 second-long footage has been posted to YouTube.
Tokyo has criticized the incident as dangerous, saying the use of the radar usually comes right before an attack. On Dec. 28, the Japanese Ministry of Defense released video footage it says shows the lock-on incident and that the MSDF P-1 crew was flying by the book. Seoul has denied the destroyer used the radar, and demanded an apology from Tokyo for having the plane fly low over the ship.
