Dozens of North Korean soldiers briefly crossed the heavily fortified border Tuesday but retreated after warning shots were fired, Seoul said, the second such incident in two weeks as Pyongyang reinforces its frontiers with the South.
Landmine explosions near the border also injured multiple North Korean soldiers, the Joint Chiefs of Staff said, adding that Pyongyang had recently deployed troops in the area to clear scrub and lay mines, as relations between the two Koreas plummet.
