South Korea has made plans to hold a military drill on the Yenpyeong border island on the anniversary of the shelling of the island by North Korea in 2010.
The military maneuver, which will be launched on Friday, includes field and simulated exercises by marines and other naval forces, but it will not feature any live-fire exercises in order not to provoke Pyongyang.
"The exercise will be held... based on various scenarios of provocations and attacks by the enemy," a Marine Corps spokesman said on Monday.
During its most serious military reaction to Seoul’s military drill on November 23, 2010, Pyongyang hit the populated small island by dozens of artillery shells, which led to the killing of two marines and two civilians.
Seoul demanded an apology from the North over the deadly shelling, but Pyongyang said the shelling had been in response to the South’s live-fire exercise, which sent some shells on its side of the disputed Yellow Sea border.
Since the shelling, South Korea has deployed more troops on frontline islands as a preemptive measure.
South and North Koreas have remained technically at war since their 1950-53 conflict ended in an armistice, without a subsequent peace treaty.
