The South Korean military has resumed live-fire artillery drills near the western maritime border.

The South Korean Marine Corps announced that it conducted live-fire training involving K9 howitzers for the first time in seven years on Wednesday in Yeonpyeong and Baengnyeong islands in the Yellow Sea.

The Marines fired a total of nearly 300 rounds of its key weapons, including the K9, Chunmoo multiple launch rocket system, as well as Spike missiles and Bigung guided rockets.

The military had suspended live-fire exercises near the maritime border after the two Koreas signed the Comprehensive Military Agreement(CMA) in 2018, under which all military drills are prohibited near the border areas.

The military in January this year fired K9 howitzers in the western islands in response to North Korea's live-fire drills in the area but Wednesday's drill marks the first time such exercises officially resumed after the South suspended the inter-Korean military agreement earlier this month.

Seoul decided to suspend the inter-Korean military agreement in response to North Korea's trash balloons and ballistic missile activities.
