North Korea's military fired over 60 artillery rounds near Yeonpyeong Island on Saturday, a day after both sides staged live-fire drills in the same area near their contested maritime border. The artillery fire poses a threat to the peace on the Korean Peninsula and escalates tensions. North Korea's shells landed in a buffer zone created under a 2018 tension-reducing deal, which fell apart in November after the North launched a spy satellite. This comes after North Korea fired more than 200 rounds of artillery shells near Yeonpyeong and Baengnyeong islands.
