Pyongyang: North Korea conducted large-scale artillery firing drills to strengthen its combat readiness and pre-war posture, state media reported Tuesday. The exercises come at a time of heightened tension as the country prepares for the annual joint US-South Korea summertime Ulchi Freedom Shield (UFS) exercise set to take place from August 18-28.

According to Anadolu Agency, the drills were held on Monday under the General Staff's combat training plan. The main objectives were to assess the proficiency of tactical artillery units and share best practices across the army, as reported by the Korean Central News Agency.

The artillery firing drills involved mortar units of various calibers engaging in simulated strikes on designated enemy targets, reportedly achieving 100% accuracy. The exercises were overseen by high-ranking officials including Marshal Pak Jong Chon, vice chairman of the Central Military Commission, and Vice Marshal Ri Yong-gil, chief of the General Staff.

On the same day, North Korea issued a statement denouncing the large-scale joint military exercise between the US and South Korea. The country warned that it would exercise its "self-defense" right in the event of a provocation.

It's notable that about 20 of the originally 40 scheduled drills in this year's UFS exercise have been postponed to next month. This decision was influenced by a heat wave, flood damage, and Seoul's apparent bid to improve ties with North Korea.
