North Korea has deployed three self-propelled howitzers near the border with South Korea, writes Reuters. A Reuters reporter saw three North Korean armored vehicles with artillery barrels pointing south. The South Korean news agency Yonhap identified them as 122 mm self-propelled howitzers. The journalist also noticed about 20-30 North Korean soldiers erecting a fence in the demilitarized zone. On September 21, a mine exploded in the demilitarized zone between North and South Korea, as a result of which three South Korean soldiers were injured. Seoul blamed it on North Korea, Pyongyang denies involvement. Photo: Kim Hong-ji / Reuters.
