North Korean army invades South Korea

June 25, 1950

At approximately 4 a.m. (Korean Standard Time) on a rainy Sunday morning Democratic People's Republic of Korea Army (DPRK - North Korea) artillery and mortars open fire on Republic of Korea (ROK - South Korea) Army positions south of the 38th Parallel, the line then serving as the border between the two countries. The opening barrage is followed shortly by tank/infantry attacks at all points along the Parallel. At 11 a.m. North Korea announced a formal declaration of war and what is now known as "The Korean War" officially began. In this announcement North Korea claimed ROK forces on the Ongjin Peninsula attacked North Korea in the Haeju area (west) and their declaration of war was in response to this attack. This claim was bogus.
