An unidentified terrorist threw a hand grenade at Kim Il-sung, then assistant commandant of Pyongyang and officer in the 88th Separate Rifle Brigade of the Red Army, during a crowded rally in downtown Pyongyang.
A Soviet officer, Yakov Novichenko, a native of the Novosibirsk region, noticed the terrorist's hand movement. He caught the grenade on the fly and covered it with his body. Novichenko lost a hand and an eye, but the future DPRK leader remained unharmed. Novichenko became the only Soviet citizen awarded the highest title of honour of North Korea – Hero of Labour.
After the liberation of Korea from Japanese occupation, the territory north of the 38th parallel was controlled by Soviet forces, and to the south – by US forces. Pyongyang was the largest city in the Soviet zone. Kim Il-sung was an active participant in the anti-Japanese guerrilla movement and a Korean officer in the 88th International Brigade manned by Korean, Chinese, and Central Asian soldiers.
In December 1946, Kim Il-sung would be appointed chairman of the North Korean organisation bureau of the Communist Party of Korea, and in February, he would head the Provisional People's Committee of North Korea. On 9 September 1948, the state of the Democratic People's Republic of Korea appeared on the world map, with Kim Il-sung becoming its prime minister. He would die in 1994; Yakov Novichenko would outlive the North Korean leader he had saved by five months.
