On October 9, 1983, President Chun Doo Hwan was on an official visit to Yangon, the capital of Myanmar. During the visit, he planned to lay a wreath at the Martyr’s Mausoleum, to commemorate Aung San, who founded the independent Myanmar and was assassinated in 1947. As some of the president’s staff began assembling at the mausoleum, one of three bombs concealed in the roof of the memorial exploded. The huge blast ripped through the crowd below, killing 21 people and wounding 46. Among the dead were the Korean foreign minister, Lee Bum Suk, the economic planning minister and deputy prime minister, Suh Suk Joo, and the minister for commerce and industry, Kim Dong Whie. The rest of those killed were presidential advisers, journalists, and security officials, most of them South Korean; however, four Burmese nationals were also among the dead. President Chun was saved because his car had been delayed in traffic and was only minutes from arriving at the memorial. The bomb was reportedly detonated early because the presidential bugle which signalled Chun's arrival mistakenly rang out a few minutes early.
Police identified three suspects as an army major and two captains. One was shot to death two days after the bombing; suspect Kang Min-chul and the other remaining suspect tried to commit suicide by hand-grenade that same day, but survived, although Kang lost an arm. Kang confessed his mission and links to North Korea, an action by which he was able to avoid a death sentence and instead received life imprisonment. His colleague was executed by hanging. North Korea denied any links to Kang, who was sent to the infamous prison at Insein, north of Yangon
