8. 10 March 1965 – MacDonald House Bombing
During the peak of Konfrontasi (1962-1966) between Indonesia and Malaysia, Singapore became an victim of terrorism when Indonesia sent two commandos to plant a bomb at the MacDonald House (formerly known as Hong Kong and Shanghai Bank Building).
Then Indonesian president Sukarno was openly opposed to the merging of Malaya, Singapore, Sabah, Sarawak and Brunei, and ordered armed attacks in East Malaysia, incited revolts in Brunei and carried out sabotage activities in West Malaysia and Singapore.
There were dozens of bombing in Singapore, and the one at MacDonald House was the most serious of all as two bank employees were killed and 33 injured. The two Indonesian saboteurs were caught and hanged in 1968.
