MacDonald House bombing

The MacDonald House bombing occurred on 10 March 1965, at the then Hong Kong and Shanghai Bank building (now known as MacDonald House) along Orchard Road of Singapore. The time bomb was planted by a duo of Indonesian saboteurs, during the period of Indonesia–Malaysia confrontation (also known as Konfrontasi). The explosion killed three people and injured at least 33 others.

During the Indonesian Konfrontasi where Indonesia openly opposed the formation of Malaysia, Indonesian saboteurs mounted a campaign of terror in Singapore. They were trained to attack military installations and public utilities. However, when the saboteurs failed in their attempts to attack these installations that were heavily guarded, they set off bombs indiscriminately to create panic and disrupt life on the island. By 1964, bomb explosions became frequent. To help the police and army defend Singapore from these bomb attacks, a volunteer force was set up. More than 10000 people signed up as volunteers. Community Centres served as bases for the volunteers to patrol their neighbourhoods. In schools, students underwent bomb drills. The government also warned Singaporeans not to handle any suspicious-looking parcels in the buildings or along streets.

Despite the efforts of the British, small groups of saboteurs managed to infiltrate the island and plant bombs. By March 1965, a total of 29 bombs had been set off in Singapore. The 10 March 1965 bombing of the MacDonald House was the most serious of the spate of bombings in Singapore, killing two bank employees; Suzie Choo (aged 36), private secretary to the Bank Manager, and Juliet Goh (aged 23), a filing clerk in the bank. At the time of the bombing, the building had also housed the Australian High Commission and the Japanese Consulate.

A bomb exploded at 3:07 p.m. in the Hong Kong and Shanghai Bank Building located at the MacDonald House along Orchard Road. Three people were killed and 33 others were injured.

The bomb, placed near a lift on the mezzanine floor of the 10-storey building, ripped off a lift door and an inner wall was blown inwards, leaving a mass of rubble on the ground floor. Every window within a 100 metres of the blast was shattered and cars parked near the building or driving past were damaged.

Within 4 days, the police arrested 2 Indonesian marines who were responsible for the MacDonald House bombing. They were charged with murder and sentenced to death.

Officers from Singapore's Special Branch and Singapore Police Force managed to track down and capture the two Indonesian commandos, Harun Said and Osman Hj Mohd Ali, who were members of the Indonesian Marine Corps. Subsequently, they were tried and convicted in a Singapore court, both were executed by hanging on 17 October 1968.

In 2014, Indonesia named a Nakhoda Ragam-class corvette warship (KRI Usman-Harun) after the two hanged commandos, worsening bilateral ties between Indonesia and Singapore. In response, Singapore banned the warship from its ports and naval bases.
