Four armed men from the terrorist groups Japanese Red Army and Popular Front for the Liberation of Palestine attacked the Shell oil refinery complex on Pulau Bukom and later hijacked the ferryboat Laju and took its five crew members hostage.
[1][2] On 31 January 1974, a group of four men armed with submachine guns and explosives launched a terrorist attack on the Shell oil refinery complex located at Pulau Bukom, a small island lying to the south of mainland Singapore.
On 1 February 1974, a PFLP spokesman made a statement in Beirut that the attack was to serve as a warning to all monopolistic oil companies on one hand and imperialism in general on the other, especially the resulting perceived oppression of the Arabs in the Middle East.
This was followed by 7 days of intense negotiations between the Singapore government and the terrorists and during this same period of time, two of the hostages managed to escape their captors by jumping overboard in the middle of the night and were swiftly rescued.
This group of 13 consisted of four commandos from the Singapore Armed Forces (SAF) and eight other local government officials and was led by S. R. Nathan, the then-Director of the Security and Intelligence Division (SID) at the Ministry of Defence.
