SINGAPORE — Experts from the Singapore Armed Forces (SAF) on Tuesday (Sept 26) conducted a controlled disposal of a World War II bomb that was uncovered last week in Upper Bukit Timah.

The 100kg World War II aerial bomb was first detonated at about 12.28pm, with flocks of birds flying from the noise and reverberation.

Plumes of white smoke could also be seen rising and members of the SAF Explosive Ordnance Disposal team were seen inspecting the site after the explosion.

A second detonation took place at about 1.45pm, more than an hour after the first. Dirt was seen flying from the ground of the explosion site due to the impact of the controlled blast.

Earlier in the day, residents living in the vicinity of the construction site were evacuated, with some of them seen leaving their housing blocks with their pets in tow.

CNA reported that more than 4,000 residents and stakeholders, and more than 1,000 units were to be affected by the bomb disposal.

During the operation, Bukit Panjang Flyover and Upper Bukit Timah Road will be closed to traffic from 11am to 7pm. This comprises the stretch between Woodlands Road and Petir Road for the flyover and between Petir Road and Cashew Road in Upper Bukit Timah.

The police said that they will provide an update on Facebook and X (formerly Twitter) when roads are reopened.

The authorities added that parking restrictions will be strictly enforced and vehicles found parked indiscriminately or causing obstruction may be towed.

Drone activities are also strictly prohibited in the bomb disposal operation area.

A temporary holding area has been set up at Senja-Cashew Community Club where residents may spend the day when the operations are ongoing.
