A controlled on-site disposal of a 50kg World War II aerial bomb war relic at Jiak Kim Street is set to take place anytime between 8am and 6pm on Monday, Nov. 18, 2019.

The Singapore Police Force (SPF) said all residents living in the affected area have been made to leave their homes before 8am and return only after 6pm.

A copy of the police notice has been shared with Mothership by a resident:

Around 600 units of residents are affected.

Guests and staff of a hotel nearby have also been asked to leave.

Roads in the vicinity will be closed.

The police have set up a temporary holding area for affected residents at River Valley Primary School at 2 River Valley Green.

The disposal is carried out by the Singapore Armed Forces Explosive Ordnance Disposal team.

A 200m cordon has been set up around the area during the operation.

The bomb was found at a construction site in Jiak Kim Street on Nov. 12.

It is around the old Zouk club area.

"Loud sounds may be heard during the controlled on-site disposal of the war relic. The public is advised not to be alarmed," the police said.

Residents have been notified to leave their windows open or slightly ajar and securing items in their homes.

This is a precautionary measure.

An unlikely possibility highlighted was that windows might shatter due to pressure differences.

Pedestrians and residents are advised not to enter Kim Seng Road between the Singapore River and Havelock Road, Jiak Kim Street, and the footpaths along the Singapore River from Kim Seng Road to Saiboo Street.
