Combat engineers and men from the Explosive Ordnance Disposal (EOD) team from the Singapore Armed Forces (SAF) sucessfully detonated a war-relic at a Seletar construction site around noon on Tuesday.

The SAF said in a Facebook post that the 100kg war-relic that was "armed and more than 60 years old".

Construction workers told The Straits Times that the relic, measuring about 1.2 m long and believed to be an unexploded artillery shell, was placed in a sack and buffered by sandbags before its detonation.

Several offices in the surrounding Seletar Aerospace Park were evacuated around 9am as operations to secure the relic were underway. Several relics have been found and detonated this year, with the most recent one discovered at a construction site in Jurong in August this year.
