Two vintage MK-2 fragmentation grenades were dug up by construction workers conducting digging works inside the Manila City Hall compound on Monday afternoon, March 23.
The Mk-2 is a fragmentation hand grenade introduced in 1918 and widely known as the "pineapple" grenade due to its ribbed cast-iron body.
It served as the standard-issue anti-personnel grenade of US soldiers during WWII, the Korean War, and early Vietnam War and uses a timed fuse to deliver a lethal blast radius of roughly 10 meters.
According to the Manila Police District (MPD), the explosives were unearthed by the workers during a digging operation for the city hall's drainage system.
The men immediately informed the City Security Force personnel about the grenades, prompting them to seek assistance from the police.
The grenades were safely recovered by the MPD's Explosive Ordnance Disposal (EOD) team.
Authorities are still investigating the incident.
