Police said people should immediately evacuate the area and call 110.
The alert was issued in light of the latest tragedy in the Solomon Islands where two more fatalities, and two injured, were recorded due to injuries suffered from the blast of WWII previously unexploded ordnance (UXO) (bombs).
Thousands of UXO are said to remain scattered in the Solomons and other Pacific islands from when US and other Allied troops fought Japanese forces during World War II.
