'Dangerous' WWII bomb found on Pacific island, defused

An "armed and dangerous" World War II bomb was dug up and defused Thursday on the small Pacific island of Nauru, the country's police force said.

Schools were closed and Nauru's 12,000 residents were urged to stay at home as Australian military specialists worked on the 500-pound (227-kilogram) explosive, which was first discovered almost two weeks ago.

Nauru's government declared a state of emergency across the island on Thursday morning, evacuating all houses within two kilometres (1.2 miles) of the bomb.

Police later said the device had been "disarmed and moved to a safe location for disposal".

A team of Australian bomb disposal experts were dispatched to Nauru to help, digging deep trenches and filling hulking containers with sand to absorb any explosion.

"The item is extremely dangerous so our key concern has been the safety of the people of Nauru as well as the vital infrastructure that supplies water and power that is in the immediate vicinity," Australian Lieutenant Jordan Bell said ahead of the operation.

The island microstate is one of the world's smallest countries and lies about 4,000 kilometres (2,500 miles) northeast of Sydney.

It was occupied by Japanese troops between 1942 and 1945.

The Pacific remains littered with unexploded ordnance decades after the end of World War II -- the legacy of brutal combat between Japan and the United States.
