Thousands of people were forced to evacuate a bustling neighborhood of Hong Kong overnight while experts sweated through the delicate work of defusing an undetonated nearly 5-foot, 1,000-pound bomb left over from World War II. 

The U.S.-made bomb was found at a construction site in Quarry Bay on Hong Kong’s west side overnight Friday, and it isn’t the first bomb from the war to be found on the island. 

“We have confirmed this object to be a bomb dating back to World War II,” Andy Chan Tin-Chu, a police official, told reporters. He said that because of “the exceptionally high risks associated with its disposal,” approximately 1,900 households involving 6,000 individuals were “urged to evacuate swiftly.”

“Given the high risks involved in the handling of the bomb that officers from our #ExplosiveOrdnanceDisposal (#EOD) Bureau believe to still be in good condition—#HKPF devised the emergency evacuation plan upon the discovery of the bomb by workers in a construction site at No. 16-94 of fPan Hoi Street—for the sake of ensuring #PublicSafety,” the Hong Kong Police Force said in an alert on X. 

In 2018, experts defused another WWII bomb found at a construction site in Hong Kong’s business district. It also weighed 1,000 pounds and was the third bomb dug up since January of that year.

Hong Kong was occupied by Japanese forces during the war and was targeted by the U.S. in air raids there.
