NEW YORK, US - THREE more bodies were found beneath the rubble on Monday, raising to seven the number of people killed when a giant crane fell and crushed a residential building in Manhattan, a police spokesman said.

The crane flipped over on Saturday, flattening a four-story townhouse with a bar on the lower level and damaging three other buildings, injuring more than 10 people.

Six of those killed were believed to be construction workers, including the crane's operator. The seventh victim was a woman visiting New York from Florida, police said.

Authorities were investigating the cause of the collapse.
