Four people have been killed when a crane collapsed on a busy street in the northwest US city of Seattle.
The crane fell into traffic, crushing six cars, the Seattle Fire Department tweeted on Saturday (local time).
"There are a total of 4 fatalities, and 3 injured patients that have been transferred to the hospital," the tweet said.
"A crane working on a South Lake Union project under construction fell Saturday at about 3:30 pm, pinning cars beneath it and killing four people," the Seattle Times newspaper reported.
The crane was being used in the construction of a new Google building, the Daily Mail reports.
Among the four dead were the two crane operators and two people in separate vehicles, the paper quoted Seattle Fire Chief Harold Scoggins as saying.
The paper quoted an eyewitness as saying there were heavy winds in the area at the time.
"It was terrifying," Esther Nelson, a biotech research assistant who was working in a building nearby, told the paper.
"I looked up. The wind was blowing really strong," she recalled. Nelson said she observed what happened from a break-room window.
She said she saw the crane - which was working on the top of the building under construction - snap in half and saw one half collapse onto the building and the other half plunge to the street.
