Rescuers at NY crane crash site

Rescuers in New York have been searching for survivors in the rubble of the apartment blocks crushed when a construction crane toppled into them.

At least four people were killed in the accident and 10 injured, Mayor Michael Bloomberg has said.

He told reporters that three of the injured were in a serious condition.

He said the collapsing crane - which had stood 19 storeys high - "basically just flattened" an apartment building on Manhattan's Upper East Side.

"It's a horrible situation, very gory. There's blood in the street," said Lieutenant Governor David Paterson, who is set to replace outgoing Governor Eliot Spitzer on Monday.
