3 killed in phone masts collapse
Two contractors and a firefighter have been killed after two mobile phone masts collapsed in West Virginia.
The workers were tethered to a 300ft mast when the structure collapsed in Clarksburg. A member of the Nutter Fort Fire Department died after a second, smaller tower collapsed minutes later.
Two other contractors who were also tethered to the larger mast were hurt and taken to hospital with serious but not life-threatening injuries.
The contractors were doing maintenance to strengthen the mast's support when it collapsed, police said. The Occupational Safety and Health Administration is investigating.
