A worker injured in a drydock collapse in Russia in October has died.

Radio Free Europe cited a Russian government spokesman as saying the man passed away in intensive care after being unconscious for nearly a week.

He suffered multiple injuries and hypothermia.

Four men were injured and one was reported missing following the incident at Rosneft's 82nd Repair Shipyard near Murmansk.

At least one crane fell when the dock sank, damaging an aircraft carrier.
