A gunman who took three hostages at the Discovery Communications headquarters near Washington DC in the USA has been shot dead by police and his captives have been set free.
It is understood the gunman was an environmental activist and was upset with the channel’s programmes.
He was wearing what appeared to be metallic cannister devices on his front and back. He also pulled out a handgun and was waving it around.
Officers had blocked off surrounding streets, evacuated the building and asked those nearby to stay inside. The hostage-taker had been carrying explosives.
The three hostages were released unharmed.
