An unmanned supply rocket bound for the International Space Station has exploded during its launch from the US state of Virginia.
Antares, a 14-storey rocket built by Orbital Sciences Corp, combusted seconds after leaving the seaside launch pad at Wallops Flight Facility.
The cause of the cargo ship malfunction has yet to be determined.
The initial planned launch of the spacecraft on Monday was delayed due to a sailboat in nearby waters.
The flight was expected to be the third contracted mission with the National Aeronautics and Space Administration.
The rocket was said to be carrying nearly 5,000 pounds (2,200 kgs) of supplies to six astronauts aboard the International Space Station.
