Cuba has admitted being behind a stash of weapons found on board a North Korean ship seized in the Panama Canal.

The Cuban foreign ministry said the ship was carrying obsolete arms from Cuba, for repair in North Korea.

The ship was seized by Panama last week after "undeclared military cargo" was found hidden in a shipment of sugar.
