At least six people have died in an explosion near the entrance to the international airport of Yemen's southern port city of Aden.

An explosion near the entrance to the international airport of Yemen's southern port city of Aden on Saturday resulted in at least six deaths and around 20 injured, a senior security source and a medical source told Reuters, but it was not clear whether the incident was an attack.

An airport official said a small truck blew up at an outer gate to the airport, while a local official and two security sources said the vehicle was carrying petroleum products.
