RIYADH, May 15 (Xinhua) -- A surveillance aircraft belonging to Saudi Arabia's wildlife authority crashed on Tuesday, killing four of the organization's staff on board, local news site Sabq reported.

The accident took place during the organization's routine surveillance in one of Saudi various reserves in north of the country.
