Two military planes crashed during training flights in eastern and northern Saudi Arabia, the Defense Ministry said Monday.

The first plane went down Sunday in Saudi Arabia's territorial waters in the Persian Gulf and searchers are still looking for the pilot, the ministry said.

Officials did not provide any additional details, but the Al Madina newspaper reported the aircraft was an F-15C piloted by Fahad al Dusri.

The second plane was a Hawk jet trainer that crashed in the northern area of Tabuk when it experienced technical problems while landing.

The pilot ejected from the plane and survived the accident, the Defense Ministry said.

Investigators are trying to determine the causes of both accidents. EFE
