Turkey's military says a fighter jet has crashed during a training mission, killing its two pilots.

A military statement said the F-4E 2020 Phantom went down on Thursday in the province of Konya. The cause of the crash was not immediately known.

Turkey and Azerbaijan were holding joint military maneuvers in Konya at the time of the crash but it was not immediately clear whether the jet was taking part in the exercise.

The accident comes just a week after two military reconnaissance planes crashed in Malatya province, some 700 kilometers (435 miles) east of Konya, killing all four pilots.
