A plane carrying four soldiers crashed on Monday as a result of a technical failure, according to the Sudanese Army.

“A civilian Antonov plane today crashed at Port Sudan Airport as a result of a technical failure, leading to the deaths of nine people, including four military personnel. One child survived the crash,” Sudanese army said in a statement on Monday.

The crash came 100 days after fighting in Sudan broke out on April 15 between the army and the Rapid Support Forces paramilitary group in the capital Khartoum and states in western Sudan.

Port Sudan in the Red Sea state, located on the eastern coast of the country, is one of the cities that have been under the control of the Sudanese army since the war began.

Port Sudan airport is the only one still working in the country, making the city a vital transit point for much-needed foreign aid.

The war has left at least 3,000 dead across Sudan, according to a conservative estimate.
