The Afghan Air Force (AAF) received another four M-530 fighter jets from the United States, the Ministry of Defense (MoD) said on Sunday.

MoD spokesman Javid Ahmad Ghafoor said the four fighter jets were delivered to the AAF on Saturday.

He said pilots for the aircraft had already been trained and other technical staff made available. The M-350 jets would be used in combat missions.

The Pentagon has said eight more fighter jets would be handed over to Afghan security forces until March 2019.

A new Pentagon report about Afghanistan says that the process of strengthening and modernising Afghan security forces would continue and so far 30 Black Hawk copters have been handed over to Afghanistan.

According to the Pentagon, the Afghan security forces would receive the first AC-280 jets in January 2019 and seven more AC-280 fighter jets until March 2019.
