According to a statement by the Office of the President, General Abdullah has been assigned for the post of acting minister of defense.
The statement further added that Stanikzai will also serve as Ministerial Adviser to President Ghani.
Abdullah Khan was previously serving as the Chief of Staff in Afghan National Army Chief of Staff office before he was assigned as acting minister of defense.
This comes as President Ghani promised to introduce the nominees for Minister of Defense and National Directorate of Security (NDS) Chief during a gathering in the Afghan parliament late last month.
Ghani made the promise during a gathering in the Afghan parliament while announcing the government’s stance regarding the peace efforts and fight against corruption.
The gathering was organized shortly after Kabul was hit by a deadly attack which left at least 64 dead and 347 others wounded.
Masoom Stanikzai was the last nominee for the Ministry of Defense who was rejected by the Afghan lawmakers following his introduction to the parliament house.
The National Directorate of Security, the key intelligence agency of the country got an acting chief following the resignation of Rahmatullah Nabil last year.
Meanwhile, the Afghan lawmakers unanimously approved General Taj Mohammad Jahid as the new Minister of Interior during a confidence voting process earlier this month.
