The National Directorate of Security (NDS) said a suicide bomber was appointed to carry out an attack on Gen. Dostum during a Buz Kashi competition in Jawzjan province.
A statement by NDS said the suicide bomber was looking to target Gen. Dostum by placing the explosives under the horse saddle.
This comes as the Afghan intelligence operatives foiled a plot to assassinate the first Vice-President two months after he took office.
At least four suspected militants including suicide bombers were arrested by the Afghan intelligence operatives during an operation in the 5th police district of Kabul city late in the month of November last year.
No group including the Taliban militants has so far claimed responsibility behind the assassination plots.
