The base is shared by the Afghan army and the National Directorate of Security (NDS), Afghanistan’s main intelligence agency.
“As a result of this attack, seven Afghan army soldiers died and three others were wounded. Meanwhile, in this attack, three NDS staff were also injured,” the ministry said in a statement.
The Taliban claimed responsibility for the attack.
The Reuters news agency, citing the district governor of Dawlat Abad, put the number of fatalities at 15.
The Taliban had a day earlier claimed responsibility for a fatal roadside bombing that targeted American and Afghan forces in northern Kunduz Province. One American soldier was killed in that attack.
