A spokesman for the country's interior ministry said the explosion took place at the entrance of the military facility which is right next to Kabul international airport.
"This morning an explosion took place outside Kabul military airport, due to which a number of our citizens were martyred and injured," spokesman Abdul Nafi Takor told Reuters news agency.
Residents living close to the facility reported a loud explosion before 8 a.m. local time (3:30 a.m. UTC), and said the area had be closed off by security forces.
While the circumstances and cause of the blast have yet to be determined, there have been numerous attacks against the Taliban since the group took power in Afghanistan in August 2021.
The so-called Islamic State – Khorasan Province, a local affiliate of IS, has in the past claimed responsibility for many attacks.
