In a statement on Thursday, Khatibzadeh also offered sympathy and condolences to the families of the victims of the attack.
“Unfortunately, the escalation of violence in Afghanistan has reached a very dangerous level, and if the international community, regional countries, and all the forces responsible in Afghanistan fail to pay attention to this issue, it is feared that violence would grow in the country and the security conditions would further deteriorate,” Khatibzadeh said.
Five Afghan security force members who were escorting the UN’s vehicles were killed in the attack on the Kabul-Jalalabad highway in Surobi District of Kabul on Thursday.
According to an Afghan interior ministry official, the insurgent Taliban were behind it.
Condemning the incident, the United Nations Assistance Mission in Afghanistan (UNAMA) said that no UN personnel were hurt or vehicle effected in an attack which hit a DPS vehicle that was escorting a UN convoy.
Attacks on international forces and foreign players have been rare since the Taliban signed a troop withdrawal deal with Washington almost a year ago.
However, violence against Afghans has escalated around the nation even as the Taliban and the Afghan government hold peace talks in Qatar.
