On Saturday, an ambulance packed with explosives was detonated in a crowded area of Kabul City, killing 103 people, and injuring 235 including nine women.
The bombing came just days after a 15-hour siege by militants at the Intercontinental Hotel in the city that left 22 dead, including 14 foreigners.
The Taliban claimed responsibility for both attacks.
“I can show you the reports as we had prior to both attacks, how they [the militants] have come,” said Head of National Directorate of Security, Massoum Stanekzai. “But as you see, deferent tactics being used and for each and every tactic humans being used as tool [which] is the worst type of crime against humanity.”
The NDS Chief made the remarks at a joint press conference in Kabul, which was also attended by the Interior and defense ministers.
Interior Minister Wais Ahmad Barmak said that they have spotted the vulnerable areas in the capital and will tighten the security of areas around the city where the militants coming through.
“In upcoming weeks and months you will see changes in the security regime of Kabul,” Barmak said.
Meanwhile, in response to critics that call for resignation of the security officials, Defense Minister Tariq Shah Bahrami said that their resignation would not solve any security issue in the country.
“I don’t believe that the resignation could solve the problem, whenever the people have found better and qualified individuals than us, I will immediately resign and leave the post,” Bahrami insisted.
It comes after a number of political parties called on the security officials to step down, including Rahmatullah Nabil, a senior member of Mehwar-e Mardom-e Afghanistan party, who claimed that security officials are involved in political negotiations, instead of focusing on their main duties.
