The death toll of the United Nations mission in the attack on the Kaj Higher Education Center is much higher than the death toll announced by the Kabul police.
Since his return to power, the Taliban have pledged to protect minorities and crack down on security threats.
However, Amnesty International said Friday’s attack was “a shameful reminder of the lack of accommodation and the utter failure of the Taliban, as the de facto authorities, to protect the people of Afghanistan”.
In May last year, before the Taliban returned to power, at least 85 people – mostly girls – were killed and about 300 injured when three bombs exploded near their school in Dasht Barchi.
Again, no group has claimed responsibility, but a year ago ISIS claimed a suicide attack on an educational center in the same area that killed 24 people.
The Islamic State has emerged as a major security challenge for the Taliban, but officials claim that their forces have defeated the jihadists.
