UNITED NATIONS, Aug. 15 (Xinhua) -- UN General Assembly President Miroslav Lajcak on Wednesday called the suicide attack targeting an education center in the Afghan capital of Kabul "unacceptable."

Through his spokesperson Brenden Varma, Lajcak said many of the victims were young people preparing for university entrance exams, noting pursuing an education should not be risk to one's life.

The General Assembly continues to stand against terrorism and with Afghanistan, he added.

Up to 48 students were killed and 67 others injured in a suicide bomb blast targeting a private education center in Dasht-e-Barchi locality of Afghan capital Kabul on Wednesday, the Afghan public health ministry said.

The UN mission in the country condemned the attack, saying in a statement that "no justification whatsoever for targeting civilians, at any time, under any circumstances."

No group has claimed responsibility yet. However, people pointed finger at the hardliner Islamic State group, saying the extremist outfit could be behind the deadly attack as it did in the past.
