The deadly explosion on Wednesday at the Al-Jihadi school in the city of Aybak, the center of Samangan province, which killed and injured a number of children and teenagers, has sparked widespread condemnation both locally and internationally.

According to an announcement by the Ministry of Interior, 10 children died and a number of others were injured in the explosion.

The United Nations Children's Fund (UNICEF) has also said in its response that it is horrified by the explosion.

UNICEF added that at least 288 children were killed or injured in Afghanistan in the first half of this year, including in attacks on schools and educational environments. According to the organization, it is believed that the real figure of Wednesday’s explosion is much higher.
