Three explosions rocked a high school in western Kabul on Tuesday, killing several people, according to Afghan security and health officials.
Many residents in the neighbourhood belong to the Shia Hazara community, an ethnic and religious minority frequently targeted by Sunni militant groups, including Islamic State.
"Three blasts have taken place ... in a high school, there are some casualties to our Shia people," said Khalid Zadran, the spokesman for Kabul's commander.
