An attacker has set off a grenade among a group of university students in Afghanistan's capital, Kabul, killing himself and wounding five students.
On Sunday, the assailant, dressed in a school uniform, struck a neighborhood dominated by ethnic Hazaras, a Shia Muslim minority frequently targeted by extremist groups.
Nasir Nadery, the district police chief, said the attacker, who slipped past two guards, was wearing an explosives vest that failed to explode.
The attack was carried out as students were inside a private compound where they were taking classes to prepare for university exams.
No individual or group immediately claimed responsibility for the attack, which resembled previous assaults carried out by the Daesh Takfiri terrorists.
The Hazara community, the poorest of the country’s ethnic groups, accounts for about 22 percent of Afghanistan’s population.
