Clashes between Sunni and Shiite students broke out at Kabul University today, leaving one student dead, according to local authorities cited by the Associated Press.
The violence comes as Shiites worldwide mark Ashoura, mourning the death of Imam Hussein bin Ali, Prophet Muhammad's cousin and son-in-law, whom Shiites believe is his rightful successor in a dispute that has divided the Islamic world. Today's events signal the start of a 10-day grieving period.
It was not immediately clear what started the fight between the students, which officials told AP involved several hundred people throwing stones and punching each other, leaving six injured and damaging university buildings. Classes have reportedly been canceled for the next 10 days.
Some Sunni Muslims consider Shiite events like Ashoura sacrilegious, but it was unclear whether or not such tensions played a role in the students' conflict.
General Mohammad Zahir told AP authorities are investigating the incident.
