KARACHI – A blast reported at the main state-run university in Karachi on Tuesday was probably caused by a firecracker, police said.
"It was a low intensity blast and was caused most likely by a cracker," Karachi police chief Fayyaz Leghari told Reuters.
Leghari said three people were wounded in the incident, though a senior university official estimated at least six.
"The blast took place outside the main cafeteria of the university and at least six people were wounded," said Kaleem Raza Khan, registrar of the University of Karachi.
This is the first such incident at an educational institution in Karachi, though the campus often sees regular, violent clashes between rival student groups.
Leghari said Tuesday's incident may be related to these rivalries but added police were investigating.
Last year, two suicide bomb blasts at the International Islamic University in Islamabad killed six people, including the bombers, and wounded at least 20.
