KABUL, AFGHANISTAN - An explosion Friday outside an entrance to Kabul University in the Afghan capital killed at least two people and injured 10, officials said.
Health ministry spokesman Wahid Mayar said two bodies and 10 injured people had been taken to hospital after the blast. No militant group has yet claimed responsibility.
A student at the university campus said the explosion happened when a number of students were waiting near the campus gate to attend an exam. One or two vehicles caught fire after the explosion.
The university compound houses several hostels where many students stay over the summer, attending classes and conducting research. The university is co-educational.
Traffic was light in the area because Friday is a weekly holiday in Afghanistan.
Kabul Police chief spokesman Ferdous Faramarz said a police team defused a second bomb that was placed close to the explosion site near a university gate.
