Reports from Bangladesh say four students have been wounded in multiple explosions at Dhaka University.
Witnesses say the blasts occurred as members of the student wing of the country's main opposition Awami League party were holding a protest march at the campus.
The injured were taken to a nearby hospital, but the extent of their injuries was not known. Police are investigating, but so far no arrests have been made.
After the blasts, student supporters of both the ruling and opposition parties held separate protest marches, blaming each other for the attack.
Matiur Rahman Choudhury has more on the story.
