Fresh incidents of violence were reported in Bangladesh, following earlier arson attacks.
In Gopalganj, activists of the banned Chhatra League clashed with police during protests and road blockades linked to a student strike.
Protesters set fire to a police vehicle, vandalised several shops and a BNP office, and blocked roads in Tungipara, Kashiani and Gopalganj town. At least 10 people, including police personnel, were injured.
Meanwhile, two crude bombs exploded on the Dhaka University campus, seriously injuring a private car driver.
The latest incidents come amid a series of arson attacks including the burning of a parked bus in Faridpur that killed its driver, raising fresh concerns over law and order.
