Six crude bombs have been exploded in front of Metropolitan Session's Judge's court in Dhaka.
A group of miscreants set the crude bombs off on the road in front of the court around 12pm.
Police fired six rounds of rubber bullets targeting the bombers. However, they managed to flee the scene.
Officer-in-Charge (prosecution) of the court Mofakkharul Islam said none was injured in the incident.
The ongoing countrywide blockade has been marked by explosions, arson and vandalism.
Hundreds of vehicles were burnt and attacked by miscreants during the non-stop blockade.
The BNP-led 20-party alliance has been enforcing a nationwide roads and waterways blockade since January 5, protesting BNP chief Khaleda Zia's confinement.
Blockade-related violence has killed at least 40 people over the last few weeks.
