At least 10 people were injured in a triangular clash among workers of ruling Awami League and main opposition BNP and police in northern Bogra district.
The clash erupted between Awami League and BNP workers when the latter vandalised an office of the ruling party in Baluarhat Bazar area in the district, police said.
The clashing activists locked into a fight with police when they rushed to the spot and tried to disperse them, local media reported. Two policemen were injured during the clashes.
Blockade supporters exploded three handmade bombs on the Topkhana road in Dhaka. However, none was injured. They also targeted a pick-up van carrying police with a crude bomb in western Rajshahi city.
Yesterday, an activist of Jubo Dal - a front organisation of BNP - was killed in clashes on the first day the nationwide blockade.
The BNP-led 18-party opposition alliance is boycotting the polls and political violence during nationwide strikes and blockades enforced by the opposition since November have left over 120 people dead and crippled the economy.
Hasina, however, insists that the vote will go ahead as planned.
