Much of the violence was in the southern coastal town of Mathabria, where clashes broke out yesterday when thousands of ruling party supporters attacked police and border guards taking ballot boxes to the government headquarters.
At least five persons were killed and several others injured in Mathbaria that saw the deadliest violence. Apart from this, two persons were killed in Cox's Bazar and one each in Jhalakathi, Netrakona and Sirajganj in polls-related violence, The Daily Star reported.
Three persons died on the spot while three others passed away on way to hospital in Barisal, media reports said.
Awami League activists had laid siege to a college centre where the counting was under way, said police official Abu Ashraf.
Most of the dead were ruling party supporters, the report said.
Yesterday, 712 Union Parishad went to the polls, held on the party lines for the first time. The Election Commission initially had planned to conduct elections to 730 Union Parishad but it had to postpone the polls in 18 places due to legal complications.
The opposition Bangladesh Nationalist Party (BNP) has said almost all the local council polls were marred by violence, rigging and fraud including ballot-stuffing by the ruling party supporters.
The elections will not change the political landscape of the country, but a sweeping victory would consolidate Prime Minister Sheikh Hasina's hold on power ahead of the general elections in 2019.
