A person, who received severe burns in Friday's petrol bomb attack on a bus in Gaibandha, has succumbed to his injuries on Sunday.
The victim, Abul Kalam, 40, died at the burn unit of Rangpur Medical College Hospital around 3pm.
Dr Maruful Islam, head of the burn unit, confirmed the death of the person.
The death toll from the petrol bomb attack has now risen to eight.
Miscreants hurled petrol bomb at a bus in the district around 11pm while it was under police escort, leaving five people, including three children, dead on the spot.
Some 22 injured people were rushed to hospital, where two more victims succumbed to their injuries on Saturday.
Now 18 people are undergoing treatment at Rangpur Hospital, said Dr Maruful.
The police filed a case in this connection, accusing some 100 leaders and activists of the BNP-led 20-party alliance. Of the accused, 10 people have been arrested so far, said Sadar police station OC Rajiur Rahman.
The incident took place an hour after the Awami League Central Working Committee meeting ended, which decided to get tough against the BNP-Jamaat alliance’s ongoing blockade programme.
The Napu Paribahan bus had left Gaibandha Bus Terminal in a motorcade under police escort when it was firebombed in front of the Rural Electrification Board office in the Tulshighat area of Gaibandha Sadar.
Thirty passengers sustained burn injuries in the arson.
So far, more than 60 people have died and scores have been injured in different parts of the country in violence during the BNP-led alliance enforced non-stop blockade.
Of those, a large number of arson attacks are being conducted on highways. Hundreds of vehicles, including those belonging to law-enforcers, were burnt and attacked.
For most of the day, the BNP-led 20-party alliance enforced blockade and hartal had little impact on the lives of the people on its 34th day, aside from a few stray incidents of violence across the country.
Law enforcers continued a crackdown on alleged anarchists in different parts of the country.
In the capital, city dwellers experienced traffic jams on the roads, a sign of relative normalcy.
Crowds of people were seen on the streets attending to their daily tasks.
The BNP led 20-party alliance has been enforcing a non-stop nationwide blockade since January 5 in protest against the “confinement” of the party chief Khaleda Zia.
Khaleda Zia had been kept confined to her Gulshan party office since January 3 ahead of a party rally, marking “Democracy Killing Day.”
On January 12, the security was relaxed.
But Khaleda never came out; instead she said in a press conference that she was going to stay there and the blockade would continue unless the government took the first steps towards solution.
