Attackers have hurled crude bombs at several houses and businesses owned by Awami League (AL) leaders, including MP Kazi Nabil Ahmed, in Jashore, report agencies.
No casualties have been reported in the attacks that were launched at five locations early Sunday.
Leaders of Juba League and Bangladesh Chhatra League, affiliates of the ruling party, were also targeted.
A local AL leader of the town has accused the BNP and Jamaat-e-Islami of carrying out the attacks.
But another AL leader said a leader of his own party is responsible for the attacks, but refused to name the politician.
The bombs were thrown at Jashore-3 MP Kazi Nabil's house, district AL general secretary Shaheen Chaklader's hotel and the houses of two leaders from Juba League and Chhatra League between 1:00 am and 2:00 pm.
Police have collected bomb residues from the attack sites, said Jashore Additional Police Superintendent Ansar Uddin.
Zabeer International Hotel, owned by Chaklader, was targeted by assailants who were riding private cars and motorbikes around 1:00 am, according to Mahmud Hasan Bipu, office secretary for AL district unit.
The houses of Jubo League leader Touhidul Islam Chaklader Fontu, Chhatra League leader Rasel and transport leader Azizul Alam Mintu then came under attack.
"The BNP-Jamaat conspirators are trying to destabilise the country," said Bipu.
But Mohith Nath, president of AL upazila unit, disagreed. "Everyone knows that all the extortionists, arsonists and notorious murderers of this town are sheltered by one of our own leaders."
Four bombs were hurled at Kazi Nabil's home, of them four exploded. On Friday night, Jubo League leader Rajibul Alam's home was also targeted with bombs.
