At least three people were killed and scores injured on Thursday, said police, as clashes erupted in parts of Bangladesh on the fourth day of a nationwide strike called by an Islamist opposition.
Police said two men were beaten to death in Buzpur town in southeastern Chittagong district in violence between supporters of the ruling Awami League (AL) party and Bangladesh's largest Islamic party, Jamaat-e-Islami.
In another wave of clashes in the southern district of Khulna, a protester from Jamaat was shot dead after police opened fire at 500 of its supporters during the strike.
The violence is the latest to hit Bangladesh, stemming from a continuing war crimes tribunal at which almost the entire Jamaat leadership is in the dock for crimes committed during the 1971 war of independence against Pakistan.
The latest killings brought the overall death toll from clashes triggered by the trials to 100 since January 21 when the court handed down its first verdicts.
"Two men were beaten to death during the clashes. We could not determine immediately which group they belonged to," Buzpur police chief Angshothowai Marma told AFP.
The clashes between some 1,200 secular AL supporters and several thousands of Jamaat supporters were triggered by rumours that the former were going to attack local Islamic seminaries, Marma said, adding that around 12 people were injured.
Jamaat called Thursday's strike to demand the release of the head of its student wing, Islami Chhatra Shibir. Police in Khulna said they opened fire after coming under attack from protesters.
"Police opened fire after they came under attack from 500 Jamaat supporters," Khulna district police chief Ghulam Rouf Khan told AFP, adding that the protesters fired guns and hurled home-made bombs at police.
"A Jamaat man, hit with a bullet in the chest, died on the way to a hospital," another police officer, Kazi Abu Salek, told AFP.
Some 20 Jamaat supporters were hit with bullets and five police officers were injured in the clashes in Khulna, online newspaper bdnews24.com said.
The war crimes trials have plunged the impoverished country into one of its most turbulent chapters since independence. Analysts fear lasting damage to the fabric of the world's eighth-most populous country.
