At least four persons were killed in clashes in Bangladesh today, taking the death toll to 25 in violence linked to the execution of a senior Jamaat-e-Islami leader, even as Prime Minister Sheikh Hasina warned of strong action against rioters.

Jamaat workers stabbed to death an Awami League supporter today, hours after three Islamists were killed in a clash with police in northern Lalmonirhat district.

Ten people belonging to minority Hindu community were injured when Jamaat activists attacked and set afire their houses at Kafirbazar area in the district, reports said.

At least 25 people have been killed in clashes since Thursday night, when Jamaat leader Abdul Quader Mollah, known as the “Butcher of Mirpur” for atrocities committed during Bangladesh’s 1971 liberation war, was hanged.

Mollah, who was hanged after the Supreme Court rejected his review petition, became the first politician to be put to death for war crimes.

Violence erupted at several places soon after his execution, which the Jamaat described as a “political murder” even as it vowed to take revenge.

Addressing a rally marking the 42nd anniversary of the Martyred Intellectuals Day yesterday, Hasina accused her arch-rival and main opposition BNP chief Khaleda Zia of backing Jamaat to protect the perpetrators of crimes against humanity.

“We have shown enough patience. We will not tolerate anymore. People of the country know how to reply these atrocities, we (government) also know how to respond to, control you,” she said.

Her comments came as Jamaaat called a nationwide strike today to protest the hanging of Mollah.

The strike started with clashes with law-enforcers, arson, vandalism and crude bomb blasts by Jamaat activists.

A patrol train derailed in northern Rangpur district today as Jamaat cadres removed rail tracks during the strike.

The government deployed additional police in the capital to check the violence during the strike.
