At least 50 people, including a magistrate and two policemen, were injured in clashes between security forces and opposition activists who were protesting the police beating of a local MP during a previous demonstration.
The clashes erupted in northern Nilphamari district when activists from the main opposition Awami League tried to enforce a half-day general strike to protest police beating of local MP Asdauzzaman Noor, who has been hospitalised, during Tuesday's demonstrations in Dhaka, the private ATN Bangla channel said.
Police used batons to disperse stone throwing activists that left the magistrate, two policemen and 47 others injured, the report said, adding tension prevailed in the district.
Similar strike was also enforced in western Sirajganj district to protest the police action on former Home Minister Mohammad Nasim, a lawmaker from the Awami League, but there were no reports of violence.
Nasim has also been hospitalised with a broken arm and heart condition, ATN Bangla said.
More than 150 people were injured on Tuesday in fierce clashes between police and activists from the Awami League-led 14-party opposition alliance in their bid to lay a siege of the office of Prime Minister Khaleda Zia.
The opposition is demanding electoral reforms to ensure free and transparent vote, but Zia has rejected the demands by accusing her rivals of trying to foil the polls.
