Police in northeastern Bangladesh used batons and tear gas to disperse opposition activists amid a political dispute over who would oversee the next election, which is expected to be held in January, police and activists said Sunday.

Around 300 people were injured in the clash on Saturday evening, including some with bullets, the country’s leading Bengali-language daily newspaper Prothom Alo reported, adding that police had opened fire on supporters of the Bangladesh Nationalist Party, which is led by former Prime Minister Khaleda Zia.
