Four people were killed in the Bangladeshi city of Chittagong on Friday after police fired at protesters during a demonstration against a visit by Indian Prime Minister Narendra Modi, police officials said. "We had to fire tear gas and rubber bullets to disperse them as they entered a police station and carried out extensive vandalism," Rafiqul Islam told Reuters, referring to protesters. Mr Modi arrived in the capital, Dhaka, for a two-day visit to celebrate the 50th anniversary of Bangladesh's independence. The protesters in Chittagong were from the Hefazat-e-Islam Bangladesh, an Islamist group opposed to the visit by Mr Modi, who critics said has been pushing a Hindu-first agenda in India. Mohammad Alauddin, another police official in Chittagong, said that eight people were taken to a hospital in the city with gunshot wounds. Four of them died of their injuries. Protests also flared in Dhaka, where dozens of people, including two journalists, were injured in clashes with police, witnesses said.
