Transport and business ground to a halt in Bangladesh's south-western city of Khulna on Saturday as journalists called a daylong strike to protest against the killing of a colleague in a bomb attack.
Most offices, schools, shops and factories in the city of three million people were closed and authorities deployed extra police to avert violence, witnesses said.
Manik Saha, a senior correspondent of Dhaka-based Bengali-language daily Sangbad, died when an unidentified assailant threw a bomb at him on Thursday.
He was known for his vigorous writing on crime and against gangs that stalk people in the region.
Police said they were investigating the murder but had not made any arrests.
Saha, who also worked for the Bengali service of broadcaster BBC, was the 12th journalist among the hundreds of people, including politicians, killed in the region over the last 10 years, police and reporters said.
