One journalist was killed and three others were detained in Bangladesh in a year till December 1, said Reporters Without Borders (RSF).

According to RSF's annual round-up of violence and abuses against journalists, the number of imprisoned journalists worldwide reached a 30-year high this year.

A record number of 533 journalists were detained, 57 were killed, 65 were held hostage and 49 went missing across the globe, according to the reports published yesterday.

Bangladeshi journalists are exposed to police violence, attacks by political activists and murders orchestrated by jihadists or criminal organisations, the report mentioned.

"They are even more vulnerable because this violence goes unpunished."

The Digital Security Act is often used to keep journalists and bloggers in prison, in appalling conditions, it read.

RSF Secretary General Christophe Deloire said, "Dictatorial and authoritarian regimes are filling their prisons faster than ever by jailing journalists.

"This new record in the number of detained journalists confirms the pressing and urgent need to resist these unscrupulous governments and to extend our active solidarity to all those who embody the ideal of journalistic freedom, independence and pluralism."

The 2022 round-up figures include professional journalists, non-professional journalists and media workers.
