A Bangladeshi law student who had expressed secular views online has been killed in the capital, Dhaka.

Nazimuddin Samad was hacked with machetes at a traffic junction late on Wednesday and then shot, police said.

The 28-year-old was reported to have been an organiser of the Ganajagran Manch, a secular campaigning group.

Religious extremists in Bangladesh in the last year attacked or killed a string of prominent secular bloggers. Bangladesh is officially secular but critics say the government has failed to arrest the assailants.

Police said three assailants on a motorcycle attacked Mr Samad and then shot him, The Dhaka Tribune reported.

Police have not named any suspects in the case nor confirmed a religious motive.
