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.

A string of prominent secular bloggers have been attacked or killed by religious extremists in Bangladesh in the last year.

Bangladesh is officially secular but critics say the government has failed to properly address the attacks.

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.

Last year, four prominent secular bloggers were killed with machetes, one inside his own home.
