Demanding electoral reforms, hundreds of people have marched through the streets of the Bangladeshi capital, Dhaka.
But as opposition activists also enforced a countrywide transport shutdown, the situation turned violent, resulting in at least two deaths and hundreds of injuries.

Millions of people were left stranded as most trains, buses and ferries lay idle.
