Opposition groups in Bangladesh are threatening mass protests if the government does not explain what has happened to one of their politicians.

The Bangladesh Nationalist Party has accused security forces of abducting Ilyas Ali, a former member of parliament and a rising star of the opposition, who disappeared more than a week ago.

Ali is an outspoken critic of the government and has organised several mass protests.
