The ousted Bangladeshi Prime Minister, Sheikh Hasina, will return to the country when elections are declared, her son Sajeeb Wazed Joy says.
Ms Hasina, who resigned and fled the country earlier this week following a massive unrest, is currently in India.
Bangladeshi media say more than 500 people were killed in weeks of demonstrations against Ms Hasina. Many of them were shot by the police.
Thousands were injured in the worst violence Bangladesh has seen since its war of independence in 1971.
