The Anti-Corruption Commission said Thursday it will investigate Hasina and five other family members for allegedly misappropriating government land in Purbachal

DHAKA, Bangladesh — Bangladesh has sent a formal request to India to extradite ousted Prime Minister Sheikh Hasina, who fled to New Delhi in August amid the student-led protests that ended her 15 years in power, the country’s foreign affairs adviser said Monday.

Ties between the South Asian neighbours, who have strong trade and cultural links, have become fraught since Hasina was ousted following violent protests against her rule and she took refuge across the border.
