NEW DELHI: The son of Bangladesh's toppled autocratic leader thanked New Delhi on Sunday (Aug 11) for "saving her life", accused caretaker authorities of allowing "mob rule" and warned of chaos ahead without swift elections.

Sheikh Hasina, 76, quit as prime minister on Monday after a student-led uprising and fled by helicopter to longtime ally India.

Her government was accused of widespread human rights abuses, including the extrajudicial killing of thousands of her political opponents during her 15-year tenure.

The military announced her resignation and then agreed to student demands that Nobel Peace Prize winner Muhammad Yunus, 84, lead a caretaker administration, charged with ending disorder and enacting democratic reforms.
