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

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.
However, Hasina's son and former government adviser, US-based Sajeeb Wazed Joy, 53, criticised the interim government as "completely powerless" and composed of "figureheads".
"Right now in Bangladesh, you have mob rule," he told AFP in an interview from Washington.
