Super-cyclone Amphan kills up to 20 in India and Bangladesh

Strong winds tore down electricity pylons, walls and buildings, with full scale of damage still being estimated

The most powerful cyclone to hit Bangladesh and eastern India in more than 20 years tore down homes, carried cars down flooded streets and claimed the lives of up to 20 people.

Authorities began surveying the damage Thursday after millions spent a sleepless night which saw 165km/h (102mph) winds carrying away trees, electricity pylons, walls and roofs, and transformer stations exploding.
