Hundreds of millions of people have been left without electricity in northern and eastern India after a massive power breakdown.

More than half the country has been left without power after three grids collapsed, one for a second day.

The country's power minister has blamed the crisis on states drawing too much power from the national grid.

Hundreds of trains have come to a standstill, traffic lights have failed and hospitals are running on backup generators.
