Half of India Without Power As Blackout Continues for a Second Day
Whole grids have shut down and public transport in major cities has stopped.
A massive power breakdown has hit India for a second day running, leaving more than half the country without power.
Officials said the northern and eastern grids had both collapsed. All Delhi metro services have been halted and staff are trying to evacuate trains.
Monday's power failure caused severe disruption and travel chaos across northern India.
It was unclear why the grid collapsed but the power minister said some states may have been taking too much power.
