Huge swathes of Bangladesh were left without power on Tuesday after a partial failure in the national electricity grid.
According to sources, the authorities were working to gradually restore power supply in the country of 168 million people.

The country's power grid malfunctioned at around 2 p.m. on Tuesday, leading to blackouts across 75-80% of the Bangladesh, said Bangladesh Power Development Board official Shameem Hasan to Reuters. 

"We are trying to restore the system," Hasan said, while adding that utilities were currently producing around 4,500 MW of power, in comparison to nationwide demand of 14,200 MW.

An investigation is underway to find out the reason behind the grid's collapse, Hasan said.
