Sri Lanka, a country of 22 million people, is under the grip of an unprecedented economic turmoil, the worst in seven decades, leaving millions struggling to buy food, medicine, fuel and other essentials.

Tens of thousands have taken to the streets in recent months, calling for the country's leaders to resign over accusations of economic mismanagement.

Schools have been suspended and fuel has been limited to essential services. Patients are unable to travel to hospitals due to the fuel shortage and food prices are soaring.

In several major cities, including Colombo, hundreds are forced to stand in line for hours to buy fuel, sometimes clashing with police and the military as they wait.

The country, with an acute foreign currency crisis that resulted in foreign debt default, had announced in April that it is suspending nearly USD 7 billion foreign debt repayment due for this year out of about USD 25 billion due through 2026. Sri Lanka's total foreign debt stands at USD 51 billion.
