Doctors and bankers were among the hundreds of Sri Lankans who marched on Wednesday to demand that the government resolve a severe fuel shortage at the heart of the worst economic crisis in decades or step down.

Weeks of street demonstrations against cascading woes such as power cuts and shortages of food and medicine brought a change in government last month after nine people were killed and about 300 injured in protests.

Left with just enough fuel for about a week, the government restricted supplies on Tuesday to essential services, such as trains, buses and the health sector, for two weeks. Still, doctors, nurses and medical staff say that despite being designated essential workers, they struggle to find enough fuel to get to work on time. “This is an impossible situation, the government has to give us a solution,” H. M. Mediwatta, secretary of one of Sri Lanka’s largest nursing unions, the All Island Nurses Union, told reporters.
