Sri Lanka’s parliament has canceled its remaining sittings for the week to save fuel, officials said on Thursday, with a disastrous economic crisis rapidly depleting the island nation’s already scarce petrol supplies.

A foreign currency shortage has prevented the import of food, oil, and medicines, while runaway inflation and regular blackouts have made life miserable for Sri Lanka’s 22 million population.

Parliamentary officials said lawmakers decided to cancel sessions on Thursday and Friday to avoid unnecessary petrol use, days after authorities closed schools and some state offices for the same reason.

Energy Minister Kanchana Wijesekera said a gasoline shipment that was due on Thursday had been delayed and urged motorists to cut down on travel.

“Only limited amounts of petrol will be distributed to pumping stations today and tomorrow,” he told reporters in Colombo, with motorists already waiting in line for days to top up their tanks.
