Sri Lanka temporarily blocked all social media on Sunday after growing protests and outbreaks of violence over rising fuel and food prices.
This was confirmed by a government spokesman;
Among others, Facebook, Twitter and YouTube were affected.
This is apparently intended to prevent further protests.
President Gotabaya Rajapaksa declared a national emergency after violent protests in front of his house on Saturday.
A curfew was later imposed for 36 hours, which should apply until tomorrow Monday.
With the declaration of a national emergency that went into effect on Saturday, the President now has sweeping security powers.
The armed forces also now have powers that the police usually have to arrest and detain people.
The ban on going out was already checked nationwide on Saturday, and 664 people were arrested for violations.
In the past few weeks, there have been mainly smaller protests across the country.
Because in the island state south of India there is a great shortage of fuel for power generation.
There are currently hour-long power outages every day.
Food prices have also risen sharply.
The country is heavily indebted and desperately needs American dollars to import fuel, gas, food and medicines from abroad.
Sri Lanka has asked India and China for help in sourcing food and fuel, and has also asked the International Monetary Fund for financial assistance.
