COLOMBO, Sri Lanka -- Days after bomb blasts killed more than 300 people across Sri Lanka, Facebook and other top social-media platforms remained blocked in one of the largest experiments in government control over social media. While some citizens said they welcomed the restrictions, others said they had found workarounds.

Security officials are worried the Easter Sunday morning attacks -- which targeted churches and tourists across the country -- could trigger rumors, backlash, riots or even retaliation. So the government shut down Facebook, its WhatsApp and Instagram apps, Google Inc's YouTube, and even Snap Inc.'s Snapchat to create a speed bump for hate speech and false reports.

Prime Minister Ranil Wickremesinghe speaking to news media Tuesday declined to say when the blocks would be lifted. "We went through this exercise earlier," he said, referring to a similar shutdown a year ago amid heightened interreligious tensions, "and we didn't want to take another chance."

A Facebook Inc. spokeswoman didn't immediately respond to a question about how long the block on its services might last. A Google spokesman declined to comment. A spokeswoman for Twitter, which remains accessible, didn't immediately respond to a request for comment.

Pathmasiri Haputhanthiriga, the owner of a mobile-phone accessories shop said the block had slowed his business by blocking his regular use of WhatsApp to communicate, but he thought it was worth the sacrifice. "For information, slower is better," he said, referring to the blocks on the flow of social-media chatter after the attacks.

Governments around the world and technology companies are struggling to stem the flow of hate speech as well as false information following abuses such as foreign interference in U.S. elections. Facebook CEO Mark Zuckerberg has embraced stricter content-moderation requirements and last month said global regulators should take a "more active role" in governing the web.

Extremists have used Facebook to stoke violence, including in Sri Lanka and Myanmar. In India, the government has proposed forcing WhatsApp to break encrypted messages to find people who send objectionable content after more than 20 people were killed last year in mob violence following rumors spread through the app. A number of nations are focusing on gaps in social media companies' monitoring of posts and are seeking to impose regulations on them.

Sri Lanka has been a trailblazer in the battle rein in the impact of social media. In March 2018 there was a flare up in tensions between Muslims and Buddhists in some regions of the country. People spread false reports and organized attacks through social media, and the government sought ways to stop the spread of violence.

Facebook, WhatsApp, YouTube and other platforms were blocked in part or all of the country for days. The violence subsided. Many felt the reaction was a heavy-handed move -- but it succeeded.

After Sunday's attacks, the government wasted no time in blocking popular platforms again, according to NetBlocks, a London-based digital-rights group, and other internet monitoring groups. Facebook and other platforms remain inaccessible or too sluggish to use, according to consumers.

Rizvi Arif, an Uber driver in Colombo who is Muslim, said he had always felt safe in Sri Lanka but wondered what kind of backlash misinformation could cause for his community. He has stopped going to the mosque to pray, worried about retaliation from someone misled by all the misinformation on the internet. His family now just prays at home.

"I hate Facebook and WhatsApp," he said. "Sometimes, for emergencies, it's OK" to block such platforms, he said.

To be sure, rumors have still spread in the wake of bombings, but via word of mouth or television, users note. One rumor that circulated online incorrectly claimed that the safe demolition of a bomb by police was an attack. Another rumor spread by word of mouth claimed that drinking water in the country had been poisoned.

People have been circumventing the government blocks by using virtual private networks, or VPNs, which reroute traffic so authorities can't tell where users are logging on from.

University student Mohammed Afrid said he is ignoring government government suggestions not to use VPNs and employing one to get the latest news and interact with others. "We need them to get information" about what's happening following the attacks, he said. "Without communication, it's like my body doesn't work."

One of the hardest-hit churches -- St. Sebastian's church which lost more than 100 worshipers in the attack -- decided to use a VPN to post photos of the destruction on its Facebook page to ask for help and prayers.

"I just got a VPN because all social media is blocked," said the Rev. Edmond Tillekeratne, social communications director for the Archdiocese of Colombo."The truth has to go out."

Some are finding a silver lining in the crackdown. Mr. Haputhanthiriga, the shop owner, said his daughters are typically glued to their smartphones but have been forced into old-fashioned social interaction.

"They are talking now," he said, smiling. "We get to have a conversation."
