China hit Telegram with cyber attacks during the massive Hong Kong protests on Wednesday.
According to a tweet from the encrypted messaging app's CEO Pavel Durov, the firm was hit with powerful denial-of-service attacks originating mostly from Chinese IP addresses that coincided with the large-scale protests in Hong Kong against a proposed new extradition law.
Organizers have said that up to 1 million of Hong Kong's 7.4 million residents flooded the streets on June 9 to protest the extradition law, which would make it much easier for Chinese authorities to arrest people in Hong Kong.
Demonstrators have used messaging apps, including Telegram, to organize themselves, according to The Next Web.
When the United Kingdom relinquished authority over Hong Kong in 1997, the principle of "one country, two systems" was promised to its citizens as a way to ensure its democratic system would prevail despite China's communist dictatorship.
Human rights groups have decried the police use of force to crack down on demonstrators, who have been largely peaceful.
“Hong Kong authorities shouldn’t use unlawful force to suppress peaceful protests,” said Sophie Richardson, China director at Human Rights Watch, in a statement. “The authorities should recognize Hong Kong’s legal obligations to allow people to make their views known through peaceful protests.”
