Russian authorities have clamped down on Internet freedoms and introduced “invasive surveillance” online, under the pretext of fighting extremism, Human Rights Watch (HRW) said in a report published today.

The report criticizes Russia for unjustly imprisoning dozens of people based on their activity online and for introducing new laws that give the government tools to “restrict access to information, carry out unchecked surveillance and sensor information the government designates as ‘extremist.’”
