Russia said on Monday it would extend a punitive slowdown of Twitter until May 15, though it acknowledged the US social media company had speeded up deletion of what Moscow calls banned content.
Moscow has traditionally taken a more hands-off role in policing the internet than neighbouring China. But as friction has grown this year over the arrest and jailing of Kremlin critic Alexei Navalny, it has signalled a tougher line.
Russia has since March impeded the speed of Twitter for not removing content it deems illegal, and threatened to block it entirely. Photos and videos take longer to load for some users.
