Russia's communications regulator has ordered instant messaging platform Discord to delete almost 1,000 materials it deems illegal, including posts it says contain child pornography and promoting drug abuse, the TASS news agency reported on Tuesday.

San Francisco-based Discord and the regulator, Roskomnadzor, did not immediately respond to requests for comment.

Roskomnadzor is demanding the removal of 947 illegal materials, TASS cited Roskomnadzor as saying, including posts "containing child pornography, calls for extremism, the involvement of minors in illegal activity, calls for suicide, LGBT propaganda, and pro-drug content".

Russia has for several years ordered foreign technology platforms to remove content it regards as illegal, issuing relatively small, but regular fines when it sees failures to comply.

Moscow last year widened restrictions on the promotion of what it calls "LGBT propaganda" amid a broader crackdown on LGBT rights, amid a push by President Vladimir Putin to promote what he calls traditional values.

Discord has previously failed to remove banned material, Roskomnadzor noted. The platform was fined 3.5 million roubles ($37,493) on Monday over illegal content.

Russia has in the past banned social media platforms that fail to comply with its rules on content.
