"The FTS considers the Taliban's announcement of the interim government to be illegal and a clear sign of the movement's hostility towards the Afghan people," the statement said on Twitter.
As noted, the Taliban's presence in power poses a "threat to the stability and security of Afghanistan, the region and the world."
The statement emphasizes that legitimate tenure in power can only be achieved through popular vote in general elections.
Earlier, the Taliban announced the composition of the new government.
Press Secretary of the Russian President Dmitry Peskov announced Russia's intention to monitor the actions of the Taliban government.
