The Ukraine anti-protest law also abolishes fair trials and imposes arbitrary censorship.

It also bans collecting information about thugs, which I presume includes photos or videos of what they do. In the US, that's not illegal, but the thugs wish it were, so they fabricate accusations against those who take photos.

Thugs have been fighting with protesters in Kiev, and the protesters have been fighting back.

Subsequently a truce was agreed, for talks between the president and the opposition. However, no deal was reached.

This report claims that the violence was started by right-wing infiltrators. I have no way to evaluate this claim.
