Ukrainian Foreign Minister Dmytro Kuleba has called on the international community to respond to the "lawlessness of the Russian authorities" regarding the mass arrests of protesters, against the imprisonment of Russian opposition leader Alexei Navalny.

"Russian authorities hit a new lawlessness record by poisoning, then imprisoning Navalny, mass detentions of peaceful protestors in Russian cities. Clearly, Russia isn't willing to respect human rights & freedoms. Must be forced then. This is the task for international community," Kuleba wrote on Twitter in the early hours of Wednesday.
