The leader of Russia’s Chechnya region says he has deployed his fighters to Ukraine to join battle with Russian troops, writes BBC.

In a video posted online, Ramzan Kadyrov said Chechen forces had so far successfully captured a Ukrainian military facility without suffering any casualties.

The leader of the southern Russian republic is a key ally of the Russian president.

Justifying the invasion, he says Putin’s decision to attack Ukraine will prevent Moscow’s enemies from using the country to launch an attack on Russia.

Chechen fighters loyal to Kadyrov have a notorious reputation and stand accused of human rights abuses.
