Chechnya leader to give evidence
Chechnya's leader said he is ready to give evidence in the investigation into the murder of Russian opposition leader Boris Nemtsov.
The main suspect in the February 27 killing is an officer in Ramzan Kadyrov's security force, and Nemtsov's children have asked for Kadyrov to be questioned.
Kadyrov said his officer, Zaur Dadaev, should be sent to prison if found guilty of shooting Nemtsov.
After Dadaev's arrest, Kadyrov described him as a brave soldier.
