Opposition member Ilya Yashin has written an open letter to the head of the Chechen government, Ramzan Kadyrov, expressing his willingness to visit Kadyrov in Grozny, Chechnya's capital, to discuss the murder of Boris Nemtsov.

“I am ready to come to Grozny. I request you meet with me. I have a number of questions, which you will not like. State-sponsored media portray you as a man who is not afraid of a direct conversation and hard questions. I hope you live up to your reputation,” Yashin wrote.

Kadyrov's press office says it's unaware of Yashin's letter.

Boris Nemtsov, was shot dead in Moscow on February 27, 2015. Five people were arrested on suspicion of his murder. Among the five is a former member of the Chechen “Sever” battalion, Zaur Dadaev, who is considered the primary suspect. Investigators believe Ruslan Muhudinova ordered the killing, and he has been arrested in absentia.

In early October, Ramzan Kadyrov invited Zhanna Nemtsova, the daughter of the murdered politician, to Chechnya. She wants investigators to question Kadyrov, who promised to come in for questioning, if the Investigative Committee summons him.
