GROZNY, June 18. /TASS/. Chechnya’s head Ramzan Kadyrov believes that the clues to solving the murder of Russia’s oppositional politician Boris Nemtsov should be looked for in Ukraine and the United States.

"I believe that the traces should be looked for not in Chechnya, but in Ukraine, the Ukrainian security service and also in the United States. There are too many signs indicating that the man behind the killing is Adam Osmayev, who is currently in charge of Ukraine’s Johar Dudayev Battalion," Kadyrov said according to his press office.

"Dadayev (the key person accused of the murder) was detained in Ingushetia, and, as his defence lawyers claims, has been repeatedly beaten up. A friend of his was detained with him and to secure his release Dadayev agreed to confess," Kadyrov said.

"The masterminds of the murder first used Nemtsov, then liquidated him, and are now trying to put the blame at somebody else’s door," Kadyrov said.

"Rumour has it I said once Nemtsov should be killed. That is not true! Why should’ve we wished to see him dead? What had he done to us? Was he a hindrance? He hadn’t visited us for many years. Last time I saw him was fourteen years ago in Gudermes," Kadyrov said.

Boris Nemtsov, a co-chairman of the RPR-Parnas party, member of the Yaroslavl Region’s legislature, was gunned down on a bridge in the centre of Moscow on February 27 minutes before midnight. Four suspects have been arrested since: Zaur Dadayev, who, the investigators believe, was the one who pulled the trigger, and also Khamzat Bakhayev, the Gubashev brothers (Anzor and Shadid), and Tamerlan Eskerkhanov. A Moscow court last April prolonged their custody till August 28.
