Germany adds new twist to Litvinenko case?

Investigative committee spokesman Vladimir Markin said: “During a meeting with our colleagues in Hamburg we received documents that are of interest concerning the investigation into the murder of Litvinenko,” he said.

Germany has also provided information on the alleged murder attempt of Dmitry Kovtun – a businessman who met Litvinenko in London before his death.

Russian investigators have been in Hamburg for almost two weeks probing the case.

Aleksandr Litvinenko was poisoned by a radioactive substance known as Polonium 210 in London in November 2006.

Dmitry Kovtun was also hospitalised due to polonium poisoning but managed to recover.
