The second day of the main hearings on extradition of Chechen militants' emissary Akhmed Zakayev to Russia will be held in London on Tuesday.
Today's trial is expected to thoroughly consider the fate of Chechen leaders, arrested and convicted by Russian authorities at different times.
Apart from this, the court intends to hear four witnesses. Among them are two British experts, Professor John Russell and former BBC political observer Thomas de Waal, as well as two witnesses from Russia, whose names have not been announced yet.
During the first day of the hearings on Monday former deputy prime minister of Maskhadov's Chechen government Akhmed Zakayev was charged with 13 counts. The counts of the indictment include murder, terrorism and hostage taking.
US and Chinese experts believe that the Sukhoi Checkmate aircraft will become competition to their F-35 and FC-31 fighter jets in the arms market.
