Ukraine on Monday showed two prisoners it said were Russian soldiers who had killed Ukrainian troops in fighting in its east and said they would be prosecuted for ¡°terrorist acts.¡±

The Ukrainians seized on the capture of the two Russians, both wounded, to support their accusations of direct Russian involvement in the separatist conflict despite a cease-fire signed in February. Russia denies active military involvement.

In a video posted online by the Ukrainian interior ministry, one of the prisoners gave his name as Alexander Alexandrov. He said he had been on a spying mission in Ukraine as part of a 14-member special forces group from the Russian town of Togliatti.
