MOSCOW (Reuters) - A soldiers' rights group cast doubt on Monday on denials by military prosecutors in Moscow that a Russian serviceman was on active duty when captured fighting in Ukraine.

The Kremlin and Russia's military say Alexander Alexandrov, captured with a colleague on May 16, had quit Russia's military before going to east Ukraine to fight alongside pro-Russian separatists..
