Turkey prosecutes suspected killer of Russian pilot: official

ISTANBUL (Reuters) - A man suspected of killing a Russian air force pilot after his plane was shot down by a Turkish jet near the Syrian border last November is being prosecuted, a Turkish official said on Monday. Alparslan Celik, who was fighting with a Turkish-backed Turkmen brigade opposing government forces in northern Syria at the time, was detained at the end of March in the Aegean coastal city of Izmir on unrelated charges, but a court decided in May there was insufficient evidence against him. Celik's prosecution was long demanded by Moscow. The Kremlin said earlier that Turkish President Tayyip Erdogan had apologized in a letter to Russian leader Vladimir Putin over the downing of the jet.
