A Ukrainian military pilot blamed by Russia over the 2014 downing of Malaysian Airlines flight MH17 has killed himself, Ukrainian media report, quoting police.
Capt Vladyslav Voloshyn had called the Russian allegation a lie. Dutch investigators concluded that a Russian Buk missile had destroyed the Boeing 777 jet, killing 298 people.
Reports say Voloshyn shot himself at home in Mykolaiv, near the Black Sea.
Ukraine described him as a war hero.
He had flown 33 combat missions in a low-flying Su-25 ground attack jet against Russian-backed separatist rebels in eastern Ukraine, and had been granted a medal for bravery.
Recently the 29-year-old had been in charge of the Mykolaiv airport, after resigning from the air force. The southern city near Odessa is called Nikolayev by Russian speakers.
