One of four suspects on trial for the 2014 downing of Malaysia Airlines Flight 17 has denied any involvement with firing or supplying the missile allegedly used in its destruction, a lawyer said in court on Monday. MH17 was flying from Amsterdam to Kuala Lumpur when it was shot down by a missile fired from territory held by pro-Russian rebels during fighting in eastern Ukraine, international investigators say. One defendant, Oleg Pulatov, has instructed a lawyer to defend him.
