Kiev on Wednesday urged Russia to admit responsibility over the 2014 downing of passenger flight MH17 over rebel-held eastern Ukraine that left 298 people dead, after charges were laid by international investigators.
"We call on the Russian Federation to acknowledge its responsibility for supplying arms" to Kremlin-backed rebels in the region, Ukraine's foreign ministry said in a statement.
It urged Moscow "to cooperate with the probe", referring to international investigators who earlier issued arrest warrants for four suspects, three of them Russian nationals.
