WASHINGTON (AP) — The State Department says Secretary of State John Kerry has pressed his Russian counterpart to make clear Moscow's commitment to end the flow of weapons and other support to separatists in Ukraine.
Kerry's call Saturday with Foreign Minister Sergey Lavrov (SEHR'-gay LAHV'-rahf) came after pro-Russia separatists downed a Ukrainian military transport plane. All 49 troops and crew members aboard were killed.
The U.S. contends Russia has sent tanks and rocket launchers to the rebels.
A State Department official says Kerry expressed "strong concern" about the shootdown and the flow of weapons and militants across the Russian-Ukraine border. Kerry also urged a fair settlement of a natural gas dispute.
Kerry also spoke with Ukraine's prime minister, Arseniy Yatsenyuk.
The official spoke on condition of anonymity to describe private calls.
