MOSCOW, May 30. /TASS/. Turkey should prove its claims that Moscow allegedly supplies weapons to the Kurdistan Workers’ Party, Russian president’s special envoy for the Middle East and Africa, Deputy Foreign Minister Mikhail Bogdanov told journalists on Monday.
"When somebody alleges anything, he must present the evidence," he said, answering a corresponding question.
Earlier on Monday, Turkish President Tayyip Recep Erdogan accused Moscow of attempts to supply air defense systems to the Kurdistan Workers’ Party that is outlawed in Turkey.
According to the diplomat, Turkey has no legal grounds to take part in an antiterrorist operation in Syria jointly with the United States.
"On what grounds?" he said, answering a corresponding question. The high-ranking diplomat said that such actions "should be based on resolutions and decisions of the UN Security Council or it is necessary to agree with the Syrian authorities."
"It’s interference in the affairs of sovereign states and in an internal conflict," Bogdanov said.
According to previous reports, Ankara proposed to Washington to conduct a joint military operation in Syria without Kurds.
