Russia has denounced the Western countries double-standards by supporting militants in one country and fighting them in another.
"It is hard to call as far-sighted the policy which on substance either mounts military persistence as in Mali, or provides to the same groups support as in Syria," said Russian Foreign Minister Sergey Lavrov at the annual General Debate of the UN General Assembly, which entered its fourth day in New York on Friday.
Lavrov warned against the rising of extremism in the world, saying the struggle of democracies against tyrannies or the good against the evil has long obscured the problems associated with the rising wave of extremism, which spills over to other regions today as well.
The Russian foreign minister also criticized the West for accusing the government of Syrian President Bashar al-Assad of using chemical weapons on its own people without proof.
"The use of chemical weapons is inadmissible. This does not mean, however, that one can usurp the right to accuse and pass verdicts."
"All the incidents associated with the use of chemical weapons by whoever that might be in Syria must be investigated in a professional and unbiased manner," Lavrov said.
Syria has been gripped by deadly unrest since 2011. According to reports, the Western powers and their regional allies -- especially Qatar, Saudi Arabia, and Turkey -- are supporting the militants operating inside Syria.
In a recent statement, the United Nations High Commissioner for Refugees said the number of Syrian refugees, who have fled the countrys 29-month-long conflict, reached two million.
