Russia insists that double standards be abandoned for effectively combating the Islamic State on Iraq and Syria (ISIS) and that President Bashar al-Assad be taken as a partner in this effort, said Russian Foreign Minister Sergey Lavrov.

In an interview with the Russian 1 TV channel, Lavrov noted that he discussed with his U.S. counterpart John Kerry issues related to the initiative of Russian President Vladimir Putin on forming a unified front for fighting ISIS, “and as it is in all other cases, we only suggest presenting clear views if we all want to not give ISIS the chance to realize its wicked idea of creating a caliphate.”

The Russian invitation, Lavrov said, has received wide attention in the international arena, noting that the Syrian government is willing to participate in the international efforts to fight ISIS.

He pointed out that Russia has suggested to Washington and its other partners fighting ISIS through establishing an alliance and supporting the political solution in Syria at the same time.

He warned of the U.S. attitude, saying “the US could blow up the situation in Syria if it would defend the opposition that it has trained,” calling for avoiding allegations and presenting only facts by those who allege that Syria still has chemical weapons.
