TASS- The Russian top diplomat also doubts that the Trump administration will stick to its campaign slogans about Iran

"I don�t think that the Trump administration is thinking in the same terms as the slogans during the campaign, that Iran is the number one terrorist state; we don�t have a single fact to substantiate this claim," Lavrov said.

"At least when we were facing a huge terrorist threat, when we were under terrorist attack in the 1990s in the northern Caucasus, we detected and discovered dozens and hundreds of foreign terrorist fighters from very close neighborship to Iran, but not from Iran at all," he said. "And we know that the political circles in quite a number of countries were really encouraging these terrorist groups to go into the northern Caucasus."

"Iran had never challenged the sovereignty of the Russian Federation, never used its own links with Muslim groups to provoke radicalism and to cause trouble," he added.

Russia, Iran and those that cooperate with the Syrian army, "are fighting terrorists in Syria," he said.

"Iran is a powerful player on the ground, legally invited by the government. Iran has influence over the Lebanese Hezbollah, which is also legitimately on the ground," the Russian foreign minister said. "And if we all want, you know, to topple, to defeat terrorists in Syria, there should be some coordination."
