DOHA, August 3. /TASS/. The terrorist group Islamic State (IS) might have seized more territories if Russia would not have offered military assistance to the Syrian and Iraqi governments, Russian Foreign Minister Sergei Lavrov said on Monday.

"The most serious threat in Iraq and Syria is Islamic State," he said. "Yes, we do offer military technical assistance to the Syrian government to repel this threat, we also support Iraq. We have reasons to think that without such assistance Islamic State might have seized much more thousands of square kilometres of territories."
