The coalition strikes occurred in the area of an established "deconfliction zone" with Russia, where US' and British special operations forces have been training Syrian rebel fighters near the border with Iraq and Jordan. Russia slammed that move as a violation of international law.
"The current situation shows the shortcomings in the current situation with coordination and actions of those who counter terrorism in Syria," he said.
Speaking about the Kurds, the minister said that they were not included in the list of groups invited to the Geneva talks on Syrian settlement through UN Special Envoy Staffan de Mistura because "some participants of the talks impede it," despite the Kurds being "an objective force on the ground" and part of the Syrian state.
"Neither fighting the terrorists, nor discussing the Syrian constitutional system is possible without the Kurds," Lavrov stressed.
The sixth round of the intra-Syrian talks in Geneva held under the auspices of the United Nations took place on May 16-19.
