"Developments in the situation in the Middle East give rise to concern and growing disquiet," foreign ministry spokesman Alexander Yakovenko said in a statement.

With Israel not ruling out further incursions into Syrian territory, Yakovenko said Moscow considered such actions as "leading to an extension of the framework of the confrontation, likely to draw in other countries and to lead to more dramatic consequences."

Moscow "insistently calls on all the parties to the conflict to display the greatest restraint, to act reasonably and responsibly," he said.

The latest developments "require the international community to take more energetic measures to avert an even more dangerious deterioration in the situation," the statement said.

Israel ordered the attack, the first strike so deep into Syrian territory since the Yom Kippur war 30 years ago, overnight Saturday in response to a deadly suicide bombing earlier in the day by the Palestinian militant group Islamic Jihad that left 19 people dead.
