Syria’s leadership can make a real contribution to the struggle against the Daesh extremist group and Russia considers it is important in this regard to encourage settlement in Syria, Kremlin aide Yuri Ushakov told TASS on Monday.

Russia believes that any opening opportunities should be used for establishing a dialogue between Damascus and all the interested parties, including Saudi Arabia, Ushakov said adding that the Kremlin hopes such an approach will be backed.

Moscow is "seriously concerned about the growing threat to stability in the Middle East" amid the activity of the Islamic State group that "controls a significant part of Syria and Iraq, including important facilities of the economic infrastructure of these countries," Ushakov said.

"The Islamic State has a military and political initiative and has stepped up activity in the northern provinces of Afghanistan, on the territory of Libya, Central Asia countries and even North Caucasus," he stressed.

The efforts of the US-led international coalition against the radical Islamists and extremists clearly show that "airstrikes alone do not lead to a decisive success in the fight against gunmen," he said.

The Kremlin aide has not ruled out that contacts of the representatives of the Syrian leadership with the countries involved in the conflict, including Saudi Arabia, can take place in the near future.

"Taking into consideration the extremely dangerous situation, one should forget the offense, alleviate the existing contradictions and unite efforts for the fight against the Daesh," Ushakov said.
