UNITED NATIONS, Dec. 19 (Xinhua) -- UN Secretary-General Antonio Guterres on Thursday urged Israel to stop violations of Syria's sovereignty and territorial integrity.

Speaking at a press conference, Guterres condemned Israel's extensive airstrikes on Syria aimed at destroying strategic weapons and military infrastructure and its troops' entry into a demilitarized zone between Syria and the Israeli-occupied Golan Heights.

"They are violations of Syria's sovereignty and territorial integrity and they must stop," he said. "Let me be clear: There should be no military forces in the area of separation other than UN peacekeepers. And those peacekeepers must have freedom of movement to undertake their important work."

Guterres underscored that Israel and Syria must uphold the terms of the 1974 Disengagement of Forces Agreement, which remains fully in force.

"This is a decisive moment -- a moment of hope and history, but also one of great uncertainty," the UN chief told reporters.

"Some will try to exploit the situation for their own narrow ends. But it is the obligation of the international community to stand with the people of Syria who have suffered so much," he said. ■
