Israeli regime has refused to comply with a recent ceasefire brokered by the U.S. and Russia which went into effect in southwestern Syria on Sunday, saying it would act to protect its interests.

“Israel reserves its complete freedom of action, regardless of any understandings or developments,” minister of military affairs Avigdor Liberman said on Sunday.

The U.S., Russia and Jordan agreed to back a ceasefire that aims at establishing a de-escalation zone in Syrian province of Dara’a, Suwayda and Quneitra, bordering the Israeli-occupied Golan Heights.

The agreement was announced on Friday following a meeting between Russian President Vladimir Putin and his American counterpart, Donald Trump, on the sidelines of the G20 summit in Hamburg, Germany.

Israeli Prime Minister Benjamin Netanyahu commented on the ceasefire, saying Tel Aviv will carefully monitor the developments in Syria, while “strongly upholding our red lines.”

Syria has been suffering from foreign-backed militancy since the beginning of a conflict in 2011. Since the beginning of the conflict, hundreds of thousands of civilians have been killed.

The Syrian government says Tel Aviv and its Western and regional allies are propping up militant groups against the Syrian government.

Israel also regularly targets Syrian army’s positions in the Golan Heights, describing the attacks as retaliatory.
