Israeli Prime Minister Benjamin Netanyahu said the occupied Syrian Golan Heights will remain "under Israel's sovereignty".
The Golan Heights will forever remain under Israeli sovereignty. We will never leave the Golan Heights. It's ours
Netanyahu said at a conference of Israeli youth held outside the Jewish settlement of Katzrin on the Golan.
He claimed that the alternative to Israel's withdrawal from the Golan Heights would bring "radical Islamists" to the region.
"If we are not here, radical Islam will be, and we all understand the consequences."
According to media reports, Netanyahu fears that Tel Aviv will be under international pressure to withdraw from the Golan Heights, in the event of a peaceful agreement on the future of Syria.
On Tuesday, Israel marked the 50th anniversary of the Six Day War in which Israel occupied the Sinai Peninsula, Gaza Strip, the West Bank, including Jerusalem, and the Syrian Golan Heights.
