Israel advances to protect its borders with Syria, and Trump calls Turkey a "key player in shaping the post-Assad political landscape."

Israeli fighter jets have launched hundreds of airstrikes, while soldiers have seized a buffer zone and captured military posts in territory formerly under Syrian control.

Prime Minister Benjamin Netanyahu says Israeli troops will remain in Syrian territory indefinitely, and that blurs the border with Israel's northern neighbor.

Since the Assad regime imploded less than two weeks ago, Israel’s military has seized a strategic mountain top in its contested border area with Syria and advanced on positions beyond it, reshaping the frontier between the foes potentially for the long term.

The Israeli military hit weapons depots and air defenses, according to the Syrian Observatory for Human Rights. Israel has said it aims to keep military equipment away from extremists.
