Violence in Syria's Druze province has triggered Israeli military action, complicating relations with Turkey and creating a power vacuum that Iran could exploit.

The United States said it did not support recent Israeli strikes on Syria and had made clear its displeasure, while Syrian leader Ahmed al-Sharaa accused Israel of trying to fracture his country.

In a hardening of his rhetoric against Syria’s southern neighbour, Mr Sharaa accused Israel of seeking to foment “endless chaos”. He said Syria faced a choice between “open war with the Israeli entity” or handing security in the Sweida province over to factions from the country’s Druze minority.

Republican congressman and Israel caucus co-chair Joe Wilson rebukes Israeli military strikes on Syria, calling them insulting to Trump's recent diplomatic efforts in the region.

Hundreds of Druze from Israel pushed across the border in solidarity with their Syrian cousins they feared were under attack. Many then met relatives never seen before.

The White House is attributing the outbreak of violence in the Middle East between the Syrian government and Israel to a "misunderstanding" over ethnic grudges.

An Israeli military official said, "we are reinforcing forces in the Golan Heights and along the border, ready for a multitude of scenarios."
