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 leaders of Israel and Syria have agreed to a ceasefire days after major Israeli strikes, a US envoy said Friday, as he urged all sides in war-torn Syria to lay down arms.

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.

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 conflict drew airstrikes against Syrian forces by neighboring Israel in defense of the Druze minority before most of the fighting was halted by a truce announced Wednesday.

Clashes that shook southern Syria this week have killed hundreds of people, including civilians, and drawn in an array of both local and international players, harking back to the dynamics of the country's nearly 14-year civil war.

Syria says it is withdrawing troops from a flashpoint southern city after days of deadly clashes with an Arab minority group that triggered military action from Israel.

The Israel Defense Forces said it struck "the entrance" of Syria's military headquarters in Damascus on Wednesday.
