Dr Talat Amer, a surgeon at Sweida National Hospital in southern Syria, worked tirelessly for three days as bombs fell and the building came under siege from government and militia forces.

Syria's Islamist-led government struggled to implement a ceasefire in the predominantly Druze region of Sweida on Saturday, with machinegun fire and mortar shelling ringing out after days of bloodshed.

At the center of a crisis in Syria are the Druze — a secretive religious minority that long carved out a precarious identity across Syria, Lebanon and Israel.

Syrian government forces had largely pulled out of the Druze-majority southern province of Sweida after days of clashes with militias linked to the Druze religious minority that threatened to unravel the country’s fragile post-war transition.

DAMASCUS, Syria — Renewed clashes broke out overnight between Druze armed groups and members of Bedouin clans in southern Syria, and government forces were preparing to deploy again to the area Friday after pulling out under a ceasefire agreement that halted several days of violence earlier this week, officials said.

As a fragile ceasefire holds in southern Syria following deadly clashes, a Syrian Druze writer in exile Sarah Hunaidi tells CNN it’s a “horrible situation” on the ground, as food supplies run low and hospitals remain out of service.

Israeli military responds to protect Syrian Druze from Islamist militants as local Druze citizens cross the border to aid their brethren, prompting concerns from Israeli officials.

The Druze religious sect, enmeshed in an outbreak of tit-for-tat violence in Syria, began roughly 1,000 years ago as an offshoot of Ismailism, a branch of Shiite Islam.
