Syria’s new authorities launched an operation Thursday against militias aligned with ousted President Bashar al-Assad, according to state news agency SANA. The reports said the operation was focused in the western province of Tartous, and that some militia members had been killed. The development came a day after pro-Assad fighters killed 14 members of the rebel group that led the offensive that pushed Assad from power. Syria’s new interior minister said on Telegram that 10 other people were wounded in what he called an “ambush,” and he vowed to crack down on anyone who undermines Syria’s security.
