Deadly clashes erupted overnight as jihadist fighters attacked two besieged regime-controlled villages in northwestern Syria, a monitor said today.
The villages of Fuaa and Kafraya represent a tiny pocket of regime-held territory in Syria's northwest Idlib province, which is otherwise almost entirely controlled by various jihadist and hardline rebels.
Occasional skirmishes erupt there but the frontline has been quiet in recent months. Late yesterday, fighters from Al-Qaeda's former Syrian affiliate attacked Fuaa and Kafraya, according to the Syrian Observatory for Human Rights.
"This is the fiercest attack in around three years," he told AFP.
The fighting, which was continuing Sunday, had killed six Syrian pro-regime fighters and at least three from HTS.
Around 10,000 people, most of them Shiite Muslims, are estimated to live in the two villages. Syrian troops also hold some territory in Idlib's east, including the key Abu Duhur airbase.
Siege tactics have been used throughout Syria's seven-year conflict, mostly by the government.
Troops have employed the tactic alongside heavy bombing to cut off food and medicine to rebel-held areas, then coerce people to agree to leave in population transfer deals. After such agreements, the United Nations no longer considers those areas as besieged.
The fate of Fuaa and Kafraya has been heavily impacted by such deals.
They made up part of the Four Towns Agreement, a complex deal that saw tit-for-tat evacuations and aid deliveries between Fuaa and Kafraya on one hand, and the government-besieged towns of Zabadani and Madaya.
Idlib, which lies on the border with Turkey, has seen its population balloon in recent years as fighters and civilians evacuated from other opposition areas are dumped there. Rebels overran most of Idlib in 2015, but the mainstream opposition's influence has dwindled as jihadists like HTS have solidified their grip on the province.
In recent months, regime forces have recaptured a sliver of the province and the Islamic State group is conducting hit-and-run attacks there against its HTS rival.
Last week, clashes in Idlib between HTS and an IS sleeper cell made up of Iraqi jihadists left more than two dozen fighters dead, mostly from IS.
In retaliation, the IS cell executed five HTS fighters it had abducted in Idlib, the Britain-based Observatory said today.
HTS also killed six IS members it had captured in the clashes.
