Four pro-Iranian Syrian fighters were killed before dawn today in Israeli strikes east of Aleppo in northern Syria, the Syrian Observatory for Human Rights said.

In Damascus, the official Syrian news agency SANA reported, citing a military source, that “soldiers were wounded and damaged by an Israeli enemy airstrike against locations in the districts of Aleppo (north) and Idlib (northwest) at around 00:45 (local time) time and Greece time)”.

“Four pro-Iranian fighters of Syrian nationality were killed by Israeli strikes against a scientific research center and warehouses near Safira, east of Aleppo,” the Observatory said.

The NGO, which is based in the United Kingdom but has an extensive network of sources in Syria, also claimed one death in two other raids further west targeting Saraqeb in Idlib province.

According to the Observatory, the raids near Saraqeb targeted two Syrian forces headquarters in which members of the Lebanese Hezbollah have taken positions, near the front line with the Islamist rebel group Hayat Tahrir al-Sham (HTS).

HTS, which has emerged from the former Syrian branch of al-Qaeda, controls the last pocket of armed resistance to the Syrian regime of Bashar al-Assad, which includes a large part of Idlib province and areas bordering it in provinces of Aleppo, Hama and Latakia.
