Syrian air defenses responded to alleged Israeli airstrikes targeting Syria's T4 airbase near Homs, western Syria on Friday night, Lebanese news site Al-Mayadeen reported.
Hezbollah and Iran hold a notable military presence at the airbase, according to Army Radio.
Two members of pro-Iranian militias were killed in the attack, the Syrian Observatory for Human Rights reported Saturday.
According to the Lebanese reports, most Israeli missiles were shot down by the Syrian air defenses. The Syrian army confirmed the attack, adding that six Syrian soldiers were injured by the airstrikes and damage has been caused to military equipment.
Earlier on Friday, unidentified aircraft targeted military sites belonging to Iranian militias in Al Bukamal and Deir ez-Zor, Syria, the Syrian Observatory for Human Rights (SOHR) reported.
A fire reportedly broke out at one site, which is in the vicinity of a hospital.
Al Bukamal, near the country's border with Iraq, is under a "state of alert," according to SOHR, as intense shooting was heard throughout the city, reportedly an attempt by the Iranian militia to target the unidentified aircraft.
In August, four pro-Iranian fighters allied with the Assad regime were killed as alleged Israeli airstrikes targeted Syrian military sites in the Qalamoun Mountains, near the capital of Damascus.
The IDF allegedly struck the T4 airbase in 2019, targeting warehouses at an Iranian Revolutionary Guard Corps military base and killing five Syrian soldiers in the process.
