The airstrikes were conducted deep into Syria, in northern Syria's Aleppo province, and left over 40 people dead. This reportedly included Syrian soldiers, Hezbollah militants, and civilians. Most international reports are saying 42 were killed, but the Syrian government did not initially give a precise casualty count.

The anti-Assad opposition and UK-based organization Syrian Observatory for Human Rights (SOHR) described that the Aleppo attack left the highest number of dead among Syrian soldiers in a single such Israeli attack. While Israel doesn't typically directly own up to or confirm such attacks on Syrian soil, its military has been conducting sporadic attacks on Syria going back years.

The attack happened in the pre-dawn, overnight hours - with state-run SANA emphasizing that many civilians were killed and wounded, but without giving a figure.

Syria's defense ministry pointed to the airstrikes having some level of coordination from "terrorist organizations" on the ground which "in conjunction" to the air raid carried out drone attacks, presumably from Al-Qaeda (Hay'at Tahrir al-Sham) occupied Idlib. Some reports are saying that Israeli warplanes hit a "Hezbollah warehouse" - though there's no ground confirmation of this.

This new major attack comes the day after Israeli airstrikes on a suburb of Damascus, which reportedly wounded two civilians. Israeli officials and media have long claimed to be waging a campaign against Iranian and IRGC operatives and assets in Syria.
