The Israeli military says its fighter jets have struck weapons depots and command centers belonging to Hezbollah in Syria.
The Israeli military made a rare statement saying it had hit "weapons storage facilities and command centers" belonging to Hezbollah’s elite Radwan Force and the group’s armament unit in the al-Qusayr area, close to Lebanon’s border with Syria.
According to Syrian state media, a number of civilians were wounded and material damage was caused by the Israeli strikes in Homs province.
Earlier in the day, a Hezbollah attack on northern Israel's Metula killed five people, including an Israeli farmer and four foreign workers, as Lebanon said Israeli strikes killed six health workers in the country's south.
US envoys and Israeli officials were due to meet in Israel on Thursday to discuss efforts towards a ceasefire in both Lebanon, where Israeli forces are battling Iran-backed Hezbollah, and in Gaza, where they are fighting Iran-backed Hamas.
The United States will help oversee a Hezbollah-Israel ceasefire by which UN forces and the Lebanese army replace the Iran-backed group in the south of the country, according to an unverified draft published by Israel's Channel 11.
Israel has been carrying out strikes against Iranian-linked targets in Syria for more than a decade as Iran has increased its presence since the Syrian civil war began in 2011.
Raids have also ramped up since last year's October 7 attack on Israel by Palestinian militant group Hamas sparked the Gaza war. Iranian-backed militants from Syria, along with countries such as Iraq and Yemen, have been acting against Israel since October 7, in allegiance with Hamas after its invasion of Israel.
