DAMASCUS, Syria — Israel carried out at least two airstrikes on a western neighborhood of Damascus and one of the capital’s suburbs Thursday, killing at least 15 people and wounding another 16, Syria’s state news agency said.

The airstrikes on the Mazzeh neighborhood in Damascus and the suburb of Qudsaya, northwest of the capital, struck two buildings, the SANA news agency said.

The Israeli military said it had hit infrastructure sites and command centers of the Islamic Jihad militant group in Syria, and had “inflicted significant damage to the terrorist organization’s command center and to its operatives.”

The airstrikes in Damascus and the nearby suburb came shortly before Ali Larijani, an adviser to Iran’s supreme leader, Ali Khamenei, was scheduled to meet in the Syrian capital with representatives of Palestinian factions at the Iranian Embassy in Mazzeh.

The Israeli military said Islamic Jihad had participated alongside Hamas, the Iran-backed Palestinian militant group in the Gaza Strip, in the Oct. 7, 2023, attacks on southern Israel that killed some 1,200 people — mostly civilians — and saw 250 others abducted into Gaza.

Israel’s retaliation to the Oct. 7 attack and the ensuing Israel-Hamas war has spilled into the wider region, affecting Lebanon, Syria and leading to strikes between Israel and Iran. The war has left much of Gaza in ruins and has killed over 43,000 Palestinians, mostly women and children, according to local health authorities who do not distinguish between civilians and combatants.

An official with the Palestinian Islamic Jihad Group said the strike in Mazzeh targeted one of their offices, and that several members of the group were killed. The official spoke on condition of anonymity because he wasn’t authorized to speak to the media.

Syria’s state news agency SANA said the country’s air defenses were activated against a “hostile target” south of the central city of Homs.

Tehran has been a main backer of Syrian President Bashar Assad’s government since a 2011 uprising turned into a full-blown civil war and has played an instrumental role in turning the tide of the conflict in his favor.

Iran has sent scores of military advisers and thousands of Iran-backed fighters from around the Middle East to Syria to fight on Assad’s side. Tehran also has been an economic lifeline for Assad, sending fuel and credit lines worth billions of dollars.

Israel has carried out hundreds of airstrikes in Syria targeting members of neighboring Lebanon’s Hezbollah and officials from Iranian-backed groups.

Hezbollah began firing into Israel on Oct. 8, 2023, in solidarity with Hamas in Gaza. Since then, more than 3,200 people have been killed in Lebanon and more than 14,200 wounded, the country’s Health Ministry reported. In Israel, 76 people have been killed, including 31 soldiers.

Lebanon’s state media said an Israeli airstrike Thursday hit a building in Baalbek city in eastern Lebanon, killing at least nine people and wounding five others.

Speaking Thursday, Israeli military spokesman Rear Adm. Daniel Hagari said that over the past week, Israel had “struck more than 300 targets from the air across Lebanon, including about 40 targets in the heart of the Dahiyeh in Beirut.”

Israeli warplanes intensified airstrikes Thursday, targeting various areas in southern and eastern Lebanon, including the outskirts of the southern port city of Tyre and the Nabatieh province, the National News Agency said.

Throughout the day, sporadic airstrikes targeted Beirut’s southern suburbs in an uptick in attacks on the area over the past two days, with the Israeli army issuing evacuation warnings for several locations and buildings in the suburbs.

The Israeli military said it carried out strikes on Hezbollah targets in the Dahiyeh area, including weapons storage facilities and command centers.
