There was no immediate comment from Israel, which has repeatedly said it will not allow arch-enemy Iran to expand its presence in Syria.

Razi Moussavi "was killed during an attack by the Zionist regime a few hours ago in Zeinabiyah district in the suburbs of Damascus," Tehran's official IRNA news agency reported, using a different name for Sayyida Zeinab south of the Syrian capital.

IRNA said Moussavi was "one of the most experienced advisors" of Quds Force, the foreign arm of the Islamic Revolutionary Guard Corps (IRGC).

The general was "active in the field of providing logistical support to the axis of resistance in Syria," IRNA added, referring to groups backed by Tehran and arrayed against Israel.

The IRGC confirmed Moussavi's death in a statement, saying he was killed in a "missile attack".

The statement added that Moussavi was a companion of General Qassem Soleimani, Iran's revered Quds commander who was killed in Baghdad in a US drone strike in 2020.

Next week Iran will mark the fourth anniversary of Soleimani's assassination.

A Britain-based monitor, the Syrian Observatory for Human Rights, reported Israeli strikes Monday on positions used by Iranian groups and by Lebanon's powerful Tehran-aligned Hezbollah in the Sayyida Zeinab area.

Residents of the area reported hearing loud explosions and seeing columns of smoke rising from farms there.

Israel has launched hundreds of air strikes on its northern neighbour since Syria's civil war began in 2011, primarily targeting Iran-backed forces and Hezbollah fighters as well as Syrian army positions.

Israel, which rarely comments on reported strikes in Syria, has intensified attacks there particularly against Hezbollah since the start of its war against Hamas -- also backed by Iran -- triggered by the Palestinian militant group's deadly October 7 attacks.

The Islamic republic, which supports Hamas financially and militarily, has hailed the attacks as a "success" but denied any direct involvement.

According to an AFP tally based on Israeli figures, about 1,140 people, mostly civilians, were killed in Israel on October 7.

Israel's relentless retaliatory military campaign in Gaza has killed more than 20,400 people, mostly women and children, according to the health ministry in the Hamas-run coastal territory.

Iran does not recognise Israel and has made support for the Palestinian cause a centrepiece of its foreign policy since the 1979 Islamic revolution.
