Seyyed Razi Mousavi, a key member of the Revolutionary Guards, died in an Israeli strike, Iran says.
A senior Iranian commander was killed in a suspected Israeli strike in Syria. Iranian media say.
Seyyed Razi Mousavi was "an experienced military adviser" to the Islamic Revolutionary Guards Corps, the semi-official Tasnim news agency said.
It says he was killed in an air strike on the Sayyida Zeinab area south-east of Damascus.
Israel has carried out military strikes in Syria for years, against what it says are Iran-linked targets.
The strikes have increased in frequency over the past months following Hamas' attack on 7 October.
