Iran's Supreme Leader Ayatollah Ali Khamenei led prayers on December 28 at the funeral of Razi Mousavi, a senior Islamic Revolutionary Guards Corps (IRGC) adviser who was killed in what Iran said was an Israeli air strike in Syria. Khamenei paid tribute "to this martyr's tireless struggle and called for his companionship with the guardians of God," state TV said. His body was flown from Syria to the holy Shi'ite city of Najaf in Iraq before being taken to Tehran. An Israeli military spokesperson declined specific comment about Mousavi's death, but said it took whatever action that was necessary to defend the country.
