BEIRUT: Israeli missile strikes on Syria killed at least six Iran-backed fighters on Friday, a war monitor said. The dead were all foreign paramilitaries fighting alongside President Bashar al-Assad’s forces, the Syrian Observatory for Human Right said. The missiles, which were fired from Lebanese airspace, hit positions held by Iran-backed militias in the Masyaf district of Hama province, Observatory chief Rami Abdul Rahman said. One also targeted a government-run research centre, where surface-to-surface missiles are developed and stored, the Britain-based watchdog said. Iranian experts are believed to work in the research centre. The Israeli military said it would not comment on reports in foreign media.
