On 10 May, Israel said it had struck almost all of Iran's military infrastructure in Syria following an Iranian attack. After twenty rockets were fired at Israeli positions in the Golan Heights, it responded by launching what a spokesman called ‘one of the broadest aerial operations in recent years’. There was no immediate comment from Iran, whose deployment of troops to Syria to back the government in the country's civil war has alarmed Israel. Iran has repeatedly called for an end to the existence of the Jewish state.
