Iran wants to boost Syrian President Bashar al-Assad's military by upgrading the country's air-defense system, the Fars news agency reported on May 29. In an interview with the news agency, Iranian General Said Hamzah Kalandari said that although Syria had its air-defense capabilities, the "Syrian brothers" will be supported with equipment and tactical upgrades. The general, who is active in the Defense Ministry, said the aim was to contain Israeli attacks. Along with Russia, Iran is Assad's most important ally. Iran has been expanding its political and military relations in the region since the 1990s.
