"The missile production plants in Syria have been built by Iran and the missiles designed by Iran are being produced there," Hajizadeh said in an interview on Tuesday.
He also said that even the resistance front in Palestine and Lebanon has received missile-production trainings from Iran.
"The Lebanese Hezbollah and the Palestinian resistance have grown highly powerful in this field (missile production) now," Hajizadeh said.
A senior official of the IRGC announced in September that Iran was standing among the world's top missile powers.
"Today, the Islamic Iran has grown into the world's sixth missile power and this is a major source of pride for the Revolution," Deputy Head of the IRGC Officer Training College Brigadier General Nourollah Nourollahi said in the Northern province of Semnan.
