About 5,000 Hizbullah and Hamas fighters have been deployed to quell the anti-government protests, the sources said. They said Hizbullah and Hamas operatives, waving truncheons, were heard shouting in Arabic as they rushed groups of demonstrators.
Both Hamas and Hizbullah were said to have a permanent presence in Iran. The sources said IRGC has been training more than 500 Hamas and Hizbullah operatives a year and often pulled them out of courses to help in internal security.
IRGC was also said to have used Hizbullah tactics against the government of Lebanese Prime Minister Fuad Siniora in 2008. At the time, Hizbullah employed groups of armed fighters in motorcycles to overrun political parties aligned with the pro-Western coalition of Siniora.
