The Syrian government has asked Iran to take over the supervision and payroll of thousands of Shi'ite militiamen fighting alongside Russian and Syrian troops in support of President Bashar al-Assad, according to a government source and a news report.



The pro-opposition Syrian news website Zaman Al Wasel reported that it obtained a Syrian defense ministry document saying the Assad regime has approved a plan to give Iran responsibility for paying foreign fighters – mostly Shi'ites of varying nationalities. Shi'ite fighters mostly are paid in cash from Iran, the Syrian government and coffers of the Lebanese-based, pro-Iranian Hezbollah, according to analysts.



Iran would foot the bill alone in the future, a Syrian official told VOA on the condition of anonymity, confirming the Al Wasel report.



“The number of Shia militia has increased dramatically during the last two months,” the official said. “While a big part of these militia were recruited by Iran, a relatively big part was recruited by the Syrian government directly. We are speaking about more than 50,000 militants from different nationalities. The Syrian government requested that Iran provide for all of the mentioned militias.”



The document from Al Wasel put the number of fighters to be paid at 88,733 — a figure analysts say is exaggerated. They estimate that about 10,000 Iranian combat troops are in Syria fighting alongside thousands of fighters from Lebanon's Tehran-affiliated Shiite militia Hezbollah and assorted Shiite militia made up of renegade Pakistanis, central Asians and other nationalities. Since January 2013, more than 1,000 members of Iran’s elite Quds Force or other elite Islamic Revolutionary Guard Corps (IRGC) units have been killed fighting in Syria.



Tehran says its forces are in Syria to protect the Zeinab Shrine in Damascus, a Shi'ite holy site. But since 2011, Iran has been a major backer of the Syrian regime in its war with rebel groups across the country, at first sending advisers, then forces from the IRGC and expanding far beyond the shrine area.



Iran has long expressed a desire to command a unified army in the region, particularly in Syria, and its growing power in Syria and Iraq is causing unease in Western capitals. In an interview with the Mashregh news agency last August, Mohammad Ali Falaki, an IRGC leader, announced formation of a unified army in Syria which appears to have come to loose fruition.



“It would hardly be abnormal for Iran's IRGC to be controlling yet more Shia jihadists,” said Talha Abdulrazaq, a researcher at the University of Exeter's Strategy and Security Institute.



In the long run, the formation of a unified army in Syria under Tehran supervision appears very practical, analysts say.



“It seems plausible that the Syrian government shift the responsibility for management and organization of the militias, especially where financial burden is concerned,” said Rasool Nafisi, a Middle East affairs expert in Washington.



Asserting its military prowess would help Iran push its political agenda in the region, some analysts believe.



“The bigger and more advanced army you control, the stronger voice you have,” said Daryoush Babak, a Washington-based retired Iranian military adviser.



But unifying Assad supporters under Tehran’s umbrella could worsen sectarian conflict in the region between Shi'ites and Sunni, analysts say.



Iran is looking for any chance to increase its influence and gain an upper hand against Saudi Arabia, its strongest rival in the war of minds and hearts, analysts say. Saudi Arabia and Iran support rival groups in Syria's civil war. And In a speech in Saudi Arabia, President Donald Trump accused Tehran of contributing to instability in the region.



"Tehran and Riyadh … keep contradicting each other to prove whose ideology leads the region," said Nafisi.



While Syria has relied on Iran militarily in the fight against rebels and Islamic State, it’s unlikely to grant Tehran a controlling foothold in the country, analysts say.



“In Syria, it is not likely to happen as long as the Assad regime harbors ambitions of regaining sovereignty rather than being reduced to an Iranian protectorate,” said Alfoneh.
