Iran's elite Revolutionary Guards Corps moved their wounded fighters from Aleppo University Hospital to an unknown place in the divided city of Aleppo, well-informed sources said Wednesday.
Hezbollah wounded were among the transferees, the source revealed.
Iran has its own medical department in the government-held hospital in western Aleppo city.
The move came days after Syrian resistance broke a month-long siege on Saturday where almost 275,00 people had been trapped in the eastern neighborhoods of Aleppo.
Two leaked records by a Hezbollah militant on the battlefields of Aleppo city claimed that the Lebanese militia fighters were the only ones who kept fighting the Syrian resistance forces in the siege-break battles.
Syrian regime forces have a low morale and most of them fled their bastions with Iranian backed fighters, according to the audio tape.
The criticism for Syrian army droop and decay was not the first. Two years ago Bashar al-Assad's primary adviser, Bouthaina Shaaban, slammed Hezbollah for claims that its forces are the real force fighting Syrian resistance.
Meanwhile, the United Nations called on Tuesday for an urgent ceasefire in Aleppo, where it said two million people lacked access to clean running water, with children most at risk of disease.
Access is needed to deliver food and medical supplies and for technicians to repair electricity networks that drive water pumping stations, which were heavily damaged in attacks on civilian infrastructure last week.
