Haqqani was quoted as saying by Tolo News that during his visit to Parwan, these soldiers have also been sent to fight in Syria and Iraq in addition to the war in Ukraine.

"I have shared this issue with them (Iranian authorities), Afghans have previously been used in the fighting in Iraq and Syria, and it may have occurred in the war in Ukraine as well," Haqqani said.

Some military analysts told the news portal that Iran makes use of the former Afghan soldiers who have found refuge there as leverage.

"They were forced to contact other groups to provide for their family's costs, not only in Iraq and Syria but also in the Ukraine war, where they were also recruited by the Russians," Sarwar Niazi, a former soldier, told Tolo News.

"The host nations, including Iran, should not use Afghan immigration as a military force," military expert Sadiq Shinwari told the news portal.

The Iranian Embassy in Afghanistan has refuted the claim.

"There may be rumors regarding the use of forces in the war in Ukraine, which the Islamic Republic denies," Sayed Abass Badri, media director of the Iranian embassy in Kabul, told Tolo News.
