"Such claims are unreal," the expert on West Asia affairs said on Wednesday in reaction to allegations raised by a security official in Afghanistan's Farah province on Iran's assistance to the Taliban.

According to FNA, stressing Tehran's constructive role in Afghanistan, he said, "The Islamic Republic of Iran has always pursued the approach of supporting peace and stability in Afghanistan and this well shows the country's strategy of fighting against extremism and violence."

Iranian officials have always underlined full support for the establishment of sustainable peace and security in Afghanistan.

In relevant remarks in September, Iran's Ambassador to the United Nations in New York, Gholam Ali Khoshrou, underlined Tehran's determination to do its best to promote peace and tranquility in neighboring Afghanistan
