Commercial flights between Iran and Afghanistan resumed Wednesday, after a month of suspension, according to the Iranian Fars news agency.

"Today, Mahan Air transported passengers from Mashhad airport to Kabul airport," the agency said.

It is the first trip of its kind between the two countries since the Taliban movement returned to power in Afghanistan on Aug. 15.

Iran's Civil Aviation Authority announced the suspension of flights to Kabul on Aug. 16 for security reasons.

Previously, the company operated two flights a week between Mashhad and Kabul.

Mahan Air, the second largest Iranian airline after the state-owned Iran Air, has been on the blacklist of entities targeted by US sanctions against Iran since 2011.

According to the United Nations High Commissioner for Refugees, the Islamic Republic hosts more than 3.46 million Afghans, the vast majority of whom are refugees, or more than four percent of the country's population.
