The Iranian borders are fully secure and there is no trouble at the boundaries, Major General Hossein Salami told reporters in Mashhad on Friday.
The IRGC forces, the Army and the Police have full control over the border areas and are controlling the situation, the commander added.
He finally noted that there were no concerns about the circumstances along the borders.
His comments came hours after the Taliban took control of Herat, Afghanistan’s third-largest city and a strategic provincial capital in the country’s west.
The Taliban fighters have also seized Ghazni as intense fighting rages between the armed fighters and government forces in Kandahar city.
Herat’s fall on Thursday marked the biggest prize yet for the Taliban, who have taken 11 of Afghanistan’s 34 provincial capitals as part of a weeklong blitz, leaving the capital Kabul increasingly isolated.
