An attack that killed two US troops in Afghanistan illustrates that the American military is no longer welcome in the country, a senior Iranian adviser has said, adding that US forces will be forced out of Iraq and Syria.

Ali AKbar Velayati, senior adviser to Supreme Leader of the Islamic Revolution Imam Seyyed Ali Khamenei for international affairs, said that without the intervention of invading countries, especially Americans, the process of peace and stability in the country would be accelerated.
