Tehran has brushed off US calls to pull its forces out of Middle East countries, saying that it is the enemy Washington who should go back home. It comes as Iran marks 40 years since the Islamic Revolution.
As the US own forces start to withdraw from Syria, Washington is increasingly worried that Tehran is getting too entrenched in the war-torn country. The US has repeatedly lambasted Iran for its presence in Syria, where Tehran maintains military advisers.
On Monday, the deputy head of Irans Revolutionary Guards fired back at Washington: The enemy cannot ask us to leave the region. They must leave the region.
We will help any Muslim anywhere in the world, Brigadier General Hossein Salami added.
Its not the first time that Iran has rejected US demands to curb its influence. Last week, a senior aide to Supreme Leader Ali Khamenei, Ali Akbar Velayati, warned: Whether they want to or not, the Americans must leave Syria.
