Iran's foreign ministry spokesman said on Monday that Tehran always welcomed dialogue with Saudi Arabia, but he did not confirm nor deny direct talks this month between the arch-rivals.
The two countries severed diplomatic ties in 2016 and have been engaged in several proxy wars in the region as they vie for influence.
A senior Iranian official and two regional sources had told Reuters that Saudi and Iranian officials held discussions in Iraq in a bid to ease tensions as Washington works to revive a 2015 nuclear pact with Tehran and end the Yemen war.
