The two met on the sidelines of a UN biodiversity summit in Armenia’s capital Yerevan. Pezeshkian rejected allegations that Iran was seeking to develop nuclear weapons, stressing that Tehran remained open to dialogue with Washington to resolve the conflict.

Iran on Friday denied having anything to do with attacks by Yemen's Houthis, a day after Saudi Arabia accused it of having encouraged the group's recent escalation against the kingdom.

Iranian Foreign ministry spokesman Esmaeil Baqaei said in a statement that the Tehran rejects any claim that Iran has played a role in Houthi operations and reiterated Tehran's offer to act as a bridge between the Houthis and Riyadh.
