Saudi Arabia cut diplomatic ties with Iran last month after protesters outraged over the kingdom's execution of a prominent Shiite cleric set fire to the Saudi Embassy and another diplomatic mission.
Foreign Minister Adel al-Jubeir said the Swiss would facilitate procedures for Iranian Muslims to visit Saudi Arabia for religious pilgrimages. He spoke during a visit by his Swiss counterpart, Didier Burkhalter.
The Swiss Embassy in Tehran already provides consular services to US citizens in Iran in the absence of an American diplomatic mission there.
