A Vatican delegation is meeting with officials in Iran this week to discuss ways of strengthening interfaith ties.
The visit, led by Cardinal Jean-Louis Tauran, is part of an ongoing attempt by the Vatican to reach out to the largely Muslim Islamic Republic.
Pope Benedict met last year with a delegation of Catholic bishops from Iran and said he wanted to improve relations with the Islamic Republic.
Tauran met with Iranian President Mahmoud Ahmadinejad on Tuesday.
Vatican delegation members will also visit the city of Qom, a Shi'ite spiritual center in Iran, before wrapping up their trip Wednesday.
