An Iranian official says Saudi Arabia should not be the one hosting talks on Yemen's conflict since the kingdom is involved in the crisis with Saudi-led airstrikes targeting the country's Shia rebels. Ali Akbar Velayati, an adviser to Iran's supreme leader Ayatollah Ali Khamenei, says a dialogue on Yemen should be mediated by an international organisation and held in a "neutral country." Velayati spoke on Monday during a visit to Beirut.
