April 26 (UPI) -- Iran's foreign minister conveyed Tehran's red lines to the United States through Pakistani mediators Sunday during a brief visit to Islamabad en route to Russia, where he is expected to meet with President Vladimir Putin.
It was Foreign Minister Seyed Abbas Araghchi's second visit to Pakistan in 48 hours. He is on a three-country trip to Pakistan, Oman and Russia that began Friday amid stalled peace talks between the United States and Iran.
Araghchi arrived at Nur Khan Air Base on Sunday afternoon and was met by Pakistan's Interior Minister Mohsin Naqvi and Iranian Ambassador to Islamabad Reza Amiri Moghadam, according to the state-run Islamic Republic News Agency.
During the brief visit, Araghchi transmitted written messages to the United States through Pakistan outlining "certain red lines of the Islamic Republic of Iran, including nuclear issues and the Strait of Hormuz," the Islamic Revolutionary Guard Corps-linked Fars News Agency reported.
Few details of the messages were made public. Fars reported the messages "were not related" to U.S.-Iran negotiations but were intended "to clarify the regional situation and explicitly state the Islamic Republic's red lines."
