Pakistani Army Chief Arrives in Tehran to Mediate US-Iran Talks

Pakistan's army chief traveled to Tehran to revive US-Iran negotiations after talks in Islamabad on April 11 ended without agreement on April 12, despite being the highest-level direct talks since Iran's 1979 revolution. The mediation effort occurs against the backdrop of Pakistan's Strategic Mutual Defence Agreement with Saudi Arabia signed September 17, 2025, which commits both nations to treat aggression against one as aggression against both and has led to Pakistani military deployment to King Abdulaziz airbase in Saudi Arabia's Eastern province. A Pakistan-brokered ceasefire between Washington and Tehran expires April 22, while a US naval blockade of Iranian ports took effect April 14, which Iran's armed forces called piracy. The complex diplomacy involves Saudi Arabia conducting its first public calls with Iranian Foreign Minister Abbas Araghchi on April 9 and April 13, even as Iran continues strikes against Gulf neighbors and Saudi oil infrastructure remains a primary target.
