The future of the U.S.-Iran agreement—reached last month to reopen the Strait of Hormuz and resume negotiations—now hangs in the balance following renewed attacks between the two sides. Iran warned on July 13, 2026, that it would consider itself no longer bound by the June memorandum of understanding with the United States if Washington fails to uphold its commitments to end hostilities.
Diplomacy Amid Escalation
Despite the breakdown in trust, Iranian Foreign Ministry spokesperson Esmaeil Baghaei stated in a press briefing in Tehran that Iran would continue diplomatic consultations with mediator countries—Qatar, Pakistan, and Oman—to “prevent escalation” with the U.S. He emphasized that the mediators’ role is to sustain efforts aimed at de-escalating tensions, adding that Iran has been in contact with Qatar and Oman “in recent days”—both nations previously targeted by Iranian military rhetoric—as well as Pakistan.
Baghaei also said Iran is seeking to establish a joint mechanism with Oman for managing maritime traffic through the Strait of Hormuz, but that U.S. pressure on Muscat is obstructing progress.
Sharp Rhetoric Over U.S. Senator’s Death
In a highly charged statement, Baghaei labeled late U.S. Senator Lindsey Graham—a prominent advocate of military action against the Islamic Republic—as “malicious.” Graham died suddenly on Sunday, July 12, 2026. “Our people will not mourn the man whose life philosophy was attack and intimidation… His entire being was malicious,” Baghaei said, echoing sentiments aired by several presenters on Iranian state television who openly celebrated Graham’s death.
Casualties Reported in U.S. Airstrikes
At least one person was killed and seven others wounded in a U.S. air strike on a military base in Nain, Isfahan Province in central Iran, according to the province’s deputy governor. This marks the second reported fatality in Iran on July 13. Earlier in the day, Iranian media reported one death and four injuries from a separate U.S. strike on a rural pumping station in Mahshahr.
Iran has urged Washington to honor its obligations under the provisional understanding reached between the two nations—and simultaneously, the Islamic Revolutionary Guard Corps (IRGC) has escalated its warnings regarding the Strait of Hormuz, declaring that normal maritime navigation “will not be restored” unless conditions change.
