The United States has delivered a 15-point ceasefire proposal to Iran through intermediaries in Pakistan, according to officials in Islamabad, even as Washington moves additional troops into the Middle East.

The proposal reportedly includes provisions on sanctions relief, civilian nuclear cooperation, limits on Iran’s nuclear and missile programs, monitoring by the International Atomic Energy Agency, and guarantees for shipping through the Strait of Hormuz.

Despite the diplomatic effort, Iran’s military dismissed the initiative and continued its offensive operations. On Wednesday, Iranian strikes targeted Israel and several Gulf locations, including an attack that caused a major fire at Kuwait International Airport, sending thick smoke into the air.

Iran’s actions—particularly its disruption of shipping through the Strait of Hormuz—have driven global oil prices sharply higher and fueled concerns about a wider energy crisis.

At the same time, the United States is reinforcing its military presence in the region. Officials said at least 1,000 troops from the 82nd Airborne Division are expected to deploy in the coming days. The Pentagon is also sending additional Marine units, adding roughly 5,000 Marines and supporting naval personnel.

President Donald Trump has said negotiations are underway, though he has not specified the channels involved. Iranian officials, including representatives of the Khatam al-Anbiya Central Headquarters, have denied that direct talks are taking place.

The parallel tracks of diplomacy and military escalation highlight the uncertainty surrounding efforts to end the conflict as it continues to expand across the region.
