Hours before his 8:00 PM ET deadline, US President Donald Trump escalated his rhetoric on Truth Social, posting that "a whole civilization will die tonight, never to be brought back again" if a deal was not reached. He reiterated threats to target Iranian power plants and bridges, drawing immediate condemnation from Amnesty International and international legal scholars who warned that strikes against indispensable civilian infrastructure would constitute violations of the laws of armed conflict.

Prior to the ceasefire announcement, kinetic operations continued inside the Iranian capital. A military strike destroyed part of a synagogue in Tehran along with adjacent residential buildings, according to security officials and media personnel at the scene. The strike occurred as back-channel diplomatic negotiations were reaching a critical phase, intensifying pressure on both sides to reach an agreement before the evening deadline.

Pakistani Prime Minister Shehbaz Sharif and Field Marshal Asim Munir engaged in urgent final-hour diplomatic intervention with both US and Iranian leadership. Sharif publicly requested President Trump to extend the deadline by two weeks, citing "steadily, strongly and powerfully" progressing diplomatic efforts. The Pakistani mediation was backed by a sweeping 10-point peace proposal submitted by Tehran, which served as the substantive framework for the ceasefire terms that followed.

Less than 90 minutes before the US deadline, President Trump announced a two-week "double-sided" ceasefire. The pause is strictly conditional upon the "COMPLETE, IMMEDIATE, and SAFE OPENING" of the Strait of Hormuz. Iran's Supreme National Security Council confirmed the agreement within the hour, with Foreign Minister Seyed Abbas Araghchi stating Iran will coordinate safe passage through the strait. The announcement averted the promised destruction of Iranian power plants and bridges, shifting the conflict into a tense diplomatic phase.

Following the US announcement, the Israeli Prime Minister's Office confirmed to international outlets that Israel will abide by the suspension of strikes. Israeli compliance is conditioned on Iran immediately opening the Strait of Hormuz and ceasing all attacks on the United States, Israel, and other regional countries - effectively pausing Israel's participation in Operation Roaring Lion for the duration of the two-week diplomatic window.

Following the ceasefire announcement and the anticipated unblocking of the Strait of Hormuz - a chokepoint for approximately 20% of the world's oil supply - global financial markets posted a massive relief rally. The BSE Sensex surged over 2,600 points and the Nifty50 opened above 23,800. Heavily inflated global oil and LNG prices began dropping sharply in response to the de-escalation, offering the first significant economic relief since the Hormuz blockade began 40 days earlier.
