US-Iran Ceasefire Extension Claims Met with Iranian Denials Amid Ongoing Conflict
REL_TIME: 13 Aug 2026 21:42Z · LANG: EN
Conflicting reports have emerged regarding the status of the US-Iran ceasefire under the Islamabad Memorandum of Understanding (MoU), which is set to expire on August 17, 2026. While Pakistani government sources reported that both nations agreed in principle to extend the 60-day ceasefire, a senior Iranian official strongly denied these claims to Reuters. The Iranian official asserted that no negotiations are underway because the US violated the agreement within 48 hours of its inception. This diplomatic uncertainty occurs against the backdrop of the 'Iran War,' which recently saw direct military exchanges in July, Houthi attacks in the Bab el-Mandeb Strait, and a blockade of the strategic Strait of Hormuz.
// Background
The conflict, referred to as the Iran War, escalated significantly with direct military strikes between the US and Iran in July 2026. Pakistan brokered an initial ceasefire in April, leading to the signing of the Islamabad MoU on June 17, 2026. However, negotiations stalled over security guarantees and freedom of navigation in the Strait of Hormuz. The ongoing blockade has depressed global energy flows, raising Brent Crude to $88.75 per barrel and costing the average American household an estimated $1,000 in fuel and tax increases.
