High-level negotiations between Iran and the US in Pakistan's capital Islamabad did not result in an agreement due to US demands. The talks took place during a fragile ceasefire period following the 40-day US-Israel war that began in February. Iran emphasized that its nuclear program is peaceful and compliant with international law, while the US side demanded a firm commitment that Iran would not develop nuclear weapons. The Iranian delegation stated that the US's excessive demands and lack of trust were effective in the failure of the negotiations. US President Donald Trump announced military measures in the Strait of Hormuz following the failure of the talks. Trump stated that the US Navy would block Iranian-affiliated ships in the strategic waterway and that strong measures would be taken against threats in the region. Iran, on the other hand, stated that control of the Strait of Hormuz is in its hands and that ship passages in the region occur in coordination with Iran. These developments indicate that tensions in the region continue.
