Iran-US talks in Islamabad: Strait of Hormuz ‘serious disagreement’ amid uneasy ceasefire
3 min readUpdated: Apr 12, 2026 12:28 AM IST
The Strait of Hormuz has emerged as a major sticking point in the ongoing Iran-US ceasefire talks in Islamabad, with negotiations continuing despite “serious disagreements”, Iran’s semi-official Tasnim news agency reported on Saturday.
A third round of talks is expected later tonight, according to Iranian state television, as both sides attempt to bridge gaps after the first round ended without a breakthrough.
Strait of Hormuz at centre of dispute
US and Iranian negotiators held their highest-level talks in decades in Pakistan on Saturday, seeking to stabilise a fragile two-week ceasefire after six weeks of conflict.
The Strait of Hormuz — a key route for about 20% of global oil and LNG shipments — remains central to negotiations. While US President Donald Trump said American forces had begun clearing mines and reopening the waterway, Iran disputed the claim and denied any US naval transit through the strait.
The US military said two warships passed through the strait and preparations for mine-clearing operations were underway. Iranian state media, however, said Tehran had forced a US vessel attempting to cross to turn back.

VP JD Vance, envoys Steve Witkoff and Jared Kushner arrived in Islamabad on April 10. Iran’s delegation — led by Parliament Speaker Mohammad Bagher Qalibaf and FM Abbas Araghchi — is using Tehran’s 10-point plan as the basis for talks. PM Sharif invited both sides to negotiate “a conclusive agreement to settle all disputes.”
✶ FLASHPOINT — LEBANON
Israel’s Offensive Threatens to Unravel the Truce
Israel launched massive airstrikes on Lebanon on the day the ceasefire was announced — killing 303 people on April 8 alone. Netanyahu insists the truce does not cover Lebanon. Iran has warned it may exit the ceasefire if attacks on Hezbollah continue. US-brokered Israel-Lebanon talks are expected in Washington next week.
⚓ HORMUZ STATUS
Strait Still Operating at a Trickle
Despite ceasefire terms requiring Iran to reopen the waterway, only about a dozen ships transited in the first two days. Shipping analysts say 600+ vessels remain stranded, and even at normal pace, clearing the backlog would take over 10 days. Iran says passage requires coordination with its armed forces.

Talks begin amid deep distrust
US Vice President JD Vance, special envoy Steve Witkoff and Jared Kushner met Iranian Parliament Speaker Mohammad Baqer Qalibaf and Foreign Minister Abbas Araghchi for about two hours, according to Pakistani sources.
The meeting came amid rising tensions over competing demands. Iran is seeking:

- Release of frozen assets
- War reparations
- Iranian control or influence over the Strait of Hormuz
- A broader ceasefire, including Lebanon
Washington, meanwhile, is pushing for reopening the strait and restrictions on Iran’s nuclear programme.
Iran has entered negotiations with “deep distrust”, warning it would negotiate “with our finger on the trigger”, government spokesperson Fatemeh Mohajerani said.
Earlier, both delegations also held separate meetings with Pakistani leadership, where Tehran presented its red lines, including reopening the Strait of Hormuz on its terms and compensation for war damage.
Frozen assets dispute adds friction
The talks got off to a tense start following a dispute over frozen Iranian funds. Iranian sources claimed the US agreed to release billions in assets held abroad, but US officials denied the claim.

The competing proposals — Iran’s 10-point plan and Washington’s 15-point framework — underscore the distance between both sides.
Lebanon strikes threaten talks
The negotiations were further complicated by continued Israeli strikes in Lebanon. More than 90 people were reported killed in Israeli airstrikes on Saturday, pushing the death toll in Lebanon to over 2,000.
Iran has insisted that any ceasefire must extend to Lebanon, while the US and Israel maintain that the Hezbollah conflict is separate.
Global markets on edge
The conflict has disrupted global energy supplies, with oil prices surging and shipping traffic through the Strait of Hormuz sharply reduced. Only a handful of vessels have passed through since the ceasefire began.

Despite tensions, three supertankers reportedly transited the strait on Saturday, raising cautious hopes of a gradual reopening.
