Tensions between the United States and Iran escalated further on Tuesday as Washington announced a blockade of Iranian ports, Tehran warned of retaliatory strikes across the region, and Pakistan stepped up diplomatic efforts to bring both sides back to the negotiating table.
Although a ceasefire reached last week largely held, the situation around the Strait of Hormuz remained volatile, raising fears of renewed conflict and broader economic disruption.
Efforts to reach a lasting agreement in talks over the weekend failed to yield a breakthrough. However, Pakistan has proposed hosting another round of negotiations soon, with officials from both sides indicating that discussions are ongoing and could resume as early as Thursday, though details are yet to be finalised.
Now in its seventh week, the conflict—triggered by US and Israeli strikes on Iran on February 28—has already had a severe impact on global markets. Disruptions to shipping routes and continued airstrikes have damaged key infrastructure across the region, reports AP.
The war has claimed thousands of lives, including around 3,000 in Iran, over 2,000 in Lebanon, and smaller numbers in Israel and Gulf countries. Thirteen US service members have also been killed.
The US military said the blockade, which took effect Monday, applies to vessels traveling to and from Iranian ports. The move could further restrict maritime traffic through the Strait of Hormuz, where Iran has already limited access, allowing only select vessels to pass.
Early indications suggested hesitation among shipping operators, with at least two oil tankers reversing course shortly after the blockade was enforced.
The disruption in the strait—through which about one-fifth of the world’s oil supply normally passes—has driven up global oil prices, increasing the cost of fuel and essential goods worldwide.
Washington says the blockade is aimed at curbing Iran’s oil exports, which have continued despite sanctions, often through covert shipping operations that help sustain its economy.
US President Donald Trump described Iran’s control over the strait as “blackmail,” warning that any vessels approaching the blockade could face immediate military action. Iran, in turn, warned it would strike ports in the Persian Gulf if attacked, with senior officials vowing retaliation.
Meanwhile, diplomatic activity continued on other fronts, with Israel and Lebanon set to begin direct talks in Washington—the first in decades. The discussions are expected to focus on preliminary issues, including ceasefire prospects and security concerns.
Israel has continued its military operations in Lebanon despite the Iran ceasefire, although it has paused strikes in Beirut following international backlash over civilian casualties.
Lebanon is seeking a ceasefire, while Israel has emphasised disarming Hezbollah and exploring a broader peace arrangement, though no commitments have been made to halt military operations.
The developments highlight the fragile and complex nature of the conflict, with military escalation and diplomatic efforts unfolding simultaneously across the region.
