Iran has reimposed restrictions on the Strait of Hormuz, reversing its earlier decision to reopen the vital shipping lane after the United States said it would maintain its blockade of Iranian-linked ports. Tehran stated that control of the strait had returned to strict military oversight and warned that transit would remain blocked as long as the American blockade continued.

The move came despite earlier signs of limited maritime traffic resuming through the waterway, where roughly one-fifth of the world's oil supply passes. Oil prices had briefly eased on hopes of a breakthrough, but renewed restrictions threaten to tighten global energy supplies again.

Tensions remain high ahead of a looming ceasefire deadline in the broader conflict involving Iran, Israel and the United States. While mediators have expressed cautious optimism about a potential agreement, disagreements over the blockade, Iran's nuclear program and the role of armed groups in Lebanon continue to complicate efforts to secure a lasting truce.
