Iran’s Revolutionary Guards said ships should avoid the main navigation zone and instead follow designated entry and exit paths to reduce the risk of collision with naval mines.

“All ships intending to transit the Strait of Hormuz are hereby notified they should take alternative routes for traffic,” the statement said, emphasizing maritime safety concerns.

The announcement follows Tehran’s agreement to temporarily reopen the strategic strait as part of a two-week truce reached with Washington. The ceasefire was agreed late Tuesday, shortly before a deadline set by U.S. President Donald Trump for Iran to comply with demands related to the reopening of the passage.

The Strait of Hormuz is a critical global energy corridor, through which roughly one-fifth of the world’s oil supply typically passes.

Iran had effectively restricted traffic through the route since early March, contributing to a surge in global energy prices and heightening concerns over supply disruptions.

The designation of alternative routes signals continued operational risks in the waterway despite the ceasefire, underlining the fragile security environment and the potential for further disruption to global shipping and energy markets.

Lebanon’s foreign ministry said it had declared Iranian envoy Mohammad Reza Sheibani persona non grata and instructed him to depart Lebanese territory within days.

The decision was conveyed after the ministry summoned Iran’s chargé d’affaires in Beirut.In a statement, the ministry said the move followed what it described as Tehran’s breach of established diplomatic practices, without providing further operational details.

Lebanon also summoned its own ambassador to Iran for consultations, signalling a sharp deterioration in bilateral relations.The move comes after Beirut accused Iran’s Revolutionary Guards of directing Hezbollah’s military operations in its ongoing conflict with Israel, an allegation that has heightened political and security tensions within Lebanon.

The expulsion unfolds against the backdrop of escalating hostilities between Israel and Hezbollah, now in their fourth week, which have drawn in broader regional actors.

The conflict has triggered widespread destruction in parts of Lebanon and intensified scrutiny of Iran’s role in supporting Hezbollah, a powerful armed group and political actor in the country.

The diplomatic rupture underscores mounting pressure on Lebanon’s government as it navigates internal divisions and external influences during a rapidly widening Middle East conflict.
