Iran Announces Closure of Strait of Hormuz Amid Ceasefire Dispute

Iran has announced the closure of the strategically important Strait of Hormuz, accusing the United States and Israel of violating the terms of a recently agreed ceasefire arrangement.

The announcement was made by Iran’s Khatam al-Anbiya Central Headquarters, the country's top joint military command, which described the move as a response to what it called breaches of the ceasefire agreement, particularly continued military actions in southern Lebanon. Iranian officials warned that the closure represents only the “first step” in a series of possible retaliatory measures if the situation escalates further.

Iran characterized Israeli attacks in Lebanon and U.S. actions in the region as a “betrayal of trust” and claimed that key provisions of the interim peace framework had already been violated.

The Strait of Hormuz is one of the world's most critical energy transit routes, carrying a significant share of global oil and liquefied natural gas shipments. Analysts have warned that any sustained disruption to traffic through the waterway could have major consequences for international energy markets and global shipping.

Despite Iran’s declaration, U.S. Vice President J. D. Vance said he had seen no evidence that shipping traffic through the strait had actually been halted. U.S. officials have likewise indicated that they have not observed military activity consistent with a full blockade.

Meanwhile, a ceasefire agreement between Hezbollah and Israel was reached on Friday, a development viewed as an important step toward easing regional tensions and facilitating broader diplomatic negotiations.

Diplomatic efforts are continuing, with U.S. special envoy Steve Witkoff expected to participate in talks in Switzerland. Iranian negotiators have also reportedly departed for Switzerland to engage in discussions on an interim agreement and the future of the nuclear negotiations.

Commenting on the upcoming talks, Iranian Foreign Ministry spokesman Esmail Baghaei said that the true measure of any agreement would be its implementation, emphasizing that lasting success depends on both sides honoring their commitments.
