Iran's central military command has said it has closed the Strait of Hormuz again, accusing the United States of continuing its naval blockade of ships sailing to and from Iran's port.

President Trump and Iranian officials have said the Strait of Hormuz is open to all commercial vessels, although shipping firms say they're remaining cautious. Iran's foreign minister, Abbas Araghchi, said the vital waterway would be navigable while the Lebanon ceasefire was in place, warning ships to use designated safe lanes. But Tehran warned it may retract this if Mr Trump continued with his threat to maintain a US blockade on Iranian ports until a comprehensive peace deal is reached. The price of oil has dropped on the announcement.

Iran's foreign minister says the Strait of Hormuz is "completely open" to commercial ships as long as the ceasefire remains in place.
But the US president Donald Trump said the US blockade of the strait will continue until a deal is made.
The announcement comes as European leaders came together to promote a unified message that the strait must be opened without tolls and without restrictions.

President Trump has announced that there will be a ceasefire in Lebanon where Israel has been engaged in a war with Hezbollah. The US leader said both countries had agreed that a ten day pause in fighting would begin at midnight local time. Mr Trump also said he'd be inviting the Israeli prime minister, Benjamin Netanyahu and the Lebanese president, Joseph Aoun to the White House for talks.

Iranians tell the BBC's chief international correspondent, Lyse Doucet, they're unsure the ceasefire will hold. Meanwhile, US Defence Secretary Pete Hegseth has warned Iran to choose wisely in negotiations with the United States. He said the US military was reloading and ready to go at the push of a button. We have a report from inside Tehran and ask about the prospects for talks between Lebanon and Israel.
