US Central Command claims targets also included boats trying to lay mines, rattling ceasefire, while Iranians meet with Qatari prime minister in Doha

• Israel escalates strikes in Lebanon as Netanyahu vows to ‘crush’ Hezbollah

Welcome to the Guardian’s continuing live coverage of the crisis in the Middle East.

US forces attacked missile sites in southern Iran and boats trying to lay mines on Monday, US Central Command said, as top Iranian negotiators arrived in Doha for talks to end the war.

Trump said the enriched uranium held by Iran could be destroyed inside the country, in a process overseen by an international nuclear agency. Experts said his announcement could amount to a major concession to Tehran.

Trump also said any deal to end the war with Iran should require certain countries in the region – Saudi Arabia, Qatar, Egypt, Jordan, Turkey and Pakistan – to sign up to the Abraham accords. The agreements aimed at normalising relations with Israel were brokered by the US during Trump’s first term.

Israeli prime minister Benjamin Netanyahu vowed to “crush” Hezbollah in Lebanon, dealing another blow to hopes for a US-Iran deal. Tehran has demanded that any peace accord apply to the fighting in Lebanon as well.

Iranian foreign minister Abbas Araghchi praised Hezbollah for the Tehran-backed militant group’s ongoing resistance in Lebanon against Israel.

Iran’s armed forces are ready to deliver an “immediate and decisive response” to any renewed hostile action by its adversaries, Ali Abdollahi, commander of the Khatam al-Anbiya Central Headquarters, was quoted by the Tasnim news agency as having said.

He said Tehran had the upper hand militarily, including in the management of the strait of Hormuz, and would not allow Donald Trump to “create false narratives over the situation on the ground.”
