DUBAI, April 17 (Reuters) - Significant differences between Iran and the United States remain to reach a deal aimed at ending the war, a senior Iranian official told Reuters on Friday, adding that keeping the Strait of Hormuz open is "conditional on U.S. adherence to the terms of ceasefire".

The official, who spoke on condition of anonymity, said "no agreement has been reached on the details of the nuclear issues," and serious negotiations are required to overcome differences.

BEIRUT, April 17 (Reuters) - Lebanese President Joseph Aoun said on Friday that any future deal reached by the government would not cede any territory or undermine Lebanon's national rights, without saying whether he was referring to prospective talks with Israel.

The televised address was his first speech since the U.S. brokered a ceasefire to end fighting between Israel and armed group Hezbollah on Thursday. The text of the deal says Israel and Lebanon would hold direct talks to produce a "peace between the two countries".

Lebanese President Joseph Aoun said on Friday that his country was on the verge of a "new phase" of "permanent agreements", after the 10-day ceasefire in the Israel-Hezbollah war went into force.

In a speech addressing the Lebanese people and hinting at the Iran-backed Hezbollah militant group the day after US President Donald Trump announced the truce, Aoun said that his country was no longer "an arena for anyone's wars".

Shipping industry figures gave a cautious welcome Friday to Iran's announcement that it was reopening the crucial Strait of Hormuz trade route to commercial freight after nearly seven weeks closed.

Iranian forces' closure of the strait has trapped hundreds of ships in the Gulf and driven up the costs of shipping goods, with captains avoiding the region for fear of attacks or mines.

A spokesman for German transportation giant Hapag-Lloyd, which has ships stuck in the Gulf, told AFP by phone that the reopening was "in general... good news".

TYRE, Lebanon, April 17 (Reuters) - Hassan Abu Khalil's family miraculously survived six weeks of war in southern Lebanon, but tragedy struck in the final minutes before a ceasefire came into force. An Israeli strike late on Thursday killed 13 of his relatives, leaving him the sole survivor.

Abu Khalil, 36, stepped out to see friends just before midnight, when a U.S.-brokered truce between Lebanon and Israel was meant to halt fighting that had raged since March 2 between Israel and armed group Hezbollah.

BOSTON, April 17 (Reuters) - A Tufts University graduate who had been arrested by U.S. immigration agents last year as part of the Trump administration's targeting of pro-Palestinian campus activists has returned to her home in Turkey following a settlement with the government.

Lawyers for Rumeysa Ozturk announced the accord on Friday, a week after President Donald Trump's administration fired an immigration judge who had in January rejected the U.S. Department of Homeland Security's efforts to deport her.

QASMIYEH, Lebanon, April 17 - Lebanese children leaned out of cars flashing victory signs on Friday as they bumped across a makeshift bridge erected overnight across the Litani River after a truce with Israel - but bombed-out ruins and hard times await.

Nearly a quarter of Lebanese have been forced from their homes, both in the south and other Shi'ite Muslim-majority areas, ordered by Israel to leave as it levelled villages and city districts and sent in troops over six weeks of war.

WASHINGTON, April 17 (Reuters) - President Donald Trump told Reuters on Friday that the U.S. will work with Iran to recover its enriched uranium and bring it back to the United States.

"We're going to get it together. We're going to go in with Iran, at a nice leisurely pace, and go down and start excavating with big machinery... We'll bring it back to the United States," Trump said during a phone interview.

He referred to "nuclear dust" and addedthat it would be retrieved "very soon."

France and Britain said Friday they will lead a multinational mission ensure freedom of navigation in the Strait of Hormuz, while emphasising the force would be entirely defensive -- and only deployed once a peace in the region was agreed.

"I can confirm that, along with France, the UK will lead a multinational mission to protect freedom of navigation as soon as conditions allow," British Prime Minister Starmer said after co-chairing a meeting in Paris on the issue alongside French President Emmanuel Macron.

LONDON, April 17 (Reuters) - The threat posed by mines in parts of the Strait of Hormuz is not fully understood and avoidance of the area by ships should be considered, a U.S. navy advisory said on Friday.

"Status of TSS mine threat is not fully understood. Consider avoidance of that area," said the advisory sent by the US navy’s US NCAGS agency to mariners and seen by Reuters.
