By Thomas Suen and Louisa Gouliamaki 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.

The halt to weeks of fighting is being celebrated in Lebanon, but it will be difficult to ensure it lasts.

The concerns echo the findings in a report from the Pentagon in early April, which determined that Iran was actively digging out its remaining arsenal of missiles and launchers

The ceasefire appears to have led Iran to reopen the Strait of Hormuz, easing the global energy crisis. But major obstacles remain, as Hezbollah has not formally agreed to the truce and wants Israel to withdraw.

Pakistan’s army chief is set to meet with Iranian officials in Tehran on Thursday in a bid to extend the ceasefire which paused almost seven weeks of war between Israel, the U.S. and Iran that have killed thousands of people and upended global markets by disrupting the flow of oil.

The Trump administration feels “good about prospects of a deal” with Iran, the White House said, noting that a potential second round of talks would likely be held in Pakistan. Follow along for live updates.
