Israel seizes strategic castle in deepest incursion into Lebanon in 26 years

Experts say capture is largely symbolic, but it complicates efforts to extend the ceasefire between US and Iran

Israeli troops have captured a clifftop castle as they made their deepest incursion into Lebanon in more than 26 years, further shattering a nominal US-brokered ceasefire and complicating efforts to extend the separate truce between the Washington and Tehran.

After days of intense fighting and airstrikes in nearby villages, the Israeli defence minister, Israel Katz, said the military had captured Beaufort Castle, also known as Qalaat al-Shaqif, which it had used as a base during its previous occupation of southern Lebanon between 1982 and 2000.
