Israel deepens Lebanon incursion, capturing strategic Beaufort castle amid mounting regional tensions

What happened

France 24 Middle East Lebanon reports Israeli troops captured the strategic Beaufort castle mountain near Nabatiyeh in southern Lebanon, planting their flag there on Sunday. This advance represents Israel’s deepest incursion into Lebanon since its withdrawal over a quarter-century ago. The UN Security Council is scheduled to hold an emergency meeting on Monday to address the expanding Israeli offensive.

Outside Brief is treating this as a source-led account. Any disputed responsibility, casualty figure or battlefield claim should be read as unconfirmed/hearsay unless confirmed by another reliable source. The Israeli military describes the target as a key position overlooking Lebanon and northern Israel, recalling that it previously held the fort for 18 years. Israel states its operations focus on the Iranian-backed Hezbollah militant group, known for missile and drone assaults on Israeli positions and northern Israel. Israeli authorities have issued evacuation warnings to Lebanese civilians in southern Lebanon, raising concerns about displacement.

Lebanese Prime Minister Nawaf Salam accused Israel of pursuing a policy of 'total destruction' targeting cities and towns in southern Lebanon. Germany’s Foreign Minister Johann Wadephul expressed serious concern over Israel’s deeper penetration into southern Lebanon, warning that further escalation could lead to increased displacement and exacerbate regional tensions. A Qatari official called the development a 'dangerous escalation.'
