Israeli forces said they captured Beaufort Castle in southern Lebanon on May 31, 2026, marking what the supplied reporting described as their deepest push into Lebanese territory in more than two decades and a major escalation in a campaign that was already straining a fragile ceasefire.

The two sources in the packet, AFP via Deutsche Welle and BBC News, agree on the central development: Israeli troops seized the medieval fortress overlooking the Litani valley as the military expanded operations against Hezbollah. The site carries military and symbolic weight. BBC notes that the castle sits on high ground long associated with control of the surrounding area, while also highlighting its long history in earlier regional wars.

Israeli leaders presented the move as a turning point. BBC reported that Prime Minister Benjamin Netanyahu called the capture a decisive shift in policy, and Defense Minister Israel Katz linked it to the protection of Israeli communities across the border. The same report said the army described the operation as involving a significant ground force and signaled that it was extending into additional areas.

The seizure of Beaufort Castle was not an isolated maneuver. The packet places it alongside broader evacuation warnings and continued strikes in southern Lebanon. According to BBC, Israel again ordered residents to leave the entire area south of the Zahrani River, warning that anyone near Hezbollah personnel or military assets was in danger. The report says that order covered a large swath of territory and reinforced the impression that troops were moving beyond the earlier Litani line.

European governments reacted sharply. BBC says officials in the United Kingdom, France and Germany criticized the escalation, with French leaders calling for the weapons to fall silent and German officials warning that a deeper Israeli advance could trigger more displacement. Lebanon’s Prime Minister Nawaf Salam, according to the same source, accused Israel of collective punishment in the south.

AFP via DW adds that the castle’s capture was the deepest Israeli advance in more than 25 years and frames it as a major development in the current Israel-Hezbollah war. That source also ties the latest phase of fighting to Netanyahu’s order to expand military operations despite the ceasefire’s already shaky status.

The supplied evidence also shows how unstable the truce had become. BBC reports that both Israel and Hezbollah were accusing each other of violating the arrangement, even as another round of negotiations between Israeli and Lebanese delegations was due in Washington. Against that backdrop, the capture of Beaufort Castle stood out as both a battlefield gain for Israel and another sign that diplomacy was losing ground to military action.
