Israel seizes castle in Lebanon as it expands ground offensive
Israeli forces seized the strategic Beaufort Castle in southern Lebanon as part of an expanded ground offensive against Hezbollah, marking one of Israel’s deepest advances into Lebanese territory in more than two decades. The Israeli military said the hilltop fortress and surrounding ridge were being used by Hezbollah to support attacks on northern Israel, while Defence Minister Israel Katz described the operation as part of a broader effort to dismantle the group’s military infrastructure near the border.

11 dead as all bodies recovered after Washington chemical explosion
Authorities in Washington state confirmed that all 11 missing workers have been found dead following a massive explosion and fire at a chemical processing facility earlier this week, bringing the final death toll to 11. Emergency crews spent several days searching through heavily damaged sections of the site after the blast triggered a large-scale industrial fire and forced evacuations in surrounding areas due to concerns over hazardous materials. Investigators are continuing to examine the cause of the explosion, which is already being described as one of the deadliest industrial accidents in the United States in recent years.

US ‘more than capable’ of resuming war against Iran, Hegseth says
U.S. Defense Secretary Pete Hegseth said Washington is “more than capable” of resuming military operations against Iran if ongoing negotiations fail to produce a final agreement, signalling that the U.S. remains prepared for further escalation despite current ceasefire efforts. Speaking at the Shangri-La Dialogue security summit in Singapore, Hegseth said American weapons stockpiles were sufficient both in the Middle East and globally, while stressing that President Donald Trump still prefers a diplomatic resolution to the conflict. His comments came as U.S. and Iranian negotiators continue discussions over extending the ceasefire.
04
Ukrainian drones hit pipeline, refinery, fuel depot in overnight strikes
Ukrainian drones struck multiple energy and fuel infrastructure sites inside Russia overnight, including a pipeline facility, an oil refinery and a fuel storage depot, as Kyiv continued its long-range campaign targeting assets linked to Russia’s war effort. Russian authorities said air defence systems intercepted dozens of drones across several regions, though fires and damage were reported at a number of industrial sites, with emergency crews deployed to contain the incidents.
05
PSG fans riot in Paris and clash with police after Champions League win
Thousands of Paris Saint-Germain supporters flooded the streets of Paris after the club’s UEFA Champions League victory, with celebrations in several areas descending into clashes with police and widespread disorder. French authorities said more than 130 people were arrested after some fans set fires, launched fireworks, damaged property and confronted riot police near locations including the Champs-Élysées and Parc des Princes stadium. While the majority of supporters celebrated peacefully, police deployed tear gas and large security forces to contain unrest.

Israel Takes Famous Crusader Castle, Here's Why It Matters
In today's conflict tracker, we explain why a 12th-century castle is still a prize sought after even by modern militaries.
Basedment Analysis
Conflict Tracker
Hezbollah-Israel Perched on a sheer cliff in the Nabatieh highlands of southern Lebanon, Beaufort Castle (known in Arabic as Qalaat al-Shaqif) has commanded the landscape for nearly nine centuries. The 12th-century Crusader fortress sits on a steep cliff overlooking both southern Lebanon and northern Israel, earning it the description among Lebanese military figures as "an eye on the south." That description isn't just a bit of romantic language, it reflects a hard geographic reality that every army to hold this ridge, from Crusaders to the PLO to the IDF to Hezbollah, has understood immediately: whoever controls Beaufort controls the visual and tactical depth of the entire theatre below… But this view (both literally and figuratively) may have changed since the introduction of FPV drones.
On Sunday, Israeli troops seized the 900-year-old castle and its surrounding ridge, the military's deepest ground advance in Lebanon since it withdrew from exactly this position 26 years ago, coming despite a ceasefire announced more than six weeks prior. According to the IDF, Hezbollah had used the ridge as a launch platform for hundreds of projectiles directed at Israeli civilians and soldiers, making it less a symbol and more an active fire-control position. Israeli Defence Minister Katz announced troops would remain at Beaufort as a permanent fixture of Israel's expanding security zone in southern Lebanon. My biggest takeaway is just how valuable this location will be given Hezbollah’s expanding drone capabilities. If there is one lesson to take away from Ukraine – and there are many lessons – in the age of drone warfare, the more obvious the target, the more drones you can expect your way. I suspect this base will be pestered constantly by FPV drones reducing the overall effectiveness of this famous castle.
The clearest statement of intent, however, came from Netanyahu himself: "I instructed the IDF to expand the maneuver in Lebanon," he said. "Our forces crossed powerful obstacles. They seized commanding terrain and captured the Beaufort Ridge. And now my instruction is to deepen and expand our hold on areas that were under Hezbollah's control. We are initiating action, we are operating on all fronts — in Syria, in Gaza, and in Lebanon. It will take time, but we will complete the mission."
Source for Netanyahu comments For Lebanon, that language carries a weight that goes well beyond any single castle, it is a declaration that Israel's military posture in the country is no longer reactive, and that the April ceasefire, however nominally intact, is not functioning as a boundary on Israeli ambition.

TODAY IN HISTORY (May 31, 1921): The Tulsa race massacre began in Oklahoma as mobs of both African Americans and whites descended on the courthouse where a Black man, who was accused of assaulting a white woman, was being held; in the ensuing violence, Tulsa's prosperous Black neighbourhood of Greenwood was destroyed and as many as 300 people were killed, mostly African Americans.
