At around 10:00 a.m. local time, a gunman opened fire at the Dreierschützengasse secondary school in the city of Graz. The suspect, a 21-year-old former student who did not graduate from the school, is believed by police to have taken his own life in a school bathroom after fatally shooting 10 students and injuring 12 others—one of them critically. The victims were between 14 and 18 years old. The gunman used two legally owned firearms, a rifle and a handgun, and was not known to police prior to the attack. The motive remains under investigation.

Israeli airstrikes targeted eight buildings across four sites in the southern Dahiyeh suburb of Beirut, marking the first strikes near the capital in over a month and the fourth such attack since the U.S.-brokered ceasefire took effect in November 2024. The Israeli Defense Forces (IDF) announced the attacks in advance via X (formerly Twitter), warning residents to prevent civilian casualties. In a statement, the IDF said the strikes targeted underground drone manufacturing facilities allegedly operated by Hizballah with Iranian support. The attacks triggered mass evacuations and heavy traffic congestion in Beirut. A separate strike was also reported in Ain Qana, southern Lebanon. Lebanese officials condemned the airstrikes as clear violations of international agreements, with President Joseph Aoun and Prime Minister Nawaf Salam strongly denouncing the attacks. The IDF, meanwhile, claimed that Hizballah was manufacturing thousands of drones in civilian areas in anticipation of future conflict, having already deployed drones extensively during past clashes with Israel. Hizballah has previously denied these allegations and issued no immediate response. Both sides regularly accuse each other of undermining the ceasefire, originally established following renewed hostilities in October 2023, when Hizballah launched attacks in support of Hamas, prompting a strong Israeli response, including the killing of Hizballah leader Hassan Nasrallah.

Two suspected Islamist militants were killed in Kampala by a Ugandan army counter-terrorism unit as they approached the Munyonyo Martyrs’ Shrine during Martyrs’ Day commemorations. The suspects, affiliated with the Allied Democratic Forces (ADF) rebel group, which has formed an alliance with the Islamic State Central Africa Province (ISCAP), were on a motorcycle near the site when they were intercepted. One, a female suicide bomber carrying powerful explosives, reportedly detonated during the operation, killing both herself and the driver. Authorities have not confirmed whether their intended target was the Munyonyo shrine or the main celebrations in Namugongo, which were attended by President Yoweri Museveni. Martyrs’ Day honors 45 Christians executed between 1885 and 1887 for refusing to abandon their faith.

Ukraine launched a bold and unprecedented drone offensive deep into Russian territory. The strike, codenamed Operation Spiderweb, was planned over eighteen months and represented Ukraine’s most extensive assault on Russian airpower since the beginning of the war. Coordinated by Ukraine’s Security Service (SBU), the operation involved launching drones from covert positions within Russia itself.

The attack targeted five major Russian airbases spread across vast distances from the Ukrainian border: Belaya Air Base in Irkutsk Oblast (Eastern Siberia), Olenya Air Base in Murmansk Oblast (Arctic region), Dyagilevo Air Base in Ryazan Oblast (western Russia), Ivanovo Severny Air Base in Ivanovo Oblast (central Russia), and Ukrainka Air Base in Amur Oblast (Russian Far East). These sites lie between 500 and 8,000 kilometers from Ukraine, underscoring the extraordinary reach of the operation.

A total of 117 first-person view (FPV) drones were deployed, reportedly damaging or destroying 41 Russian military aircraft, including Tu-95MS and Tu-22M3 strategic bombers, as well as A-50 airborne early warning and control planes. Satellite imagery confirmed extensive damage at Belaya and Olenya airbases, where at least 13 aircraft were visibly destroyed or severely damaged. The estimated financial loss exceeds $7 billion, amounting to nearly one-third of Russia’s strategic bomber fleet.

The drones were smuggled into Russian territory hidden inside trucks disguised as mobile wooden cabins. These makeshift mobile launch platforms were positioned close to the targeted airfields, enabling surprise strikes that successfully bypassed Russian air defense systems.

In response, Russian President Vladimir Putin labeled Ukraine's actions as "terrorist attacks" and vowed retaliation. During a phone call with U.S. President Donald Trump, Putin discussed plans for a response, though specific details remain undisclosed. The operation has sparked international discourse on the evolving nature of warfare, highlighting the efficacy of low-cost drones against traditional military assets. U.S. military officials have cited the attack as a “wake-up call.”

At least 12 people were injured after a man armed with a makeshift flamethrower and Molotov cocktails attacked a crowd while shouting “Free Palestine” during a pro-Israeli walk along Pearl Street Mall in Boulder, Colorado. Authorities identified the assailant as 45-year-old Mohamed Sabry Soliman, an Egyptian national who had been living in the U.S. illegally with his family. Some of the victims suffered severe burns, with at least two airlifted to a specialized unit in Denver. The FBI described the violence as a “targeted terror attack,” stating that Soliman had been planning the assault for a year and had expressed a desire to “kill all Zionist people.” The attack comes amid a rise in both antisemitic and Islamophobic violence since the October 7 Hamas attacks and Israel’s ongoing military operations in Gaza. The conflict has escalated tensions and triggered a surge in politically motivated violence worldwide.

Three local tourists—a man, a woman, and a 15-year-old girl—were kidnapped by armed river pirates, while returning from a tour of Monkey Island near Iquitos in the Loreto region of the Peruvian Amazon. Their boat, carrying ten passengers, was intercepted by six masked assailants who robbed all occupants and took three hostages. The kidnappers demanded a ransom of 30,000 soles (about US$8,000) from the victims' families. After the ransom was paid, the hostages were abandoned in a remote jungle area without means of communication or navigation. They were discovered over 18 hours later by a local fisherman who noticed them signaling for help with a white shirt. The victims were found disoriented, wet, and dehydrated but otherwise unharmed. They were transported to the Bellavista Nanay port in Iquitos and received medical attention. Peruvian authorities have identified four suspects linked to the incident, believed to be part of a criminal network specializing in river piracy. In response, the National Police and Navy have intensified patrols in the area to combat the rising threat of piracy along tourist routes in the Amazon.  This event is part of a concerning trend of increasing river piracy in the Peruvian Amazon, which poses significant risks to tourism and local communities. Tour operators and local residents have expressed alarm over the growing insecurity in the region.  (panamericana.pe, 1 June 2025 & newsinfobae.comlarepublica.pe, 1 June 2025 & infobae.com, 3 June 2025)
