Yemen’s Iran aligned Houthi forces launched a large scale wave of ballistic missile and drone attacks against southern Saudi Arabia, targeting military, oil and other economic facilities in Abha, Khamis Mushait, Jazan and Najran. The Houthis said they targeted Saudi Aramco facilities in Abha, Najran and Jazan, as well as an air base in Khamis Mushait, in retaliation for recent Saudi airstrikes in Yemen. Saudi authorities said 73 people were wounded, including women and children, while fires broke out at several energy facilities and some operations were temporarily halted. The attacks also caused damage to oil infrastructure, including facilities in Jazan. Saudi authorities described the attacks as a dangerous escalation and said measures would be taken to protect facilities and workers and maintain operations. The Saudi led coalition said it would take necessary measures to deter the Houthis and respond to the attacks.

Police arrested a 48 year old man near the Weisweiler power plant in North Rhine Westphalia over a series of suspected sabotage attacks targeting Germany’s electricity network. He was carrying explosives, and police later found a nearby tent containing additional explosive charges. The suspect is accused of using homemade rockets to fire conductive wires onto high voltage power lines in North Rhine Westphalia, Brandenburg and Saxony, causing short circuits. On 1 September 2026, one attack occurred at the Turnow Preilack substation near the Jänschwalde power plant in Brandenburg, while another targeted the Bergheim substation near Cologne in North Rhine Westphalia later that day. The Bergheim attack shut down several power generation units for several days, although neither incident caused a general power outage. The suspect had left letters claiming responsibility and said the attacks were motivated by opposition to fossil fuels and lignite mining. Authorities believe he may have acted alone and have described the suspected motive as climate extremism.

Authorities in the eastern state of Saxony found and defused nine additional homemade explosive devices near high voltage power lines south of the Graustein substation in the Goerlitz district, bringing the total number of explosive devices discovered in the area to 21. Police and prosecutors said the devices were intended to damage high voltage power lines by causing short circuits. The discoveries followed a series of sabotage incidents targeting Germany’s electricity grid during the previous week. Police were also searching for a 48 year old man who allegedly sent letters claiming responsibility for the attacks and remained at large after apparent explosives were found at his home. Separately, an investigation into a fire at a transformer substation in Berlin determined that the incident was caused by a technical fault. Police in Wesel were also assessing another transformer substation after its security fence was found cut open.

The volcano Anak Krakatau, located in the Sunda Strait between Java and Sumatra, about 150 km/93 miles from Jakarta, began erupting late on 4 September 2026, producing a fountain of lava and booming sounds heard up to 700 kilometers away. On 5 September, schools in the affected area canceled outdoor activities, and fishing trips were called off. Authorities told the public to wear masks and eye protection and to stay indoors after residents reported eye irritation from falling ash. At around 4 a.m. local time on 6 September, a 30-second eruption sent an ash cloud toward Jakarta. The ash reached about 6,000 meters over Java and around 15,000 meters over Sumatra and Banten province. Two further eruptions were recorded later that same day. The ash cloud forced the closure of Soekarno-Hatta International Airport, the country's main airport, causing the cancellation and delay of 209 flights, including international ones. Indonesia's disaster mitigation agency said there was no imminent tsunami risk from the eruption. Volcanic ash remains a serious hazard to aircraft, since it can damage engines and reduce visibility. Anak Krakatau emerged in the 1920s from the caldera left by the 1883 Krakatoa eruption. It has a history of periodic activity, including a 2018 eruption that triggered a tsunami, killing more than 400 people. No casualties or evacuations were reported in this latest eruption.

Vice President Sara Duterte posted P360,000 bail at the Quezon City Hall of Justice on three counts of grave threats against President Ferdinand Marcos Jr., First Lady Liza Araneta Marcos, and former House Speaker Martin Romualdez, a day after Judge Maria Angelica De Ramos issued an arrest warrant. Duterte appeared voluntarily with her lawyers and supporters, saying she feared harassment or worse in police custody and that officers had been harassing, surveilling, and following her since 2023. She underwent booking, including fingerprinting, but submitted her own photos instead of a police mugshot since she wasn't arrested by police, a procedure Quezon City Police District said it had no issue with. The court lifted the arrest warrant once bail requirements were met. Duterte asked media to accompany her inside for safety; police said their presence was only to manage expected crowds, and that they could not confirm her claims of an attempted arrest at her home or through family members.

A Quezon City Regional Trial Court Branch issued a warrant for the arrest of Vice President Sara Duterte over three counts of grave threats after finding probable cause to hold her for trial. The charges stem from an online press briefing in November 2024, during which Duterte allegedly said she had arranged for an assassin to kill President Ferdinand Marcos Jr., First Lady Liza Araneta Marcos and then House Speaker Martin Romualdez if she herself were killed. Duterte has denied that she threatened the three individuals and said she would pursue all available legal remedies. The court set bail at 120,000 pesos for each of the three charges, or 360,000 pesos in total, and rejected her lawyers’ request to defer or recall the arrest warrant. The criminal case will proceed separately from Duterte’s ongoing impeachment trial in the Senate.

Israel claimed to have captured the Ali al Taher ridge above Nabatieh, a roughly 600 meter high position that had served as a Hizballah logistics, command, and tunnel hub. Israeli forces captured the ridge on 2 September but did not take full control of the underground tunnel complex. The operation followed a four phase pattern also observed elsewhere in the Marjayoun corridor: isolation by fire from 28 to 31 August, incendiary and phosphorus munitions to force fighters underground from 29 to 31 August, surface contact from 2 to 3 September, and demolition alongside the announcement from 4 to 5 September. Fatality estimates remain irreconcilable, ranging from Israeli claims of "dozens" killed to reports of 15 Hizballah terrorists killed. Ahead of the eighth round of Rome talks between Israel and Lebanon, Israel announced the release of five Lebanese nationals it had captured, while linking its withdrawal from the ridge to Hizballah's disarmament. Iran separately threatened a large scale response against Israel if its assault on the ridge continued, amid reports that IRGC and Iranian advisers were trapped alongside Hizballah operatives in the underground tunnel network. The capture of the ridge gives the Israeli military control of the high ground above Nabatieh, a major Hizballah stronghold and strategic hub alongside the Amal Movement.
