The briefing for Tuesday, October 6.

Saudi-backed Yemeni government forces launched a large-scale offensive on Monday, dubbed Operation Yemen Dawn, aiming to retake territory from Iran-aligned Houthi rebels. Yemeni military officials said pro-government forces captured the port city of Mokha and "secured" the Bab al-Mandab Strait, a critical Red Sea chokepoint, with the help of Saudi air strikes. However, Reuters and AFP later cited unnamed government and military sources saying forces had only reached the outskirts of Mokha, and the Houthis denied losing control of either the city or the strait, calling the claims "Saudi propaganda."

The offensive followed the collapse of a four-year informal ceasefire in July, when the Houthis declared a maritime embargo against Saudi Arabia and began striking Saudi airports, oil facilities, and Red Sea tankers. In retaliation for the new offensive, the Houthis launched ballistic missiles and drones at Saudi Aramco facilities in Riyadh and Khurais; satellite imagery reviewed by BBC Verify showed smoke rising from both sites. A Saudi-led coalition said its jets provided "round-the-clock" air support and had destroyed 324 "high-value" targets, while Saudi strikes on Sanaa reportedly killed a schoolgirl and a woman, according to Houthi-run media.

The conflict is drawing in regional powers. Turkey and Pakistan held an emergency meeting in Riyadh and agreed to rapidly deploy military forces to Saudi Arabia, invoking the Mecca Joint Defence Agreement, according to Pakistan's foreign ministry. UN Secretary-General António Guterres condemned the Houthi cross-border attacks and voiced deep concern over the escalation. The Houthis warned civilian airlines that most Saudi airspace is no longer safe, calling it "a theatre of operations."

The stakes extend well beyond Yemen's borders. The Houthis' seizure of areas near Bab al-Mandab last month had already contributed to a surge in global oil prices, since Saudi Arabia has relied on the Red Sea route for exports since the Strait of Hormuz became less viable amid separate U.S.-Israel-Iran tensions. A prolonged fight for control of the strait threatens to disrupt global shipping and further strain energy markets, even as both sides dispute who currently holds the ground.

Canada's Parti Québécois is projected to have won enough seats to form a minority government in Quebec's provincial election, marking its return to power for the first time since 2014. Incoming premier Paul St-Pierre Plamondon reaffirmed his pledge to hold another independence referendum, telling supporters Quebec's "national destiny will be achieved one day," while also vowing to be "the premier of everyone in Quebec." The Liberal and Conservative parties both gained seats, largely at the expense of the collapsing Coalition Avenir Québec, which is not projected to win a single seat.

Quebec has held two prior independence referendums, in 1980 and 1995, both of which failed. Polls suggest only about 30% of Quebecers currently support separation. St-Pierre Plamondon has said he wants to hold any new vote only after Donald Trump leaves the U.S. presidency, citing a need for "an informed and serene debate," which would likely push a referendum to 2029 or 2030. It remains unclear how he would secure such a vote, since the PQ fell short of a majority and rival parties whose support he may need oppose independence.

Beyond the referendum question, St-Pierre Plamondon has signaled he intends to clash with Ottawa over immigration policy and the monarchy, including a pledge to defund Quebec's lieutenant-governor's office and redirect the money to homelessness services — a move likely to face legal challenges given the monarchy's constitutional role. Prime Minister Mark Carney congratulated the premier-designate and said he looks forward to working with him, but the result adds a new unity challenge for Carney's government, which may also face a separate referendum question out of Alberta depending on an upcoming vote there.

Kenya's Health Ministry confirmed the country's first Ebola case on Tuesday, involving a Kenyan citizen who had been living in the Democratic Republic of Congo for seven years. The patient fell ill about a month ago, traveled by road to Kampala, Uganda, then flew to Nairobi on Saturday, passing standard airport screening before being taken to Nairobi Hospital by a relative. He died late Monday in an isolation facility originally built during the COVID-19 pandemic, Health Minister Aden Duale said.

Authorities have identified 28 contacts, including family members and health workers, who will be isolated for 21 days, and are tracing 23 additional passengers and four crew members from the same flight. Testing confirmed the patient carried the Bundibugyo strain of Ebola, a rare variant with no approved vaccine or treatment, though several vaccine candidates are in trials. Kenya becomes the fourth country to record a case in the current outbreak, following Uganda — declared Ebola-free in August — and a single case in France.

The case underscores the scale of what the World Health Organization has called the fastest-growing Ebola outbreak in history, centered in DR Congo's Ituri province since May. The WHO has recorded 4,082 deaths out of 8,463 cases, making it the largest outbreak ever recorded in the country where Ebola was first discovered. The medical charity MSF said the virus is now spreading "like a megafire," with North Kivu province accounting for nearly 40% of new cases nationwide since early September, raising concerns that true case numbers may be undercounted due to gaps in surveillance.

The FBI arrested Wanying Zhang, a 34-year-old naturalized U.S. citizen and real estate agent from Irvine, California, at Los Angeles International Airport on Sunday as she prepared to fly to China. Federal prosecutors allege she surveilled the Seattle-area home of Ting-Yu Lai, the son of Taiwanese President Lai Ching-te, and sent photos, videos, and vehicle license plate information to a Chinese government official. She has been charged with acting as an unregistered foreign agent and appeared in federal court Monday; a detention hearing is set for Wednesday.

According to an FBI affidavit, Zhang and another person traveled to Seattle in September 2025 at the direction of Chinese officials and were recorded by a home security camera filming the target's family from a vehicle. Investigators say such surveillance of a senior Taiwanese official's relatives could be used by Beijing to "obtain leverage" over Taiwan's president during a potential conflict. Taiwan's Presidential Office called the case "a classic case of transnational repression" and condemned what it described as efforts to suppress or threaten pro-democracy figures and their families.

The arrest is part of a broader pattern of Justice Department prosecutions targeting alleged covert agents advancing Beijing's interests inside the United States, including cases involving harassment of pro-democracy activists and efforts to cultivate influence with political figures. The Chinese Embassy did not immediately respond to requests for comment. The case lands at a particularly sensitive moment in U.S.-China-Taiwan relations, with Taiwan remaining a central flashpoint in military and diplomatic tensions between Washington and Beijing.

The Pentagon announced Monday it will execute former Army Major Nidal Hasan by firing squad for the 2009 Fort Hood shooting, which killed 13 unarmed soldiers and wounded 32 others. Pentagon spokesperson Sean Parnell said Secretary of War Pete Hegseth recommended the method and President Donald Trump approved it, writing on social media, "Judgement day for Hasan has finally come." It will mark the first U.S. military execution by firing squad since the end of World War Two.

Hasan, an Army psychiatrist, admitted during his 2013 court-martial that he carried out the attack, which took place in a crowded medical building where soldiers were awaiting deployment checkups. He said he believed he was protecting the Taliban and Muslims in Afghanistan, and later apologized for "any mistakes." He is one of four inmates currently on the U.S. military's death row; any military execution requires presidential approval, appellate review, and a final legal judgment before it can proceed.

Firing squad executions remain rare in the U.S. justice system overall. South Carolina carried out the method last year for the first time in 15 years nationally, and only five states — Idaho, Mississippi, Oklahoma, Utah and South Carolina — currently allow it at the state level. The Fort Hood case will be the first time the method has been applied within the military justice system since the 1940s, marking a historic, if narrow, application of capital punishment law that was reinstated by executive order in 1984 after a 1983 appellate ruling found it unconstitutional.

Pennsylvania has recorded more than 1,000 measles cases this year, state health officials said Monday, making it the largest state-level outbreak in the U.S. in more than three decades. The outbreak, which began in April west of Philadelphia, has caused 198 hospitalizations and five deaths. It is the first time a single state has surpassed 1,000 cases since a multiyear New York City outbreak in the early 1990s that infected more than 4,500 people.

The outbreak is part of a broader national surge: the U.S. is experiencing its worst measles year since 1991, with nearly 3,900 reported cases nationwide, according to the CDC. Eight measles-associated deaths have occurred in the past two years alone — more than the combined total from the previous three decades. Other major outbreaks have hit Texas, Utah, and South Carolina, which previously held the record with 997 cases; New York's governor declared a disaster emergency Monday over cases in neighboring states and rural areas, expanding who can administer vaccines.

Health experts attribute the resurgence to declining vaccination rates. The U.S. had eliminated domestic measles transmission in 2000 by maintaining high immunization coverage, but gaps in vaccination in recent years have allowed the highly contagious virus to spread rapidly once reintroduced. The scale of this year's outbreaks suggests the trend is likely to continue without a reversal in vaccination rates.
