US president Donald Trump on Monday at the White House told reporters that the ⁠United States will help Russia after a laboratory worker died at a plague research institute in Siberia.

Trump told reporters as he left the White House for a trip to Nebraska that the outbreak is a “big problem for Russia.”

A laboratory worker at ​a ⁠plague research institute in Siberia ‌fell ill and died in undisclosed circumstances, prompting authorities to quarantine dozens ‌of people.

The death has sparked public health fears on social media, but Russian authorities said on Monday the situation was under control.

“Well, I hate to see them having it,” Trump said. “It’s a rough disease.”He said the US would do what it could to help Russia.

Trump has said he considers Russian president Vladimir Putin someone whom he can work with despite tensions over Russia’s war against Ukraine. “We’ll help,” Trump said. “Anybody who has that kind of a problem, we’ll always help.”

Ukrainian drones have targeted a major oil facility in Moscow Oblast, in what Russian state media described as the largest attack on the region in two years.

A fire was reported at the Volodarsk Linear Production and Dispatch Center, near the village of Konstantinovo.

At least 650 Ukrainian drones were fired towards the capital during the overnight attack, with Russian air defence system downing 105, said Moscow mayor Sergei Sobyanin. Ukraine has yet to comment.

Ukraine says its long-range strikes have neutralised more than half of Russia’s oil refining capacity, hampering Moscow’s ability to supply its forces during its four-and-a-half-year-old invasion.

The defence ministry said late on Sunday that recent strikes on refineries in cities, including Moscow, Yaroslavl, Ust-Luga, Perm, Saratov and Syzran, had disabled 51 per cent of Russia’s oil refining capacity. The claim could not be independently verified.

Moscow and Kyiv have intensified th3eir aerial assaults as progress along the 1,200km front line has largely ground to a halt.

A Ukrainian drone attack killed one person and injured another six in the Moscow region surrounding the Russian capital, governor Andrei Vorobyov said on Telegram on Tuesday.

Moscow mayor Sergei Sobyanin ‌said earlier ‌that Russia downed most of ⁠the 650 drones launched towards the capital overnight, of which 105 ‌drones were ​downed ‌close to ⁠the city ⁠itself.

Ukraine has shifted to using AI-enabled robot guns to intercept and take down Russian drones, said the country’s air force on Monday.

“Robotic turrets are now being installed on bridges” to respond to Russia’s newer jet-powered drones, said air force spokesperson Yuri Ignat.

“There have already been shoot-downs” of the drones, he said, including Russia’s bigger and faster model.

The technology uses “optical vision and artificial intelligence to eliminate the human factor and deliver strikes,” Ignat told AFP.

On 1 January, the next United Nations secretary-general will take over an aging organisation still controlled by World War II powers. What will the world need from that person?

Ukraine has sent 650 drones towards the Moscow region overnight, Sergei Sobyanin, mayor of the Russian capital city, said on Telegram on Tuesday, adding that 105 drones were downed close to the city.

Speaking at the Munich Security Conference in Delhi, Mr Jaishankar said India had held talks with both Moscow and Kyiv in recent months, discussing proposals ranging from protecting Black Sea shipping to halting attacks on energy infrastructure.

Prime minister Narendra Modi urged Mr Putin to end the war as recently as August, when they met on the sidelines of the Shanghai Cooperation Organisation summit in Kyrgyzstan.

Mr Jaishankar said India was now engaged in conversations with Russia as well as Ukraine about practical steps towards reducing hostilities.
