'Risk level goes up' — Ukraine's strike on Russian bombers could escalate war, US envoy Kellogg says
Ukraine's drone assault on Russia's strategic bomber fleet, known as Operation Spiderweb, could escalate the war and provoke unpredictable responses from Moscow, U.S. Special Envoy for Ukraine Keith Kellogg said in an interview with Fox News on June 3.
The operation, launched by the Security Service of Ukraine (SBU), reportedly targeted four airfields deep inside Russian territory, striking 41 aircraft and inflicting what Kyiv claims is $7 billion in damage.
The targeted air bases reportedly housed Tu-95 and Tu-22M3 bombers, essential carriers of long-range cruise missiles used in Moscow's air strikes on Ukrainian cities.
"I'm telling you the risk levels are going way up," Kellogg said. "When you attack an opponent's part of their national survival system, which is their nuclear triad, that means your risk level goes up because you don't know what the other side's going to do."
According to the SBU, 117 drones were launched from mobile platforms across Russia, enabling simultaneous strikes on targets located thousands of kilometers from Ukraine's borders.
Kellogg also pointed to reports of explosions at the Severomorsk naval base, home to some of Russia's most advanced submarines. Kyiv has not confirmed targeting Russia's Northern Fleet.
"The one that really concerned me was the fact that there have been reports that they attacked the naval, the Northern Fleet headquarters in Severomorsk," Kellogg said. "And if that's the case — when you attack two legs of a triad — it's very clear the risk levels will go up."
Russian officials have denied that the base was hit, and no independent confirmation has emerged.
According to Kellogg, the attacks showed that Kyiv "is not lying down on that."
"Ukraine is basically, 'We can play this game, too.' And they can raise the risk level to levels that are basically, to me, they've got to be unacceptable," he added.

Despite the scale and strategic implications of the Ukrainian operation, Russian President Vladimir Putin has not publicly addressed the strike. U.S. President Donald Trump, who has positioned himself as a would-be peacemaker, has also remained silent.
Pressed by reporters on June 3, White House Press Secretary Karoline Leavitt confirmed that Trump was not informed in advance about the operation.
"I would like to let the president speak on that himself," Leavitt said. She later added, "The president does not want to see this war prolonged. He wants this war to stop."
Ukrainian officials say the operation took 18 months to plan. While Kyiv says the strike dealt a serious blow to Russia's strategic air capabilities, the full extent of the damage remains unverified.
Operation Spiderweb marks one of the most sophisticated and far-reaching Ukrainian operations since the start of the full-scale war in 2022 — and a stark signal of Ukraine's growing capacity to strike deep inside Russian territory.

Ukraine says 'massive' Russian drone attack on Kyiv
Ukraine said Monday "another massive attack" on Kyiv by Russian drones was underway, a day after the country's top military commander vowed to increase the "scale and depth" of strikes on Russia. Diplomatic efforts to end the three-year war have stalled, with the last direct meeting between the two sides almost three weeks ago and no follow-up talks scheduled. "Another massive attack on the capital. Possibly, several waves of enemy drones," said a statement from Tymur Tkachenko, head of Kyiv's military administration. Two people were hospitalised in the Solomianski district, said Kyiv Mayor Vitali Klitschko, and two others were injured near a metro station in the Sviatochinski district, Tkachenko later said. AFP journalists in Kyiv heard the buzzing of a drone flying over the city centre and explosions, as well as gunfire. They saw around 10 people sheltering in the basement of a residential building in central Kyiv waiting for the attack to end, most of them scrolling their phones for news. The latest strikes came after Ukrainian commander-in-chief Oleksandr Syrsky vowed to intensify strikes on Russia. "We will not just sit in defence. Because this brings nothing and eventually leads to the fact that we still retreat, lose people and territories," he told reporters, including AFP. Syrsky said Ukraine would continue its strikes on Russian military targets, which he said had proved "effective". "Of course, we will continue. We will increase the scale and depth," he said. - Fair response - Ukraine has launched retaliatory strikes on Russia throughout the war, targeting energy and military infrastructure sometimes hundreds of kilometres from the front line. Kyiv says the strikes are a fair response to deadly Russian attacks on Ukrainian infrastructure and civilians. At least four people were killed in an overnight Russian strike on an apartment building in the eastern Ukrainian city of Kramatorsk, while a strike on a Ukrainian army training ground later in the day killed three others, officials said. In wide-ranging remarks, Syrsky conceded that Russia had some advantages in drone warfare, particularly in making fibre-optic drones that are tethered and difficult to jam. "Here, unfortunately, they have an advantage in both the number and range of their use," he said. He also claimed that Ukraine still held 90 square kilometres (35 square miles) of territory in Russia's Kursk region, where Kyiv launched an audacious cross-border incursion last August. "These are our pre-emptive actions in response to a possible enemy offensive," he said. Russia said in April that it had gained full control of the Kursk region and denies that Kyiv has a presence there. Russia occupies around a fifth of Ukraine and claims to have annexed four Ukrainian regions as its own since launching its invasion in 2022 -- in addition to Crimea, which it captured in 2014. Kyiv has accused Moscow of deliberately sabotaging a peace deal to prolong its full-scale offensive on the country and to seize more territory. The Russian army said Sunday that it had captured the village of Petrivske in Ukraine's northeast Kharkiv region. Russian forces also sent at least 47 drones and fired three missiles towards Ukraine between late Saturday and early Sunday, the Ukrainian air force said. ant-cad/jxb/tc/fox

Cat café seeks trustee to support Ukrainian orphans
A soon-to-open Blandford cat café is seeking a trustee. The charitable project aims to provide a relaxing space where people can enjoy the company of cats, while also supporting a cause. All profits from the café will be donated to help Ukrainian orphans who have lost their parents in the ongoing conflict. The café, already supported by three trustees, requires one more to officially register as a charity. The funds raised will go directly towards providing the children with essential items such as household goods, clothing and footwear. A spokesperson for the café said: "At present, there are many children in urgent need of material support." The initiative hopes to attract compassionate individuals who are interested in making a tangible difference in the lives of these children. Those interested in becoming a trustee for the project can reach out to Julia Kobzarieva at flittingster@
