Russia’s FSB secret service said on Saturday that it had detained a man it suspects of killing a senior general with a car bomb outside Moscow. Russia has accused Kyiv of being behind the blast on Friday, which killed Gen Yaroslav Moskalik. The FSB alleged a Ukrainian agent it named as Ignat Kuzin rigged a Volkswagen Golf in the city of Balashikha with a homemade explosive device from a Ukrainian secret service stash in the Moscow area and that the bomb was then detonated remotely from Ukraine. A video released by the FSB showed a man identified as Kuzin, and what was said to be his arrest taking place on a forest road. Kyiv has not commented on the blast, which bore the hallmarks of previous attacks on military figures and high-profile backers of the Kremlin’s offensive. Donald Trump has said he doubts Vladimir Putin wants to end his war in Ukraine and expressed scepticism that a peace deal can be reached soon. The comments come only a day after Trump said Ukraine and Russia were “very close to a deal”. As William Christou writes, Trump said on Saturday that “there was no reason for Putin to be shooting missiles into civilian areas, cities and towns, over the last few days … It makes me think that maybe he doesn’t want to stop the war, he’s just tapping me along.” Trump and Volodymyr Zelenskyy, the Ukrainian president, sat down for a face-to-face talk in the Vatican basilica to discuss a possible ceasefire. The White House described Trump’s meeting with Zelenskyy as “very productive”, while Zelenskyy said the talk with the US president was symbolic and had the “potential to become historic, if we achieve joint results”. Trump suggested after the meeting that he might put secondary sanctions on Russia and/or ratchet up banking restrictions.
