Russia-Ukraine war at a glance: what we know on day 418 of the invasion

A court in Moscow has sentenced the opposition activist Vladimir Kara-Murza to 25 years prison; Slovakia will temporarily halt imports of grains and other selected products from Ukraine

A court in Moscow has sentenced the opposition activist Vladimir Kara-Murza to 25 years prison, in one of the most high-profile cases to date of a Russian dissident being jailed for opposing the invasion of Ukraine. Kara-Murza, a father of three, was detained in April 2022 and charged with spreading false information about the Russian army in Ukraine. He was later also charged with high treason" over a series of public speeches he made that criticised Kremlin policies and the war in Ukraine. Kara-Murza's ruling is the longest sentence yet given to a political opponent of Vladimir Putin, as the Kremlin further steps up its relentless crackdown on dissent.

Russia's lack of commitment to protecting fundamental human rights, including freedom of expression, is alarming," British foreign secretary James Cleverly said in a statement. We continue to urge Russia to adhere to its international obligations including Vladimir Kara-Murza's entitlement to proper healthcare."
