As the war enters its 434th day, we take a look at the main developments.

Fighting

• Kremlin spokesperson Dmitry Peskov said the United States government does not have any data on Russian losses in eastern Ukraine and that estimates claiming 20,000 soldiers had been killed in the past five months had been “plucked from thin air”.
