Since the outbreak of the war, Turkiye has weighed its support for Ukraine against maintaining its ties to Russia.

As Vladimir Putin rejects Volodymyr Zelenskyy’s proposal for a face-to-face meeting, the EU is readying penalties.

Zelenskyy will be in Turkiye, but Putin is not on Russia’s team for the first direct Moscow-Kyiv talks since 2022.

Kyiv and European powers have criticised Vladimir Putin for sending a ‘low-level’ delegation to Istanbul.

These are the key events on day 1,172 of Russia’s war on Ukraine.

European leaders have given Russia’s president an ultimatum on agreeing to a 30-day Ukraine ceasefire.

Moscow rejects a US-backed 30-day truce proposal from Ukraine and its European allies, saying no to ‘ultimatums’.

Putin welcomes allies at parade planned to push patriotism and project strength as fighting against Ukraine persists.

Chinese leader, a guest for Moscow’s WWII commemorations, is keen to maintain ‘deep’ relationship with Russia.

Ukraine’s Zelenskyy has not committed to abide by Moscow’s three-day truce, standing by his offer of a 30-day ceasefire.

How has Russia’s leader maintained his longevity – and how has it shaped the world?
