Even as Russia intensified its attempt to bombard Mariupol into surrender, its offensive in other parts of Ukraine has floundered. Western governments and analysts see the broader conflict grinding into a war of attrition, with Russia continuing to barrage cities.

Ukraine ignores Russia's demand it gives up the city of Mariupol by 05:00 Moscow time, saying there is "no question of any surrender".



Russia had offered to give civilians and fighters safe passage out of the city as long as they gave up their weapons.



But Ukraine's government said Russia could not be trusted, pointing to attacks on civilians during previous evacuation attempts.



Ukraine's president has accused Russia of war crimes in Mariupol, where heavy fighting has now reached the city centre.



An estimated 90% of the city's buildings have been damaged or destroyed.



About 300,000 people remain trapped without power or water, and little food.

In the capital Kyiv, Russian shelling devastated a shopping center near the city center, killing at least eight people and leaving a sea of rubble amid scarred high-rises. Ukrainian authorities also said Russia shelled a chemical plant in northeastern Ukraine, causing an ammonia leak, and hit a military training base in the west with cruise missiles.
