Lviv: Ukrainian officials defiantly rejected a Russian demand that their forces in Mariupol lay down arms and raise white flags Monday in exchange for safe passage out of the besieged strategic port city.
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.
In the capital Kyiv, Russian shelling devastated a shopping center near the city center killing at least eight people.
The encircled southern city of Mariupol on the Sea of Azov has seen some of the worst horrors of the war, under Russian pounding for more than three weeks. Strikes hit an art school sheltering some 400 people only hours before Russia's offer to open two corridors out of the city in return for the capitulation of its defenders, according to Ukrainian officials.
Ukrainian officials rejected the Russian proposal for safe passage out of Mariupol even before Russia's deadline of 5 am Moscow time (0200GMT) for a response came and went.
There can be no talk of any surrender, laying down of arms," Ukrainian Deputy Prime Minister Irina Vereshchuk told the news outlet Ukrainian Pravda.
"We have already informed the Russian side about this. Mariupol Mayor Piotr Andryushchenko also dismissed the offer shortly after it was made, saying in a Facebook post he didn't need to wait until the morning deadline to respond and cursing at the Russians, according to the news agency Interfax Ukraine.
