Ukraine rejects Russian demand for surrender in Mariupol

Ukrainian officials have defiantly rejected a Russian demand that their forces in Mariupol lay down arms and raise white flags in exchange for safe passage

LVIV, Ukraine -- 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.

Russia has been barraging the encircled southern city on the Sea of Azov, hitting an art school sheltering some 400 people only hours before offering to open two corridors out of the city in return for the capitulation of its defenders, according to Ukrainian officials.

Fighting for Mariupol has continued to be intense, even as the Russian offensive in other areas has floundered to the point where Western governments and analysts see the broader conflict grinding into a war of attrition.

Ukrainian officials rejected the Russian proposal for safe passage out of Mariupol even before Moscow's 5 a.m. deadline for a response came and went.
