LVIV, Ukraine (AP) – Civilians making the dangerous escape from Ukraine’s embattled southern port of Mariupol describe fleeing through street-to-street gun battles and past unburied corpses as a steady Russian bombardment tries to pound the city into submission. While Russian forces carry on with the siege after Ukraine’s leaders defied their demand to surrender, Russian ground offensive in other parts of the country advanced slowly or not at all. It was knocked back by lethal hit-and-run attacks by the Ukrainians. The Ukrainian army said early Tuesday that it had forced Russian troops out of a strategically important Kyiv suburb after a fierce battle.
