An attack on Mariupol, a city of half a million people and potentially a gateway to Crimea, which Russia annexed last March, would almost certainly kill off the cease-fire that aimed to end the 10-month-old conflict.
Shambulio dhidi ya Mariupol, jiji la watu nusu milioni na ambalo linaweza kuwa lango la kuingia Crimea, ambalo Urusi ililiteka mwezi Machi mwaka jana, bila shaka lingeua usitishaji mapigano uliolenga kumaliza mzozo huo uliodumu kwa miezi 10.
