Severodonetsk nightmare: 800 Ukrainian troops & civilians trapped in Azot Plant

Bitter fighting in Severodonetsk - the last major city not in Russian control in the region of Luhansk. Governor stated Ukraine still in control of Azot plant, where 100s are sheltering from incessant Russian shelling. A Russia-backed separatist group claimed 300-400 Ukrainian fighters also trapped at the Azot plant. Ukraine says about 800 people hiding in the Azot factory, including 200 employees, 600 Severodonetsk residents. Kyiv fears Severodonetsk may be the next Mariupol - Ukrainians spent weeks under siege before surrendering. Russia earlier shelled the Azot plant for hours, a massive blaze broke out after an oil leak.
