THE MARTYRS of Mariupol have vowed to fight to the death in the bloody last stand against Russia in a haunting “final message” as it’s feared the city could fall in HOURS. Major Serhiy Volyna – the commander of Ukrainian forces’ last stronghold at a steelworks in the besieged city – says troops will not surrender despite relentless blasts by Russian fighters.

Major Volyna, of the 36th separate marine brigade, has insisted forces at the plant will “not lay down our weapons” despite being outnumbered ten to one. In a chilling video, he warned it could be their “last message” as Russian troops surround the area and unleash constant barrages of fire. “This is our appeal to the world. This could be our last message,” he said.

Amid the “hellscape”, at least 20,000 people are feared dead. Ukrainian fighters who remain in Mariupol have been offered a fresh ultimatum to surrender despite not a single soldier accepting the offer on Tuesday. ‘SEVERE AS POSSIBLE’ The Russian Defence Ministry said: “Russia’s armed forces, based purely on humanitarian principles, again propose that the fighters of nationalist battalions and foreign mercenaries cease their military operations from 1400 Moscow time on 20th April and lay down arms.” A similar offer had been made on Tuesday but according to the Russian Ministry of Defence not one soldier surrendered. Ukraine’s President Volodymyr Zelensky says “the situation in Mariupol remains as severe as possible”. It comes as up to 20,000 have reportedly been recruited from Syria and Libya after the long-feared “battle for the Donbas” erupted this week. Explosions were heard along the entire front on Monday as Putin launched a major new offensive to seize control of the east.
