Russia drops incendiary phosphorous bombs on last Ukrainian stronghold in Mariupol

Ukraine accused Russian forces of dropping phosphorus bombs on Mariupol's Azovstal steel plant on Sunday, as the families of the fighters trapped in the sprawling complex said they fear their fight is coming to an end, Report informs via the Daily Mail.

An aerial video posted to social media on Sunday showed the attack on the plant, where Ukrainian soldiers have been making a final stand against the Russian onslaught on the port city that has been all-but reduced to rubble.

After weeks of Russian siege and bombardment, Mariupol - found in Ukraine's eastern Donbas region - is in Russian hands, but hundreds of Ukrainian fighters are holding out under heavy fire at the steel works.

A number of civilians who were sheltering in the plant were evacuated this month with the help of the International Committee of the Red Cross and the UN.

The footage of the attack begins with an aerial view of the vast Azovstal plant, when suddenly a Russian missile detonates in mid-air - releasing a fiery burst over the already heavily damaged factory buildings below.
