Donetsk residents in Ukraine have reportedly sighted multiple showering of white glowing particles, suspected to be the internationally prohibited phosphorous incendiaries, falling on residential quarters.

Residents suspect the particles are incendiary shells stuffed with white phosphorous, akin to the military assault in the eastern city of Slavyansk in June.

The use of Incendiary bombs, designed to start fires using substances, like napalm, thermite, or white phosphorus, has been strictly prohibited by the UN.

Former UK army officer, Charles Shoebridge, said on RT News that the video, "does appear to show some of the characteristics one would expect to see with the use of white phosphorus or a similar incendiary ammunition.

"In particular, a large number of brightly burning particles falling rapidly to the ground, without the assistance of, for example parachutes to slow their descent, suggests this wasn't a more commonly used illumination ammunition, such as flares."

No official reports from Donetsk have confirmed the result of the night shelling or whether the white rain was in fact, white phosphorous.

Despite Moscow's demands for investigations into the use of incendiary bombs in Ukraine, Kiev authorities have repeatedly denied the use of such weapons against civilians.

According to the statistics of the Donetsk People's Republic, at least 839 people have died in attacks from the Ukranian Army over the last three months.
