Russia uses incendiary thermite shells bombing Ukrainian positions overnight as Vladimir Putin “demands firm dates” when his forces will seize Bakhmut.

His forces are bombarding the Ukraine army with MZ-21 thermite shells fired from Grad multiple rocket launchers.

These ignite with a combustion temperature of up to 2,700 degrees Celsius.

Russian state media has highlighted the use of the thermite - or magnesium - ammunition at Bakhmut and apparently elsewhere in Donetsk region.

Footage shows the thermite shell attack that happened overnight, as well as a previous attack from last month.

The weapons were used against Ukrainian firing positions, it was reported.
