Kiev, May 6: Ukraine has accused Russia of attacking the besieged city of Bakhmut with phosphorus munitions, a media report said.
In drone footage released by Ukraine's military, Bakhmut can be seen ablaze as what appears to be white phosphorus rains down on the city, BBC reported.
White phosphorus weapons are not banned, but their use in civilian areas is considered a war crime. They create fast-spreading fires that are very difficult to put out. Russia has been accused of using them before as well.
Russia has been trying to capture Bakhmut for months, despite its questionable strategic value. Western officials have estimated that thousands of Moscow's troops have died in the assault.
