The enemy shelled villages near Kupyansk with prohibited weapons

Ukrainian war correspondent Andriy Tsaplienko said this in his Telegram channel.

They are called flechettes. Flechette ammunition is prohibited by international conventions from being used in civilian areas because it is extremely dangerous for civilians. This is considered a war crime," the journalist said.

International conventions prohibit flashbang munitions in civilian areas, as they pose an extreme danger to civilians. The use of this type of weapon is a war crime.

At the same time, military expert Oleh Zhdanov told what types of chemical weapons the Russians possess.

Phosphorus munitions, although called so because of the presence of phosphorus, are actually incendiary, not chemical weapons. In some cases, the use of tear gas has been recorded. Now we are facing a situation in Bakhmut where the substance lewisite is used, which is an extremely toxic substance that has a destructive effect. Once it enters the body, it causes serious poisoning, which leads to irreversible consequences or even death. It is impossible to avoid a lethal outcome without the timely use of an antidote. Russia may also have stockpiles of sarin or mustard gas that were used in Syria," Zhdanov said.

Socportal reported earlier that the Sumy Region had announced evacuation from the border regions.
