Ukrainian President Volodymyr Zelenskiy said in his daily video address late on Monday that Russia forces could use chemical weapons in Ukraine, but he did not say that chemical weapons have been already used.
There were unconfirmed reports on Monday suggesting that chemical weapons were used in the besieged southern Ukrainian port of Mariupol.
