Ukraine’s president Zelenskyy has accused Russian forces of using phosphorus bombs in Ukraine.
International law bans use of phosphorus bombs in areas where they may endanger civilians.
In an address to Estonia’s parliament, the Ukrainian president said Moscow was using “terror tactics” against civilians.
He did not provide evidence for his claim about the use of phosphorus munitions.
Ukrainian officials have repeatedly accused Russia of using such bombs, a charge Moscow denies.
Zelenskyy also accused Russia of forcibly deporting Ukrainians and called for further sanctions on Moscow, arguing such measures were the only way to force Putin to agree to a peace deal.
