The United States said Tuesday it has "credible information" that Russia may use "chemical agents" in its offensive to take the besieged Ukrainian city of Mariupol, reigniting concerns about the use of such prohibited weapons, AFP reported.
While the West and Kyiv have been warning Moscow since the start of its invasion on February 24 against any use of chemical weapons, fears have grown this week after unconfirmed reports emerged that such weapons may have already been deployed.
