"Signals, which are being sent through deliveries of munitions containing depleted uranium, pose a threat not only to Russia and Turkiye but to all of humanity. The entire humanity should oppose it," Ince said.
"I think Britons should act more carefully on the matter," he added.
In March, UK Minister of State for Defense Annabel Goldie said that the country would provide Ukraine with depleted uranium tank ammunition, including armor-piercing shells for the 14 Challenger 2 battle tanks UK is planning to supply to Ukraine. The Kremlin has repeatedly warned against further escalation of the situation.
Presidential and parliamentary elections are scheduled to be held in Turkiye on May 14. Kemal Kilicdaroglu, put forward by a six-party opposition alliance, is considered incumbent President Recep Tayyip Erdogan's main opponent. The list of presidential candidates also includes Ince and Sinan Ogan of the ATA Alliance.
