Turkish President Recep Tayyip Erdogan has criticized U.S. leader Joe Biden’s remarks describing Russian President Vladimir Putin as a "killer," the state-owned Anadolu news agency reported Friday.  

Biden ignited a diplomatic crisis with Moscow on Wednesday when he answered "I do" after being asked in an ABC News interview if he thinks Putin is a “killer,” adding that the Russian leader would “pay a price” for election meddling.

“Mr. Biden's comment about Putin does not suit a head of state,” Erdogan was quoted as saying after Friday prayers in Istanbul. 

“For me, Mr. Putin has done what is necessary by giving a very, very smart, very classy response,” he added.

On Thursday, Putin mocked Biden’s comments by saying “it takes one to know one” and wishing the 78-year-old “good health.” 

Biden has not minced words for Erdogan, calling him an “autocrat” in a 2019 interview and highlighting Turkey's deteriorating record on human rights. Turkish-U.S. relations are also hampered by Ankara's purchase of advanced S-400 air defense systems from Moscow, which Washington says threaten NATO defenses. 

Erdogan and Putin normally share a close relationship but their bond has been strained over conflicts in Nagorno-Karabakh, Syria and Libya.

Despite their opposing interests, Putin called the Turkish leader “a man of his word who does not wiggle his tail” at his annual press conference in December.
