Tayyip Erdogan criticised Western powers for their lack of response to the violence between Israel and Palestinians, singling out Austria and the United States, which he said was "writing history with bloody hands," Eurasia Diary reports citing Gulf Today.
"You are writing history with your bloody hands in this incident that is a serious disproportionate attack on Gaza, which is leading to the martyrdom of hundreds of thousands of people," he said.
"You forced me to say this."
Biden's administration approved on Monday the potential sale of $735 million in precision-guided weapons to Israel, according to congressional sources.
Erdogan later turned to Europe, condemning Austria for flying an Israeli flag over the federal chancellery in Vienna on Friday.
"The state of Austria is trying to make Muslims pay the price for the Jews it subjected to genocide," Erdogan said.
Austrian Chancellor Sebastian Kurz, who is firmly pro-Israel, had called the move a mark of solidarity amid the clashes.
