Erdogan’s criticism of Biden came after unconfirmed reports by the Washington Post on Monday that the US president’s administration has approved a $735 million arms deal with Israel.

“Today we saw Biden’s signature on weapons sales to Israel,” the Turkish leader said after chairing a cabinet meeting.

“Mr. Biden, you have sided with the Armenians on the so-called Armenian Genocide. Now you are, unfortunately, writing history with blood on your hands in this incident that led to a seriously out-of-proportion attack in Gaza,” he added.

Last month, Erdogan hit out at Biden for his decision to recognize the 1915 Armenian Genocide by the Ottoman Empire.

The Turkish leader’s comments on Monday mark his latest condemnation of the situation in Gaza, which has been bombarded by Israeli airstrikes for a week.

Erdogan branded the Israeli military attacks against the Palestinian enclave a “massacre” and dubbed Israel a “terrorist” country
