"Yeah, we're very concerned," Kirby said on Thursday regarding Iranian threats of retaliation against Israel. "In fact, one of the things that the [Israeli] prime minister and the President [Joe Biden] talked about today was this very public, very real threat by Iran to the state of Israel."
Biden has publicly expressed anger over Israel's recent attack on a convoy of World Central Kitchen volunteers that killed seven, although the White House has clarified they will continue providing the ally with lethal aid. The death toll of Palestinians in Gaza stands at some 33,494 as Israel has continued its military operation in the enclave after a surprise attack by Hamas on October 7 last year.
