Hamas has been designated a terrorist organization by the U.S., U.K., and the European Union. In a joint statement released Monday, the U.S. along with France, Germany, Italy and the U.K. condemned the group and "its appalling acts of terror" and vowed to support Israel.

Biden reiterated the position in his speech Tuesday.

"In this moment we must be crystal clear: We stand with Israel. We stand with Israel," Biden said. "There is no justification for terrorism. There is no excuse. Hamas does not stand for the Palestinian people's right to dignity and self-determination."

"Hamas offers nothing but terror and bloodshed with no regard to who pays the price," Biden said. "The loss of innocent life is heartbreaking. Like every nation in the world, Israel has the right to respond, indeed the duty to respond, to these vicious attacks."

Defense Secretary Lloyd Austin on Sunday said the U.S. would provide Israel with including munitions. On Monday, National Security Council spokesman John Kirby said the first batch of aid had been dispatched.

"We're surging additional military systems including ammunition and interceptors to replenish ," Biden said Tuesday. "We're going to make sure that Israel does not run out of these critical assets to defend its cities and its citizens."

Biden said the Department of Homeland Security and the FBI are working with state and local law enforcement to identify any domestic threats that could spawn in response to the attacks in the Middle East. He urged Americans to denounce hate.

"This is a moment for the United States to come together to grieve with those who are mourning. Let's be clear: There's no place for hate in America, not against Jews, not against Muslims, not against anybody. What we reject is terrorism."
