The spokesperson for the United States Department of State, Matthew Miller, on Monday, claimed that at least nine Americans have been killed in the attack launched by Hamas terrorists on Israel.

Schumer said, “Unfortunately, we know there are Americans who were killed. The Administration told us that they know of four thus far, but, sadly, we know the toll will rise.”

Secretary of State Antony Blinken on Sunday said the US is working overtime to verify reports of missing and dead Americans after Hamas launched an unprecedented attack against Israel.

Blinken, who spoke with CNN’s Dana Bash, said, “We have reports that several Americans were killed. We’re working overtime to verify that. At the same time, there are reports of missing Americans, and there again, we’re working to verify those reports.”

CNN, however, on Monday afternoon reported that the death toll has risen to nine, as Israel ordered a complete siege in Gaza.

Israeli Minister of Strategic Affairs, Ron Dermer told Bash Sunday that Americans are among the scores of hostages being held in Gaza.

The US Embassy in Jerusalem, meanwhile, updated its contingency planning for any potential evacuation by land or air.

The embassy on Saturday issued a shelter-in-place order for its personnel.
