At least 9 American citizens killed in Hamas attack on Israel: US

The deceased from the deadly attack launched on Israel by Hamas, included at least nine US citizens, US national security council spokesperson said, CNN reported on Monday.

"At this time, we can confirm the death of nine US citizens. We extend our deepest condolences to the victims and to the families of all those affected, and wish those injured a speedy recovery. We continue to monitor the situation closely and remain in touch with our Israeli partners, particularly the local authorities," the spokesperson said in a statement.

He added, "We continue to monitor the situation closely and remain in touch with our Israeli partners, particularly the local authorities."

US authorities have been scrambling to establish how many Americans have been killed or taken hostage in the conflict.

Secretary of State Antony Blinken told CNN on 'State of the Union' Sunday that the US was "working overtime" to verify reports of missing and dead Americans, and Israeli Minister of Strategic Affairs Ron Dermer said Americans are among the "scores" of hostages being held in Gaza, CNN reported.

State department spokesman Matt Miller told CNN on Monday that US authorities are in close contact with Israel's government and the families of those affected by the attack.

The US has pledged to provide additional military support in the coming days, though domestic political dysfunction could hamper the response.

Secretary of Defence Lloyd Austin announced on Sunday stated that he has ordered the US Navy's Ford carrier strike group to the eastern Mediterranean, near Israel.

The USS Gerald Ford is the Navy's most advanced aircraft carrier and it is being deployed to the area, along with a guided missile cruiser and four destroyers, as a deterrence measure, CNN reported.

But the current commander of the US Navy's 5th fleet, which is responsible for US naval operations in the Middle East region including the Red Sea and Gulf of Oman, is still awaiting promotion to deputy commander of US Central Command, which oversees US forces and operations in the region following a hold by Republican Sen.

Meanwhile, as the Biden administration looks to provide additional assistance to Israel, officials were unsure over the weekend about what could be accomplished without a sitting speaker.

Acting Speaker Patrick McHenry has little power outside of recessing, adjourning or recognizing speaker nominations, and it's unclear whether he can participate in intelligence briefings on the crisis, according to CNN.

It further reported citing administrative officials said they will look to the current $100 million in Presidential Drawdown Authority, which allows the rapid dispatch of weapons from existing stocks, to send more aid immediately, according to a person familiar with the discussion.

The drawdown will likely need additional funds from Congress, the officials told lawmakers, as per CNN.
