US expects Israeli-Hamas war to escalate, rushes strike group to region: Live updates

The Biden administration expects the Israeli-Hamas war to expand and U.S. personnel could be targeted, two members of the Cabinet warned amid an increasing U.S. military presence in the region.

The safety concerns were raised just days after Defense Secretary Lloyd Austin announced the U.S. will redeploy a strike group to the Persian Gulf and send additional air defense systems to the region. And last week Austin ordered 2,000 troops to prepare for deployment to the Middle East amid increasing tensions since Hamas militants stormed across the border in a killing rampage of Israeli citizens Oct. 7.

The Biden administration has warned Iran, Hezbollah and other foes of Israel to stay out of the war. But Defense Secretary Lloyd Austin Secretary of State Antony Blinken said that might not happen.

"What we're seeing is the prospect of a significant escalation of attacks on our troops and our people throughout the region," Austin said Sunday on ABC's "This Week." He said U.S. troops are doing "what's necessary" to ensure they have the ability to respond.

Secretary of State Antony Blinken echoed Austin's concerns, telling NBC's "Meet the Press" that "we expect that there's a likelihood of escalation" by Iranian proxies directed against U.S. forces

"We are taking steps to make sure we can effectively defend our people and respond decisively if we need to," Blinken said.

Blinken said he does not want to see a second or third front develop, which could happen if Lebanon-based Hezbollah joins the fray.

"We don't want to see our forces or our personnel come under fire," he said. "But if that happens we are ready for it

Is US behind delay in Israeli ground invasion of Gaza?

The United States has urged Israel to delay its much-anticipated ground invasion of Gaza to encourage hostage negotiations, improve the flow of humanitarian aid and to allow the U.S. to prepare for attacks on "U.S. interests" in the region, according to multiple media reports.

The New York Times and CNN, citing Biden administration sources they did not name, said the U.S. remains fully supportive of Israel in the war and supports the planned ground invasion.

The U.S. also has been leading the charge for establishment of a steady flow of aid to Gaza from Egypt.
