Israel-Gaza updates: Biden speaks with Netanyahu about hostages' release, Gaza humanitarian assistance

An Israel Defense Forces tank accidentally fired and hit an Egyptian post adjacent to the border in the area of Kerem Shalom, the IDF said in a statement Sunday.

The incident is being investigated and the details are under review, the IDF added.

"During the ongoing clashes in the Gaza Strip today, Sunday, an Egyptian border watchtower was accidentally hit by fragments of a shell from an Israeli tank, resulting in minor injuries to some border watchmen. The Israeli side has immediately expressed regret over the unintentional incident. An investigation into the circumstances of the incident is underway," an Egyptian military spokesperson said in a statement.

An Egyptian security forces source said five military personnel and eight civilians were injured.

Eligible family members and non-emergency government personnel from the U.S. Embassy in Baghdad and the consulate general in Erbil, Iraq, have been ordered to depart the country “due to increased security threats against U.S. government personnel and interests," the U.S. State Department said Sunday.

Under the State Department’s travel advisory system, Iraq remains at Level 4, the highest warning level, where it has been for many years. The State Department said the order for non-emergency U.S. government personnel and eligible family members at the Baghdad Embassy and Consulate General was issued on Friday.

Intensifying Israeli airstrikes against Hamas targets in Gaza and a possible ground assault “may increase calls for violence in the United States,” according to a new intelligence assessment by the Department of Homeland Security that also noted there has already been a rise in hate crimes against Jewish, Muslim and Arab communities.

“Targeted violence attacks may increase as the conflict progresses,” the assessment said.

A separate memo to law enforcement agencies in Washington D.C., said, the escalation in the latest war between Israel and Hamas almost certainly will increase the threat of "terrorism and targeted violence” in the United States.

“While we currently have no intelligence to suggest that homegrown violent extremists and unaffiliated lone actors are planning any attack on the District or U.S. at large, foreign terrorist organizations are likely to increase the production of propaganda compelling U.S.-based actors to conduct attacks,” the memo said.

Likely targets include houses of worship, First Amendment-protected demonstrations and events, or U.S. military assets, the memo said. It mentioned an increase in swatting calls targeting Jewish houses of worship in Massachusetts, Pennsylvania and Rhode Island with hoax bomb threats.

The memo adds, "We expect to remain in a heightened threat environment in the near-to-medium term -- even if a diplomatic solution to the crisis is found.”

Republican presidential candidate Tim Scott doubled down on his accusations Sunday that President Joe Biden has "blood on his hands" after the Hamas' terror attack spurred a wider war.

The South Carolina senator has been a vocal critic of the United States agreeing to release some $6 billion in Iranian oil revenue in order to free five American detainees. The deal, arranged before the Oct. 7 Hamas attack, prompted the Biden administration to re-freeze the money after the terrorist group's rampage.

"Do not be surprised when the result of that $6 billion leads to more conflict in the Middle East," Scott told ABC "This Week" co-anchor Jonathan Karl.

"I'm saying with great clarity that weakness from the American president, plus the negotiations, leading to terrorist attacks by negotiating with the No. 1 state sponsor of terrorism in the world -- yes, it creates complicity," Scott said, repeating claims he made earlier this month.
