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.

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.”

Israeli National Security Adviser Tzachi Hanegbi said Tuesday that officials plan to create "safe zones" in southern Gaza as the only places where residents can receive humanitarian aid.

The aid would be "on one condition," Hanegbi said in Hebrew. "If this aid does not reach civilians, but goes to murderers, [the safe zones] will simply not exist."
