Israel-Gaza updates: Israeli forces preparing for 'wide range of offensive plans'

Fighting is ongoing after Hamas launched an attack on Israel on Oct. 7.

At least 1,400 people have died and 3,400 others have been injured in Israel after the militant group Hamas launched an unprecedented incursion from air, land and sea on Oct. 7, Israeli authorities said.

In Gaza, 3,000 people have been killed and another 12,500 were injured, according to the Palestinian Ministry of Health.

Tensions are high with the prospect of ground war and evacuation orders for Gaza after the Israel Defense Forces called for "all residents of Gaza City to evacuate their homes" and "move south for their protection" early Friday, saying residents should move "and settle in the area south of the Gaza River." The announcement was made, according to the IDF, because it plans to "operate significantly in Gaza City in the coming days" and wanted "to avoid harming civilians."

Israeli forces responded by sending wave after wave of bombs into Gaza, killing thousands, trapping civilians and raising fears of a wider conflict in the Middle East.

US discussing whether to send 2nd carrier to eastern Mediterranean

United States officials are discussing whether a second U.S. aircraft carrier should be deployed to the eastern Mediterranean in the wake of the Israel-Hamas crisis, two U.S. officials confirmed.

The USS Dwight Eisenhower was previously scheduled to depart Norfolk, Virginia, later this week for the Middle East, via the Mediterranean Sea.

Officials must decide whether it will now remain in the Mediterranean and head to the east to join the USS Gerald R. Ford aircraft carrier -- which was deployed on Sunday -- or whether it will relieve the Ford.

Either way, the Eisenhower will soon be in the Mediterranean for the previously scheduled transit and a training rotation.

Hospitals, health system are at 'breaking point' in Gaza: WHO

Hospitals and the health system in the Gaza Strip are at a "breaking point," the UN World Health Organization said in a release Thursday.

"Hospitals have only a few hours of electricity each day as they are forced to ration depleting fuel reserves and rely on generators to sustain the most critical functions," the WHO said in the release. "Even these functions will have to cease in a few days, when fuel stocks are due to run out."

WHO said it documented 34 attacks on health care in Gaza since Saturday, Oct. 7. These attacks have resulted in "the death of 11 health workers on duty, 16 injuries and damages to 19 health facilities and 20 ambulances," the release said.
