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."

On the morning of Oct. 7, sirens echoed across Israel as Hamas terrorists began a full-fledged surprise attack from the air, sea and ground. Hundreds of armed Hamas fighters stormed into Israel from Gaza, charging into cities and gunning down citizens.
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.

Ronen Bar, director of Israel's Shin Bet security service, said in a letter, "We were unable to generate a sufficient warning" for Hamas' attack.
"As the one who is at the head of the organization -- the responsibility for this is mine," he wrote.
Bar said there will be time for an investigation, but for now, Israelis are fighting.

A large group of protesters are rallying outside the White House calling for a cease-fire in Gaza.
More than 30 people have been arrested, according to the U.S. Secret Service.
The organizers of the rally said protesters came from all over the country to "protest for peace." Two demonstrators said they felt President Joe Biden's handling of the crisis has been "shameful" and "catastrophic."
The president has emphasized that Hamas does not represent all Palestinian people, who are also suffering, but some protesters told ABC News they didn't think Biden's language was strong enough.

Secretary of State Antony Blinken and Israeli Prime Minister Benjamin Netanyahu sheltered in a bunker for five minutes with the war cabinet and the rest of their meeting participants after rocket sirens went off in Tel Aviv on Monday, according to State Department spokesperson Matt Miller.
The meeting has since been moved and participants are going to an Israel Defense Forces command center to continue their discussions, Miller said.
Blinken returned to Israel on Monday to meet with Netanyahu. Miller said earlier that Blinken discussed in their meeting his "firm support" of Israel's right to defend itself and efforts to provide humanitarian aid and free hostages.

If these units are deployed, their purpose would be to serve as a deterrent.
