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.
Former President Barack Obama released a statement Monday evening condemning Hamas' attack on Israel over the weekend.
"All Americans should be horrified and outraged by the brazen terrorist attacks on Israel and the slaughter of innocent civilians," Obama said in his statement. "We grieve for those who died, pray for the safe return of those who’ve been held hostage, and stand squarely alongside our ally, Israel, as it dismantles Hamas."

White House spokesperson John Kirby echoed this sentiment to ABC News' Linsey Davis.
"We don't really know whether they're just missing somewhere, or are lost, or whether they're being held hostage. I think we have to accept the possibility that at least some of them are being held hostage by Hamas," he said.
Of the Americans previously confirmed dead, a State Department official said they were all thought to be dual U.S.-Israeli citizens primarily residing in Israel.
Staffers at the U.S. Embassy in Israel are fully accounted for and are communicating with impacted Americans around the clock over the telephone and via the online form the department launched for U.S. nationals who believe their family members are among those missing, according to the agency.
