More than 25,000 people have been killed in the Gaza Strip since the beginning of the Israel-Hamas war, the Gaza Ministry of Health said Sunday.

At least 62,681 people have been injured since the war began, said the ministry, which operates under the Hamas Authority.

A ministry spokesperson said at least 178 bodies were brought to hospitals in the last day.

Several relatives of hostages being held by Hamas in Gaza protested outside Israeli Prime Minister Benjamin Netanyahu's home on Saturday, demanding the government take more steps to free the captives.

Some protesters camped out in front of his home, in the coastal town of Caesarea.

More than 130 hostages are still held in captivity, according to Israeli officials.

The fatal shooting of a 17-year-old Palestinian-American in the West Bank on Friday remains under investigation, as mourners gathered Saturday for the teen's funeral.

Tawfiq Ajaq was killed near the city of Ramallah, according to the Defense for Children International - Palestine advocacy group.

Israeli police said they received a report Friday regarding a "firearm discharge, ostensibly involving an off-duty law enforcement officer, a soldier and a civilian." Police did not identify who fired the shot but described the shooting as taking place over people "purportedly engaged in rock-throwing activities" along a main highway.

Israeli police said its internal affairs department is investigating the incident.

An initial assessment by the Defense for Children International - Palestine also found that it was unclear who fired the shot that struck the teen.

A State Department spokesperson confirmed the death of a U.S. citizen civilian in the West Bank on Friday.

Asked about the incident at a briefing on Friday, U.S. National Security spokesman John Kirby said White House officials "don't have perfect context about exactly what happened here" but are "seriously concerned about it."

"We're going to be in constant touch with counterparts in the region to get more information," he said.

The teen's funeral was held Saturday in the West Bank. His friends said his family had returned to their home village in the Israeli-occupied territory from Harvey, Louisiana, about a year ago, according to Reuters.

President Joe Biden and Israeli Prime Minister Benjamin Netanyahu spoke on Friday, according to the White House.

This was the first known call between the two leaders since Dec. 23, 2023.

Biden and Netanyahu spoke about a two-state solution, among other things, one day after Netanyahu expressed opposition to a Palestinian state.

"The president still believes in the promise and the possibility of a two-state solution," White House national security spokesperson John Kirby said Friday. "He recognizes that it's going to take a lot of hard work. It's going to take a lot of leadership, there in the region, particularly, on both sides of the issue. And the United States stands firmly committed to eventually seeing that outcome."

"We're not going to agree on everything," Kirby said. He later added that Netanyahu’s comments will not change Biden’s "strong conviction" that “the best long-term solution for regional security, particularly the security of the Israeli people, is a free, independent Palestinian state that they can live in peace and security with -- and this is an important caveat -- with Israel's security also guaranteed."

Though Biden will continue to press for a two-state solution, "this isn't about trying to twist somebody's arm or force a change in their thinking," Kirby said.

Kirby said Netanyahu’s comments did not trigger the two leaders’ Friday call.

"This was a call that we've been, actually, trying to land on the schedule for quite a bit of time," he said.
