Germany will not authorize any exports of military equipment that could be used in Gaza "until further notice," Chancellor Friedrich Merz announced Friday, in a strikingly quick response by one of Israel's strongest international backers to a decision by Prime Minister Benjamin Netanyahu's Cabinet to take over Gaza City.

The move by Germany, which has previously stopped short of tougher lines against Israel's government taken by some of its European Union allies, appeared likely to further isolate Israel in the wake of the controversial military takeover plan that has been decried by the United Nations and supporters of Israeli hostages still held in Gaza.

Nations around the world on Friday expressed concern over Israeli plans to wrest control of Gaza City, saying that it would only worsen the conflict and lead to more bloodshed.

Here is what they said:

Hamas warned the Israeli government on Friday that seizing control of Gaza City would amount to "sacrificing" the hostages still being held in the Palestinian territory.

"The decision to occupy Gaza confirms that the criminal (Israeli Prime Minister Benjamin) Netanyahu and his Nazi government do not care about the fate of their captives," the group said in a statement. "They understand that expanding the aggression means sacrificing them."

Turkey on Friday urged the international community to prevent Israel's plan to take control of Gaza City, saying it was a "heavy blow" to peace and security.

"We call on the international community to fulfill its responsibilities to prevent the implementation of this decision, which aims to forcibly displace Palestinians from their own land," the foreign ministry said in a statement.

Israel said early Friday that it plans to take over Gaza City, in another escalation of its 22-month war with Hamas. The decision, made after a late-night meeting of top officials, drew Palestinian rejection, fueled mounting international calls to end the war and provoked worries in Israel over the fate of hostages still held by Hamas.

Israel's air and ground war has already killed tens of thousands of people in Gaza, displaced most of the population, destroyed vast areas and pushed the territory toward famine. Another major ground operation would almost certainly exacerbate the humanitarian catastrophe.

Relatives of Israeli hostages set sail on Thursday in a flotilla to approach the besieged Gaza Strip, according to an AFP journalist aboard one vessel, with organizers saying they hoped to "get as close as possible to their loved ones".

More than 20 people boarded several boats that departed from the coastal city of Ashkelon carrying yellow flags and posters bearing the images of the hostages, as they shouted their names.

Truck drivers trying to deliver aid inside Gaza say their work has become increasingly dangerous in recent months as people have grown desperately hungry and violent gangs have filled a power vacuum left by the territory's Hamas rulers.

Crowds of hungry people routinely rip aid off the backs of moving trucks, the local drivers said. Some trucks are hijacked by armed men working for gangs who sell the aid in Gaza's markets for exorbitant prices. Israeli troops often shoot into the chaos, they said.

At Shifa hospital in the Gaza Strip, nothing is sterilized, so Dr. Jamal Salha and other surgeons wash their instruments in soap. Infections are rampant. The stench of medical waste is overwhelming. And flies are everywhere.

Without painkillers, patients moan while lying on metal beds lining the corridors. There's no electricity and no ventilation amid searing heat, leaving anxious visitors to fan bedridden relatives with pieces of cardboard.

At least 38 Palestinians were killed overnight and into Wednesday in the Gaza Strip while seeking aid from United Nations convoys and sites run by an Israeli-backed American contractor, according to local health officials. The Israeli military said it had fired warning shots when crowds approached its forces.

The latest deaths came as Prime Minister Benjamin Netanyahu was expected to announced further military action — and possibly plans for Israel to fully reoccupy Gaza. Experts say Israel's ongoing military offensive and blockade are already pushing the territory of some 2 million Palestinians into famine.

Israeli Prime Minister Benjamin Netanyahu is considering ordering the full reoccupation of the Gaza Strip, according to Israeli media, a move that would draw fierce opposition internationally and within Israel.

It would mark a stunning escalation of the nearly 22-month war in the territory that has already been largely destroyed and where experts say famine is unfolding. It would put the lives of countless Palestinians and about 20 living hostages at risk, and deepen Israel's already stark international isolation.
