WASHINGTON (AP) — President Donald Trump on Thursday warned Hamas "we will have no choice but to go in and kill them" if internal bloodshed persists in Gaza.

The grim warning from Trump came after he previously downplayed the internal violence in the territory since a ceasefire and hostage deal between Israel and Hamas went into effect last week in the two-year war.

Trump later clarified he won't send U.S. troops into Gaza after launching the threat against Hamas.

"It's not going to be us," Trump said in an exchange with reporters. "We won't have to. There are people very close, very nearby that will go in and they'll do the trick very easily, but under our auspices."

The president did not specify if he was speaking of Israel, but action by Israeli forces could risk violating terms of the ceasefire agreement.

The president's shift in tone with Hamas was notable.

Trump said Tuesday that Hamas had taken out "a couple of gangs that were very bad" and had killed a number of gang members. "That didn't bother me much, to be honest with you," he said.

The Republican president did not say how he would follow through on his threat posted on his Truth Social platform, and the White House did not immediately respond to a request for comment seeking clarity.

But Trump also made clear he had limited patience for the killings that Hamas was carrying out against rival factions inside the devastated territory.

"They will disarm, and if they don't do so, we will disarm them, and it'll happen quickly and perhaps violently," Trump said.

The Hamas-run police maintained a high degree of public security after the militants seized power in Gaza 18 years ago, while also cracking down on dissent. They largely melted away in recent months as Israeli forces seized large areas of Gaza and targeted Hamas security forces with airstrikes.

Powerful local families and armed gangs, including some anti-Hamas factions backed by Israel, stepped into the void. Many are accused of hijacking humanitarian aid and selling it for profit, contributing to Gaza's starvation crisis.

The ceasefire plan introduced by Trump had called for all hostages — living and dead — to be handed over by a deadline that expired Monday. But under the deal, if that didn't happen, Hamas was to share information about deceased hostages and try to hand them over as soon as possible.

Israeli Prime Minister Benjamin Netanyahu said Wednesday that Israel "will not compromise" and demanded that Hamas fulfill the requirements laid out in the ceasefire deal about the return of hostages' bodies.

Hamas' armed wing said in a statement Wednesday that the group honored the ceasefire's terms and handed over the remains of the hostages it had access to.

The United States announced last week that it is sending about 200 troops to Israel to help support and monitor the ceasefire deal in Gaza as part of a team that includes partner nations and nongovernmental organizations. But U.S. officials have stressed that U.S. forces would not set foot in Gaza.

Israeli officials have also been angered by the pace of the return of the remains of dead hostages the militant group had been holding in captivity. Hamas had agreed to return 28 bodies as part of the ceasefire deal in addition to 20 living hostages, who were released earlier this week.

Hamas has assured the U.S. through intermediaries that it is working to return dead hostages, according to two senior U.S. advisers. The advisers, who were not authorized to comment publicly and briefed reporters on the condition of anonymity, said they do not believe Hamas has violated the deal.
