Trump hints at 'action' if Hamas doesn't return hostage bodies

The Israeli Prime Minister's Office issued a statement Sunday saying that Prime Minister Benjamin Netanyahu instructed the minister of defense and the heads of security establishment to "act forcefully against terrorist targets" in Gaza.

The statement comes after Israel and Hamas accused each other of violating the peace deal.

"Following Hamas's violation of the ceasefire, Prime Minister Netanyahu held a consultation with the Minister of Defense and the heads of the security establishment and instructed them to act forcefully against terrorist targets in the Gaza Strip," Sunday's statement read.

"Earlier today (Sunday), terrorists fired an anti-tank missile and gunfire toward IDF troops operating to dismantle terrorist infrastructure in the Rafah area, in southern Gaza, in accordance with the ceasefire agreement," according to a statement by the Israel Defense Forces (IDF).

"In response, the IDF has begun striking in the area to eliminate the threat and dismantle tunnel shafts and military structures used for terrorist activity. These terrorist actions constitute a blatant violation of the ceasefire agreement, and the IDF will respond firmly," the IDF statement continued.

Israeli officials on Sunday said the second set of remains returned overnight by Hamas were those of Suntaya Akrasi, a Thai citizen, who was killed by Hamas on Oct. 7, 2023.

"Suntaya, 30 years old at the time of his death, was abducted from the orchards of Kibbutz Be'eri," the Israel Defense Forces said on social media. "His death was pronounced on May 16th, 2024."

Hamas as of Sunday has handed over 12 sets of remains out of the 28 that had been in the militant group’s possession when the ceasefire came into effect, according to Israel.

Hamas has carried out "multiple attacks" against Israeli forces, an Israeli military official told ABC News,

"The terror organization Hamas carried out multiple attacks against Israeli forces beyond the yellow line," the official said. "The attacks included an RPG shot at a military force, and a sniper fire against a military force. Both of the incidents happened in an Israeli controlled area, east to the yellow line. This is a bold violation of the ceasefire."

Hamas officials said the militant group "rejects the allegations" made by the U.S. State Department, which warned Saturday of "credible reports" that Hamas may be violating the terms of its ceasefire with Israel.

Hamas in a statement called the allegations false and "Israeli propaganda."

It accused Israel of supporting criminal gangs that have wreaked havoc on Palestinian civilians, "spreading chaos and disrupting security."
