Israel-Gaza live updates: Houthis claim 'hypersonic' missile attack on Israel

On Sunday, the Israel Defense Forces released the results of its investigation into the circumstances surrounding the deaths of three hostages, whose bodies were recovered from Gaza by IDF forces in December.

The three hostages -- two soldiers, Ron Sherman and Nik Beizer, and civilian Elia Toledano -- were killed "as a byproduct" of an Israeli airstrike on the compound where they were being held, according to the investigation. The IDF said the strike was targeting a Hamas commander, and that they believed the hostages were being held elsewhere.

"The findings of the investigation suggest a high probability that the three were killed as a result of a byproduct of an IDF airstrike, during the elimination of the Hamas Northern Brigade commander, Ahmed Ghandour, on November 10th, 2023," the IDF said Sunday in a statement.

Israeli Prime Minister Benjamin Netanyahu vowed to retaliate against the Houthi movement after a missile fired from Yemen fell in central Israel on Sunday morning.

"This morning, the Houthis launched a surface-to-surface missile from Yemen at our territory," Netanyahu said before a cabinet meeting. "They should know that we exact a high price for any attempt to attack us."

"Whoever needs a reminder of this, is invited to visit the port of Hodeidah," the prime minister added, referring to Israel's bombing of the strategic Yemeni port in July after a Houthi drone strike killed one person in Tel Aviv.

"Whoever attacks us will not evade our strike," Netanyahu said.

The Houthi movement confirmed responsibility for a missile attack on Israel on Sunday, saying in a statement posted to social media that the attack targeted "an important military target" in the Tel Aviv region.

The Houthi statement said it fired a "new hypersonic ballistic missile" which flew some 1,267 miles in less than 12 minutes. Israeli anti-missile defenses "failed to intercept" the weapon, the statement said.

"The Israeli enemy must expect more strikes," the Houthis added.

The Israel Defense Forces confirmed to ABC News that its defenses did not intercept the missile fired from Yemen, which it said "fell in an open area" and caused no casualties.

Around 40 "projectiles" crossed into Israel from Lebanon on Sunday morning, the Israel Defense Forces said.

"Some of the projectiles were intercepted and the rest fell in open areas," the IDF said in a statement. "No injuries were reported. Israel Fire and Rescue Services are currently operating to extinguish fires that were caused by fallen projectiles in open areas."

"Simultaneously, an explosive UAV was identified crossing from Lebanese territory," which fell near the northern border town of Metula, the IDF said. "No damage was caused in the area of the community and no injuries were reported."

Israeli jets and artillery units attacked "several areas" in southern Lebanon overnight, the IDF added.
