GAZA/JERUSALEM/RAMALLAH – Al-Qassam Brigades, the armed wing of Hamas, handed over the body of Shiri Bibas, an Israeli hostage, to the International Committee of the Red Cross (ICRC) on Friday, according to a senior Hamas official, after Israeli authorities determined that a body returned by the Palestinian group on Thursday was not her.

The official, speaking on condition of anonymity, explained that the mix-up occurred due to the chaos caused by Israeli airstrikes, which led to the misidentification of remains.

"It was an unintentional mistake, as the body of Shiri was mixed with others due to Israeli attacks on the area where it was located," he said.

On Thursday, al-Qassam transferred the remains of four Israeli hostages – presumably Shiri Bibas, her two sons, Ariel and Kfir, as well as retired journalist Oded Lifshitz – back to Israel through the ICRC.

The four hostages were abducted to Gaza during a Hamas-led attack on southern Israel on Oct 7, 2023.

However, later on Thursday, after conducting forensic analysis on the four bodies, Israeli authorities announced that the body initially believed to be Shiri Bibas did not match her DNA.

On Friday, Israeli Prime Minister Benjamin Netanyahu threatened that Israel will seek revenge against Hamas over its failure to hand over Shiri's body, saying, "We will ensure that Hamas pays the full price for this cruel and evil violation of the agreement."

The same day, Netanyahu the Tulkarm refugee camp in the West Bank, joining Israeli military forces operating in the area.

In a recorded video statement, Netanyahu said that in response to three blasts late on Thursday, which ripped through empty buses in the Tel Aviv area, Israel has increased its forces in the West Bank and will conduct additional operational activity against "terror centers".

"In the past year, we have greatly increased our activity ... This is a significant work against the desire of Hamas or others to harm us," he said.

Israel's state-owned Kan TV News reported that the Israel Security Agency has arrested two suspects, residents of the Tel Aviv suburbs, on suspicion of involvement in transporting the attackers to the buses.

Meanwhile, a Palestinian medical official said that a Palestinian girl was shot and killed by Israeli army fire near the Jenin refugee camp in the northern West Bank on Friday.

Wissam Bakr, director of Jenin Governmental Hospital, said Riyas al-Amouri, a 13-year-old girl, was killed after being shot by the Israeli army in the back while inside her family's home.

Since the escalation of tensions on Oct 7, 2023, the West Bank has witnessed increasing violence, with more than 900 Palestinians killed by Israeli forces, according to the Palestinian Ministry of Health.

The recent month has witnessed a further escalation of Israeli raids in the West Bank, which has prompted Palestinian condemnations.

The Israeli military operation in the Jenin camp has now extended for 32 days, marked by ongoing demolitions and the bulldozing of homes.

Palestinian Deputy Prime Minister and Minister of Information Nabil Abu Rudeineh said earlier this week that Israeli forces were conducting a systematic campaign of destruction in the cities of Jenin and Tulkarm and their surrounding camps.

Abu Rudeineh said the campaign has resulted in the deaths of dozens of citizens while the international community remains silent about Israel's plans for "racist annexation and territorial expansion.”
