About 100 relatives and families of the hostages, who are still held captive in the Gaza Strip, are heading to The Hague today, Wednesday, to file a complaint against Hamas before the International Criminal Court on charges of committing "crimes against humanity," according to representatives of them.

Israel estimates that about 130 hostages are still held in Gaza, including 29 believed to have died, out of about 250 people who were kidnapped on October 7 during a Hamas attack on southern Israel.

Ofri Peebas, the sister of one of the hostages, said before boarding a private flight to The Hague: "This is not just our story, if we do not stop this, tomorrow it will be the story of the whole world," adding, "All humanity must remain firm in facing a global terrorist army of which Hamas is considered one of its brigades carrying out its missions."

Hostages’ families spokesperson Haim Rubenstein confirmed during a televised press conference from Ben Gurion Airport in Tel Aviv that a complaint will be filed with the International Criminal Court "against Hamas members and their collaborators to ensure they pay a heavy price for the crimes against humanity they have committed and continue to commit."

The hostages’ families continue to pressure the Israeli authorities aiming to reach the release of their relatives who have been held for more than four months.

A week-long truce in November allowed for the release of 105 hostages in exchange for 240 Palestinian detainees from Israeli prisons.

The International Criminal Court was established in 2002 and is the only independent court in the world that was created to investigate the most serious crimes including genocide, war crimes, and crimes against humanity.

On Monday, the ICC Prosecutor Karim Khan expressed concern about reports of a possible attack by the Israeli army on the city of Rafah in the far south of the Gaza Strip, threatening to prosecute any party that violates international laws.

Khan called for the release of all hostages held by Hamas, noting that "this matter also represents an important focus of our investigations."

Meanwhile, Egypt hosted on Tuesday the Director of the US Intelligence Agency William Burns, Mossad Chief David Barnea, and Qatari Prime Minister Mohammed bin Abdulrahman Al Thani for talks regarding a truce including the release of new hostages.
