More than 50 freed Israeli captives have urged Prime Minister Benjamin Netanyahu to fully implement the Gaza ceasefire deal and secure the release of those still held in the Palestinian territory, AFP reports.

“We who have experienced the inferno know that a return to war is life-threatening for those still left behind,” a group of 56 freed hostages said in a letter posted on the social media platform Instagram. “Implement the agreement in full, in one single manoeuvre.”

Among those to sign the letter was Yarden Bibas, whose wife and two young sons died while held captive in Gaza.
