Hamas and Israel will conduct their fourth swap of the Gaza ceasefire today, with Hamas releasing three Israelis including the father of the two youngest hostages, in exchange for 183 Palestinians held in Israeli jails, AFP reports.

The Israeli hostages to be freed on Saturday are Yarden Bibas, Keith Siegel, who also holds US citizenship, and Ofer Kalderon, who also has French nationality, according to the Hostages and Missing Families Forum campaign group.

In return, Israel will release 183 prisoners, the Palestinian Prisoners’ Club advocacy group said, more than double the initially reported figure of 90.

Among those taken were the wife and two children of Yarden Bibas. Hamas has declared the three dead, but Israeli officials have not confirmed this.

The two Bibas boys — Kfir, the youngest hostage, whose second birthday fell in January, and his older brother Ariel, who turned five in August — have become symbols of the ordeal endured by hostages in Gaza.

The children were taken along with their mother, Shiri Bibas.
