Baby Kfir Bibas is the youngest hostage remaining in the Strip. He was kidnapped with his brother Ariel - four years old - and his mother, residents of a kibbutz adjacent to Gaza.
His father, Yarden, was taken separately captive and also transferred to the enclave. Israeli Prime Minister Benjamin Netanyahu reacted to the images. "We will bring these kidnappers of babies and mothers to justice. They will not get away with it," he said in a statement released by his office.
