IDF field observers Daniella Gilboa, Karina Ariev, Naama Levy, Agam Berger and Liri Albag were held for a long period of time during their captivity in an apartment in Gaza City, where a senior Hamas military wing official was staying. He used them as human shields, and was a "dominant figure" in the apartment hide-out. Some of them discovered that the same figure was a senior Hamas official only after they returned from captivity.
