For its part, Hamas’s military wing, while taking credit for the operation, said on Saturday that it had no information about the lieutenant and had lost contact with its squad, suggesting that all involved were dead. On Friday, Israeli forces immediately used a protocol for captured soldiers known as “Operation Hannibal” to pursue the Hamas squad into the tunnel and try to cut off any possibility of escape.
Hannibal includes intense pursuit and an option to engage the enemy “even at risk of the soldier,” Colonel Lerner said.
