Is the archer liable for expiation and blood money when a hostile combatant (*harbi*) uses a Muslim as a shield after the arrow has been shot?

If a hostile combatant uses a Muslim as a shield after the arrow has been loosed, the archer is subject to expiation (*kaffarah*). Regarding the blood money (*diyah*) payable by the archer's *aqilah* (kin group), there are two established narrations (rulings).
