Nigeria’s Military Manual (1994), in a part dealing with the 1949 Geneva Convention I, states that reprisals “are prohibited ‘against the … personnel … protected by the convention’ (Art. 46)”. 

Nigeria’s Manual on the Laws of War, which states that “[i]t is prohibited to take measures of reprisal against prisoners of war as a retaliation for [a] violation of the Laws of War by the enemy”, also provides for the same protection and benefits to be granted, as a minimum, to medical personnel and military chaplains captured by the enemy.
