During an engagement:
…
4. Don’t kill enemy combatants who are wounded, who could no longer fight or who have already surrendered. By International Humanitarian Law, it is authorized to neutralize enemy forces by reasonable means while in combat. An enemy who wields a firearm and considered a threat is still a military objective and thus considered an authorized target. As long as he is wielding his firearm, he can still be considered as target for neutralization. But as soon as he drops his firearm, raises his hand or a white cloth that is a gesture of symbol of surrender, he can no longer be shot.

…
Surrender … – Any intention to surrender must be clearly expressed: raising arms, throwing away one’s weapons, bearing a white flag, etc.
