ALGIERS (Reuters) - Algeria said on Wednesday that Moroccan bombardment had killed three of its citizens in the border area between Mauritania and the disputed territory of Western Sahara and warned it would "not go unpunished".

Monday's incident underscores the risks of escalation between the powerful North African rivals after months of deteriorating relations tied to the conflict in Western Sahara.
