The area identified by the sources is a remote, disputed section of the border known for illegal or artisanal gold mining. The target is described as a mine or a gold-miners' camp.
The death toll of at least 72 was reported by a Sudan-based rights group and picked up by Deutsche Welle, Al Jazeera and France 24. The figures, however, remain based on the group's report.
Al Jazeera also reports that more than 50 people were reportedly wounded. The number of wounded appears only in the report provided by the broadcaster among the available sources.
Emergency Lawyers accused the Egyptian air force of carrying out the attack, according to France 24. The identity of the party responsible for the raids has not been confirmed, however.
According to the available information, neither Egypt nor Sudan had issued an official comment on the accusations and the attacks. The absence of an official position leaves the question of responsibility unresolved.
The reports agree on the general area of the incident and on the fact that a mining site was hit, but they do not specify the facility's exact location along the border. The sources also alternate between singular and plural formulations when referring to the attack or attacks.
France 24, citing AFP, finally reports that the account could not be independently verified. Both the final death toll and responsibility for the operation therefore remain to be established.
