An ambush attack by Boko Haram terrorists in Nigeria against an oil exploration team has killed more than 50 people, according to sources, who said the death toll could rise further.
The terrorists attacked a convoy of specialists from the Nigerian National Petroleum Corporation (NNPC) in the Magumeri area of northeastern state of Borno on Tuesday, sources said on Friday.
Initial reports from the army, which suggested that the ambush had been an abduction attempt, put the number of casualties at a mere ten. Reports later claimed that the abducted geologists and surveyors, who worked at the University of Maiduguri, had been rescued.
But details gradually emerged showing that the attack had been an ambush that killed many more people than originally reported.
