Some 7,000 people have fled from villages around the northeast Nigerian town of Chibok because of Boko Haram attacks, the International Organisation for Migration (IOM) said on Thursday.
The IOM said an estimated 4,449 people or 740 households have fled to Chibok itself since February 25, "seeking safety following attacks or threats of attacks in some neighbouring villages".
"These movements are in addition to the estimated 300 people who fled to Chibok town around February 10," it added in a briefing document seen by AFP.
"The staff also report that approximately 2,000 individuals fled from Kaya village, near Chibok town, to (the nearby town of) Damboa recently, in search of safety."
