PHOTO:AFPFour people were killed in a blast at a camp for people displaced by the Boko Haram conflict in northeast Nigeria, Doctors Without Borders (MSF) said on Tuesday.
A Nigerian military source confirmed the incident and put the death toll at five.
The explosion happened at about 12:30 pm (1130 GMT) on Monday in the border town of Pulka, in the Gwoza area of Borno state, where a Spanish team from the medical charity is providing healthcare.
It was initially thought the blast was caused by a suicide bomber.
But a military source in the town said later that examination of the blast scene indicated it may have been caused by a mortar shell.
Ivan Munoz, an MSF spokesman in Borno state, told AFP in an email that the blast killed three people and injured seven, one of whom subsequently died after being admitted for treatment.
“All our staff are safe. The team is monitoring the security situation to assess any further steps,” he added.
