Nigerian terror group Boko Haram has pushed on after a rampage through the north of the country that killed more than 2000 people to attack an army base in neighbouring Cameroon.
At least one Cameroonian soldier was killed in the cross-border attack, according to local journalists, though Cameroonian authorities said the assault on the base in the town of Kolofata had been repulsed.
In a shock development, five suspected child suicide bombers blew themselves up in a market in the town of Potiskum in Yobe state , northeast of Nigeria on Sunday, killing four people in the second attack in two days .
A trader at the market said the bombers were about 10 years old. "I saw their dead bodies. They are two young girls of about 10 years of age ... you only see the plaited hair and part of the upper torso," the trader said.
The town was hit by a suicide bomber in November when at least 48 people, mainly pupils, were killed during assembly.
Sunday's explosions came a day after a bomb strapped to a girl exploded in a market place in Maiduguri, killing at least 16 people.
