MAIDUGURI, Nigeria - Heavily armed Boko Haram Islamists kidnapped more than 100 girls from a school in northeast Nigeria, sparking a search by soldiers to track down the attackers, a security source and witnesses said Tuesday.
The unprecedented mass abduction in Borno state came hours after a bomb blast ripped through a crowded bus station on the outskirts of Abuja, killing 75 people, the deadliest attack ever in Nigeria's capital.
The violence underscored the serious threat the Islamists pose to Africa's most populous country, with the group capable of carrying out large-scale attacks in remote areas and massive bombings in major urban centres.
Gunmen stormed the Government Girls Secondary School in the Chibok area of Borno after sundown on Monday, torching several buildings before opening fire on soldiers and police who were guarding the school, witnesses said.
They ultimately overpowered the guards and entered the school, said Emmanuel Sam, an education officer based in Chibok who fled to the state capital Maiduguri after the attack.
The girls were then forced onto trucks and driven away by the attackers, multiple witnesses said.
A security source who requested anonymity said more than 100 girls were taken and blamed the attack on Boko Haram, a radical group whose name means "Western education is forbidden".
"We were able to follow the path of the truck and we found it broke down deep in the bush," the source told AFP.
"We are now trying to locate the whereabouts of the abducted girls," he added.
Some of the schoolgirls narrowly escaped their kidnappers by jumping off a truck in the middle of the night before running back to Chibok.
One of those who escaped said their opportunity to flee came when some of the gunmen became distracted after one of the vehicles in the convoy broke down.
"They tried to fix it," she told AFP by phone from Chibok on condition of anonymity. "It was at this moment that some of us jumped out of the vehicles and ran into the bush."
EU foreign policy chief Catherine Ashton "strongly" condemned the abductions, saying the 28-nation bloc stands with Nigeria in its struggle against terrorism.
"I am concerned by the increasing frequency and spread of terrorist attacks," she said in a statement.
"The EU stands with the people and the government of Nigeria in the fight against terrorism and violence and for the rule of law and human rights," Ashton added.
Boko Haram is blamed for killing thousands of people across north and central Nigeria since 2009 in an uprising aimed at creating a strict Islamic state in the north.
The group has carried out scores of school attacks, spraying gunfire on students in their sleep and bombing educational buildings across the north.
But a mass kidnapping specifically targeting girls is unprecedented in the group's rebellion.
