KANO, Nigeria — Gunmen attacked church services on a university campus Sunday in northern Nigeria, using small explosives to draw out and gun down panicking worshippers in an assault that killed at least 16 people, officials said.
The assault left many others seriously wounded, Mr. Idris said.
“By the time we responded, they entered [their] motorcycles and disappeared into the neighborhood,” he said.
After the attack, police and soldiers cordoned off the campus as gunfire echoed in the surrounding streets.
Abubakar Jibril, a spokesman for Nigeria's National Emergency Management Agency, said security forces refused to allow rescuers to enter the campus. Soldiers also turned away journalists from the university.
Andronicus Adeyemo, an official with the Nigerian Red Cross, said a canvass of local hospitals and morgues showed the attack killed at least 16 people. Several people suffered injuries, though the aid agency did not immediately have an exact figure, Mr. Adeyemo said.
No group immediately claimed responsibility. However, Mr. Idris said the attackers used small explosives packed inside of aluminum soda cans for the assault, a method previously used by a radical Islamist sect known as Boko Haram.
Boko Haram is waging a growing sectarian battle with Nigeria’s weak central government, using suicide car bombs and assault rifles in attacks across the country’s predominantly Muslim north and around its capital, Abuja. Those killed have included Christians, Muslims and government officials.
The sect has been blamed for killing more than 450 people this year alone, according to an Associated Press count.
Diplomats and military officials say Boko Haram has links with two other al Qaeda-aligned terrorist groups in Africa. Members of the sect also reportedly have been spotted in northern Mali, which Tuareg rebels and hard-line Islamists seized control of over the past month.
In January, a coordinated assault on government buildings and other sites in Kano by Boko Haram killed at least 185 people. Since then, the sect has been blamed for attacking police stations and carrying out smaller assaults in the city.
On Thursday, the sect carried out a suicide car bombing at the Abuja offices of the influential newspaper This Day and a bombing at an office building it shared with other publications in the city of Kaduna. At least seven people were killed in those attacks.
Late Thursday, gunmen also bombed a building at the campus of Gombe State University, though authorities said no one was injured in the attack.
