The wholesale slaughter of Christians continues.

(ABC News) — Police say at least eight people have been killed in an attack on a church service at a Nigerian university in the northern city of Kano.

Explosions and gunfire rocked Bayero University, with witnesses reporting that two church services were targeted as they were being held on campus.

One of the services was being held outdoors, while the second was inside a building, but with an overflow audience outside, witnesses said.

Officials were unable to confirm casualty figures, but one correspondent counted six bullet-riddled bodies near one of the two sites and said other bodies had been seen on a roadside by the university.

Musical instruments and half-eaten meals could be seen at the site of one of the services.

An army spokesman confirmed the attack but could not provide a casualty toll.

Lieutenant Iweha Ikedichi said it appeared the attackers used bombs and gunfire in the assault.

There was no immediate claim of responsibility, although the attack was similar to others carried out by the Islamist group Boko Haram.

Update: Death toll now at 16.

Kano: 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 attackers targeted an old section of Bayero University’s campus where religious groups use a theater and other areas to hold worship services, Kano state police spokesman Ibrahim Idris said. The assault left many others seriously wounded, Idris said.

“By the time we responded, they entered (their) motorcycles and disappeared into the neighborhood,” the commissioner 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 canvas of local hospitals and morgues showed the attack killed at least 16 people. A number of people suffered injuries, though the aid agency did not immediately have an exact figure, Adeyemo said.
