UPDATE 2: A Kano resident sent us this: "I wasn't there but I know of the first place they went to in BUK! There is a Federal Government-assisted IT infrastructure site inside BUK old site that they first went to. They told the legionnaires guarding that they were there to bomb the building because it belonged to the Federal Government."
"After much begging and quoting of the Quran by the aged legionnaires, Boko Haram left and about 20 minutes later, they started bombing the chaplain and shootings broke out.
"Meanwhile, the area has been cordoned off by late arriving security."
Update1: The explosion started around 8 a.m. They attacked theatres 2 & 3, where the christians normally have their services.
Witnesses say the they gun shots lasted for more than 30 minutes. They said two bombs went off around the two theatres which are situated in between the faculties of medicine and science in the Bayero University.
The Joint Task Force, which is overseeing security in the city didn't arrive until 20 minutes after the gunmen had left. A witness said the attackers were seven in number.
The place is now calm, he said.
We spoke to one clergy, who said he was conducting service in one of the theatres when the blasts went off.
He said it occurred 30 metres away from where he stood, adding that what scarred him most was the gunshots that followed the bombing.
He admitted casualties but is still in state of shock and could not tell how many.
