Abuja, Nigeria (CNN) Some 337 students are still unaccounted for after gunmen attacked a school in northern Nigeria over the weekend, a government official told CNN on Monday. Local police said a large number of attackers riding motorbikes ambushed the all-boys Government Science Secondary School in Kankara late Friday, in a possible kidnapping-for-ransom attempt. The apparent kidnappers are making a demand via a teacher at school, Abdu Labaran, the director general of media for the governor of Nigeria's Katsina state, said Monday. "The abductors of the Kankara students have contacted a teacher and asked him to tell the government to stop the helicopter surveillance. They have not asked for ransom," said Labaran, who added that the military had deployed in the area to search for the boys.
