The Sacred Heart Minor Seminary in Jalingo, the Taraba State capital, has been shut for one week following an attack by suspected Fulani herdsmen.
Two Catholic priests were said to have been beaten up, while another was shot in the leg.
The herdsmen were said to be unhappy with security men in the seminary for trying to prevent them from grazing their cattle on the premises of the institution.
During the attack, which was said to have taken place on Monday, some students were reportedly injured and many cars destroyed.
The herdsmen were said to have shot continuously at the residence of the Rector, Rev. Fr. Emmanuel Atsue, and beaten up one Rev. Fr. Stephen Bakari.
Eyewitnesses said the windscreen of one of the vehicles belonging to one of the priests was smashed, while the herdsmen shot and injured one Rev. Fr. Cornelius Kobah in the leg.
While the persons injured were said to be receiving treatment at the Federal Medical Centre, Jalingo, it was not yet clear if anybody was killed.
