Military soldiers photographed children and teachers in school in Valayankattu and Kaakkaiyinkulam in Mannar district, BBC Tamil reported.
Entering schools during lessons times, the military also gathered information about the students, teachers and headteacher.
Condemning the incident, Joseph Stalin of the Ceylon Teachers' Union said it had spread fear amongst staff and families of the children, he called on the Northern Province's Education Minister and the Chief Minister C.V.Wigneswaran to take immediate action.
"If information about schools is needed, it would be normal practice to obtain the information from the provincial educational secretary, instead of doing that, for the military to go to schools whilst lessons are taking place and act in this way is wrong," BBC Tamil quoted Mr. Stalin as saying.
