Clashes erupted in Kakapora area of south Kashmir's Pulwama district on Wednesday following a mysterious blast inside a school that left 17 students wounded.
An eye witness said that policemen arrived in Narbal village soon after the blast inside a school left 17 students injured.
However, youth pelted them with stones as they were heading towards the school.
The policemen resorted to tear gas shelling to disperse the protesters, triggering further clashes.
He said that announcements were being made over the public address system of a mosque asking youth not to engage in stone-pelting.
The injured students were shifted to PHC Kakapora and district hospital Pulwama for treatment. Some injured were shifted to Srinagar for specialised treatment.
