An unused cartridge of the army exploded accidentally killing a seven year-old boy and injuring eight others in Assam's Baksa district on Sunday.
The children had collected unused cartridges from the army's Sukanjuli test firing range on the Indo-Bhutan border to sell them in the local market when one of them exploded, police said.
While the boy died on the spot due to the blast, the injured were rushed to the civil hospital here, the police said.
Locals collect unused cartridges from near the test firing range and sell them in the local market as there is demand for the copper in them.
