MENDHAR: At least four landmines exploded due to a forest fire along the Line of Control (LoC) in Jammu and Kashmir's Poonch district on Sunday, but there was no casualty, officials said.

The fire broke out in Lanjote forest in Balakote sector of Mendhar sub-division around 1 pm and set off the landmines, they said.
