Earlier this month, guerrillas threatened with dire consequences cell phone service providers in Sopore after an equipment purportedly installed by terrorists on Badami Bagh cell phone tower was removed.

The equipment had reportedly been installed to improve their communication system since the tower was located at a vantage point.
