"A low intensity blast took place by the roadside near the Mini Secretariat in Shopian around 11.20 AM but there was no harm done," a police official said.
He said forensic experts have been rushed to the spot for collecting the samples to ascertain the nature of the explosive substance.
Chief Minister Mufti Mohammad Sayeed was scheduled to attend a function in Shopian today but it was cancelled due to a strike call given by traders' bodies.
He said Sayeed was scheduled to leave for Shopian "very early in the morning", several hours before the incident took place.
The official said Sayeed's visit was called off following a strike call given by traders' bodies.
