"Four civilians have sustained injuries due to an explosion at the encounter site," Superintendent of Police, Shopian, Altaf Khan told PTI.
Khan said the operation, in which two militants were killed and four army personnel, including a major, injured, concluded late last night.
"We concluded the operation last night but had made announcement in a local mosque asking people not to go near the encounter site till the bomb disposal squad gave a green signal. However, this morning, few people went near the site and four of them were injured due to the explosion," he said.
As the joint team of police and army began a search operation in the area, the hiding militants opened fire on them triggering an encounter.
The gunfight was halted for the night on Tuesday and resumed yesterday morning and during the gunfire, the militants were gunned down.
