"Combing and sanitisation operation have resumed today to clear the entire area of the unit. It will take some more time. No one has been allowed inside so far," a senior army officer said.
The officer said two main building complexes where the gun-battle and hostage-like situation took place have been cleared and they are totally free from blinds (unexploded shells).
Most of the blinds blast on the spot and the area is being cleared inch by inch so it will take some time before the unit area is opened for normal operation and activity, he said.
"Operation is on to see whether there is presence of any other militant in the area. We cannot take chances," he said.
Huge number of blinds of various types have been found in and around the two complexes and other areas of the unit, which were left behind by slain terrorists.
The army launched combing, search and sanitisation operation using sniffer dogs, bomb disposal squads with technical teams armed with equipment after conclusion of the day-long gun-battle between troops and three heavily armed militants, who stormed at 166 artillery unit of Army at Nagrota on Tuesday.
Jammu was rocked by two terror attacks in which seven army personnel, including two Majors, were killed and eight other security-men, including a BSF DIG, were injured, before six heavily-armed terrorists were eliminated in separate fierce encounters.
