A powerful explosion on Monday shook a double storeyed building at the Air Base where two terrorists are still holed up as the operations intensified to flush them out.
As the operation against the terrorists entered the third day, NSG, IAF and Army officers said there was no collateral damage to the strategic Air Force assets.
"Till now, we have eliminated four terrorists and operation to eliminate two more terrorists, possibly is in the final stage of conduct," Inspector General NSG Maj General Dushant Singh told a press conference here.
Singh, who was flanked by Air officer commanding, Air commodore J S Damoon and Brigadier Anupinder Singh, said "the entire operation will continue till all the personnel, assets, structure are physically combed. So it is likely to take a long time."
"These terrorists are holed up in a double storeyed building which is a living accommodation of the Air Force personnel and currently the operations are in progress to clear this building from the terrorists," Brigadier Singh said.
Prime Minister Narendra Modi, meanwhile, presided over a high-level meeting to discuss the ongoing operation at Pathankot air base to flush out holed up terrorists and the attack on Indian consulate in Afghanistan.
