Residents in a village near Uri, which lies outside India's border fence but remains on the Indian side of the Line of Control, said the road leading to their homes had only two or three bunkers before the Uri attack took place, but now has as many as 50, many of which extend underground.
The move comes amid increasingly war-like rhetoric between the two nuclear-armed rivals.
Last week, Khawaja Muhammad Asif, Pakistan's Defence Minister, warned that its tactical nuclear weapons were "not just showpieces". "If our safety is threatened, we will annihilate them," he said of India.
Ram Madhav, a senior leader of Indian Prime Minister Narendra Modi's BJP party, said India would no longer take "a tooth for a tooth" to avenge Pakistani aggression. "For one tooth, the complete jaw. Days of so-called strategic restraint are over," he said.
