On May 3, 1999, India learned about an intrusion by Pakistani troops in the Kargil-Dras sector in Jammu and Kashmir. Three weeks later, a counter-offensive, code-named Operation Vijay, was launched. However, the Indian defence forces, dealing with outdated military and technical equipment, found it hard to locate and attack Pakistani soldiers hiding in bunkers in strategic locations.
India called for help. But New Delhi was facing a technological, economic and arms embargo by countries, led by the US, for its nuclear weapons test in 1998. Israel, despite being an ally of the US, helped India with mortars and ammunition, even providing the Indian Air Force with laser-guided missiles for its Mirage 2000H fighter jets.
