I have travelled with Army convoy from Srinagar to Jammu, and vice versa several time, and the region near the Anantnaag,which the local Kashmiri also called Islamabad, is the Most dangerous place in NH1 road, which is the life line of the valley and the order for the convoy is not to stop in that region what so ever. To Militant uses riffle fired grenade on the convoy, specially in Military Buses, carrying Jawans and their families, toward the window glasses, so that it maximizes the effect. The Area where this incidence happens is near Anantnaag which is around 20-25 KM of dangerous area, because its Populus building along the roads. After this place, the plains ended and mountains started an uphill slow road till Jawahar Tunnel.
