Yes this is not safe to visit beyond Benihal tunnel. Patnitop is the last place where you can go comparatively safe. After that this is valley and you never know, even security people stay at alert all the time.
but recently i did not hear anything like terrorist attacks there may be now there is peace. My younger brother is going to Amarnath this month and have planned to go Srinagar let him come and see what he says. :)
Because no outsider are going, They have driven out even workforce from other parts of the country. Now this is in between Security forces and terrorist groups, not published much. I had been there for years.
