Hello.
I'm engaged and we want to get married in his city but I wanna know how the security conditions are .
Peshawar is the city and if you could guide me will be awesome 
I understand you may be interested in the crime rate, and possibly wanting information regarding the chances of terrorist activity in that area.
The sad terrorist attack on the school there proves there is extremist activity in the region, but a few fools don't mean the place is generally unsafe.
This site suggests general crime is low.
This US site tells you it's extremely dangerous, but they have special reasons for concern that don't apply to most other people.
A local site is telling us of tensions between residents and displaced groups, along with violent, armed crime.
Overall, it sound like they're having some problems out there, but that's reports, and they aren't always accurate.
Let's hope local knowledge from people on the ground gets posted.
