Very sorry to hear about the lady. We were in Tunisia at the time and didnt know anything but was told about it on our return.
We live in Bolton and in the past week there have been 5 stabbings. It terrifies me when my niece whom i adopted at 6 and is now 18 tells me she is going into town here clubbing.
BUT i feel Tunisia is so safe we have been going a couple of times each year for the past 6 years, and last year i allowed my niece to go on her own (with a friend but not me) as i feel it is so safe.
When we are there we have so many tunisian friends both my niece 18 and my nephew 12 go out places with them, and i just stay at hotel.
Tunisia i feel is a very safe place but like any where just be alert as not everyone is perfect.
