Hello TheBlackDalia and welcome to the forum.
Firstly, I'd dare say that your starting proportions will no doubt be envied by many a forum member. As such, you need to stop obsessing over your increase in weight. Even at 68kg, you still appear incredibly svelte.
As for the small rolls, that may have appeared, you can still eat carbs and achieve weight loss. Granted, the type and quantity of carbohydrate consumed can ultimately affect one's level of weight gain or loss, largely due to the amount of insulin needed to break down the sugars contained within. However, the heavier your diet is in the consumption of complex carbs (wholegrains, legumes and pulses), the more measured the secretion of insulin, as complex carbs don't create the same severe spike that occurs following consumption of simple carbs.
That's not to say simple carbs aren't useful, particularly immediately after exercise, since they're an incredibly convenient way to replenish depleted glycogen reserves (energy stored in the muscles). However, consumption of energy dense, simple sugars needs to be moderated in the hours after exercise, to prevent excess glucose in the blood being stored as fat.
Regardless of which diet and exercise regime you adhere towards, they're all based upon expending more calories than you consume. The key to each of their respective successes rests upon achieving the correct energy balance, allowing weight to be lost without placing the body into starvation.
Given your slender proportions (yes, they are), you have to be incredibly astute with your calorie reduction, thus, allowing your body to utilise what little excess fat you possess as energy. This may come as shock to you, but you may have to consume more calories than you currently do, in order to get down to 60kg.
To ascertain how many calories you need, based upon your current measurements (age/weight/height) and level of activity, if you've not already done so, research BMR/TDEE calculators. Upon obtaining both figures, you'll gain an idea of how many calories your body needs to function in its resting state (BMR) and how many calories needed to support your level of current activity (TDEE).
Since you currently weigh 68kg, the figures between the two will be slight, leaving you with a difference of 200-300 Kcal, for example, hence why I'd mentioned that you need to be astute when introducing a deficit. As your energy balance is very much borderline, don't restrict calories from consumption of food (intake), allow the excess expended through exercise to create the deficit, thus, allowing those additional 8kg to gradually disappear.
As stated by fatforge, since you'll be working within a very fine margin, progress will be slower than you may have the patience for. You may even find that as your level of fitness improves, you'll have to slightly increase calorie consumption (TDEE) to support your endeavour.
Rest assured, though, a slight increase in calorie consumption won't necessarily lead to an increase in body fat, largely due to the fact that improved cardiovascular fitness and increased muscle tone/mass places a higher calorie demand upon the body, thus, ensuring continued improvement.
