I see nothing alive in the pots. (Maybe it's just the photos.) Judging from the light color of the peat pots, the soil is way too dry. If the seeds swelled and began to sprout some days ago, then they are likely dead at this point. If that's the case, then you'll need to re-seed, and keep the soil moist enough (from bottom watering) to show a dark color in the margins of the peat pots.
If they never did anything, then just water and warmth may germinate what's already there. I would be inclined to re-seed regardless.
The germination soil can be soggy for the first couple of days, then should be kept damp, to prevent the fragile seedlings from desiccating.
My experience in the past led me away from using peat pots at all, since they make regulation of the moisture difficult, and the roots of tobacco seedlings never seem able to penetrate the peat, even after transplanting to the ground. I would have to peel away the peat prior to transplant.
