We report on the observation of ultralong range interactions in a gas of coldRubidium Rydberg atoms. The van-der-Waals interaction between a pair of Rydbergatoms separated as far as 100,000 Bohr radii features two important effects:Spectral broadening of the resonance lines and suppression of excitation withincreasing density. The density dependence of these effects is investigated indetail for the S- and P- Rydberg states with main quantum numbers n ~ 60 and n~ 80 excited by narrow-band continuous-wave laser light. The density-dependentsuppression of excitation can be interpreted as the onset of aninteraction-induced local blockade
