Photometric follow-ups of transiting exoplanets may lead to discoveries of additional, less massive bodies in extrasolar systems. This is possible by detecting and then analyzing variations in transit timing of transiting exoplanets. In 2009 we launched an international observing campaign to detect and characterize transit timing variation signal in selected transiting exoplanets. The programme is realised by collecting data from 0.6 - 2.2-m telescopes spread worldwide at different longitudes. We present our observing strategy and summarize first results for selected transiting exoplanets.
