  The soft X-ray and soft gamma observations of the new discovered TeV sources
by HESS and MAGIC are crucial to discriminate between various emitting
scenarios and to fully understand their nature. The INTEGRAL Observatory has
regularly observed the entire galactic plane during the first 1000 day in orbit
providing a survey in the 20-100 keV range resulted in a soft gamma-ray sky
populated with more than 200 sources. In the case of HESS J1813-178 INTEGRAL
found the hard X-ray counterpart IGR J18135-1751 and Swift/XRT Telescope
performed follow-up observations on this source. Here we present the soft/hard
X-ray spectral study. We reported on the INTEGRAL observation of LS 5039, the
first microquasar that have been observed by HESS up to now.
