  A number of new X-ray sources (IGR J17091-3624, IGR/XTE J17391-3021, IGR
J17464-3213 (= XTE J17464-3213 = H 1743-322), IGR J17597-2201, SAX/IGR
J18027-2017) have been observed with the INTEGRAL observatory during ultra deep
exposure of the Galactic Center region in August-September 2003. Most of them
were permanently visible by the INTEGRAL at energies higher than $\sim 20$ keV,
but IGR/XTE J17391-3021 was observed only during its flaring activity with a
flux maximum of $\sim120$ mCrab. IGR J17091-3624, IGR J17464-3213 and IGR
J17597-2201 were detected up to $\sim 100$-150 keV. In this paper we present
the analysis of INTEGRAL observations of these sources to determine the nature
of these objects. We conclude that all of them have a galactic origin. Two
sources are black hole candidates (IGR J17091-3624 and IGR J17464-3213), one is
an LMXB neutron star binary (presumably an X-ray burster) and two other sources
(IGR J17597-2201 and SAX/IGR J18027-2017) are neutron stars in high mass
binaries; one of them (SAX/IGR J18027-2017) is an accreting X-ray pulsar.
