  Thanks to INTEGRAL's long exposures of the Galactic Plane, the two brightest
Soft Gamma-Ray Repeaters, SGR 1806-20 and SGR 1900+14, have been monitored and
studied in detail for the first time at hard-X/soft-gamma rays. SGR 1806-20,
lying close to the Galactic Centre, and being very active in the past two
years, has provided a wealth of new INTEGRAL results, which we will summarise
here: more than 300 short bursts have been observed from this source and their
characteristics have been studied with unprecedented sensitivity in the 15-200
keV range. A hardness-intensity anticorrelation within the bursts has been
discovered and the overall Number-Intensity distribution of the bursts has been
determined. The increase of its bursting activity eventually led to the
December 2004 Giant Flare for which a possible soft gamma-ray (>80 keV) early
afterglow has been detected with INTEGRAL. The deep observations allowed us to
discover the persistent emission in hard X-rays (20-150 keV) from 1806-20 and
1900+14, the latter being in quiescent state, and to directly compare the
spectral characteristics of all Magnetars (two SGRs and three Anomalous X-ray
Pulsars) detected with INTEGRAL.
