INTEGRAL observations taken on 2016 August 23 between MJD 57623.26 and
57623.84 clearly confirm the highly absorbed super-giant high mass
X-ray binary pulsar EXO 1722-363 (IGR J17252-3616) to be the source
reported as flaring in ATel #9412 by MAXI.
The source flux in individual INTEGRAL raster pointings varies
strongly from below 5 mCrab up to a maximum of 60 mCrab (20 - 40 keV;
assuming a count rate of 165 cts/sec for 1 Crab). This source behavior
is comparable to the activity seen in the past with INTEGRAL (e.g.,
Kuulkers et al. 2007, A&A 466, 595 and Zurita-Heras et al. 2006, A&A
448, 261
