During INTEGRAL deep observations of the Galactic Plane in the region of the Crux spiral arm a new outburst of the accreting X-ray pulsar IGR J11435-6109 (ATEL #350, #358, #359, #362, #370, #377) was detected. The source brightness in the energy band 17-60 keV gradually increased from <0.5mCrab on June 2-10, 2005 up to ~15 mCrab on June 20-21, 2005. Observations in all wavelengths are encouraged.
