Shrike

During my trip to Uzbekistan in September 2002 I observed and photographed a mystery shrike near Bukhara city in that country. In that area I saw many Turkestan Shrike and Long-tailed Shrike, but this bird was different. The bird was seen for a very short time - ca 10'. I maked only these two photos.
In my opinion, this bird is a probably Brown Shrike, but I don't find any information in bibligraphy about records of Brown Shrike in Uzbekistan.

I will be very grateful for your opinion and help with the identification of this shrike and information about its occurrence from that region.
