The clades of R1a1 seen in Saudi Arabia are Indo-Iranian specific and actually span the full spectrum of Indo-Iranian specific clades, meaning large scale migration into Arabia from Iran/India.
These include the specific tribe that is the keeper of the "holy mosque" at mecca: the name of the tribe I cannot remember.
Within the Kurds are found entire clades equivalent to the european-specific clades, and this is a good indicator of the diversity to be found further east from where the Kurds are to have migrated. Equivalent clades have also been found in India.
The C Asiatic clades including Tarim and Andronovo are India-specific.
What is seen is the wave model of R1a1 expansion: 1st was European-specific expanding out of the ME (probably Iran), with a 2nd wave trailing the the 1st which was more Asiatic-specific with percolations also into Europe..
