Here is the blog post that started the reports.
At the invitation of Hariri-Saudi group, Hitchens is visiting Lebanon. A source sent me this: “I dont know if you find this as news worthy or not, but Christopher Hitchens is currently in Beirut sponsored by the same group that owns that crap NOW Lebanon. He got in a few nights ago and surprisingly went out drinking. On his way out of the bar he saw an SSNP poster and wrote on it “F___ the SSNP”. There just happened to be some SSNP thugs near by–most likely asking people for their ID, and most likely to no avail–and saw him write on the poster and kicked his ass. He is still walking with a limp.”
