I'm not in a position to say authoritatively that this was carried out by Lashkar-e-Jhangvi. They were a pretty seriously weakened organization when I was there (in Pakistan), so it could have been a consortium. But I don't think it was a consortium that was put together in this country.
In my relatively limited time here virtually every significant attack I'm aware of, where I've got some information, either came out of the tribal areas out of Pakistan or Baluchistan. I don't have any details on this one, but there does indeed seem to be a pattern.
