American funds and Israeli terrorism

"American investigators, cooperating in a probe of the January assassination of a top Palestinian leader in Dubai, have identified a handful of U.S.-based companies believed to have been used to transfer money to suspects in the case, a finding that brings international authorities closer to identifying who funded the operation.
The findings show American authorities playing a bigger role in the investigation than previously revealed. The case is especially delicate for the U.S., because Dubai police have said their prime suspect in the case is Mossad, the intelligence service of Israel, a key U.S. ally." (thanks Sus)
