The two guys at michelle's apt.
I believe these guys who we see later in the parking garage and in the end are obviously Israeli Mossad agents.
The Arab in the club with the American Express blames 'those Israeli dogs' for the killing of his colleage in the Peugeot.
Also in the end those two don't seem to be bothered so much about the device being lost in the river- as if saying as long as the Arabs don't put their hands on it who cares.
What do you think?
