Corrected entry: (Spoilers.) On the ship, Samir pretends to feel ill and is being escorted by the terrorist group's head of security. Samir asks him how many men he has protecting the group's leader, and the security guy replies with a number (can't remember how many). Yet when Samir returns to gun down the terrorist leader, absolutely no security people show up.
Corrected entry: While the marks (the people that are to bomb the bus) are shown boarding the bus, there is a mistake. The plot later reveals that all of the bombers were on the same bus. However, while they board, at least two different bus drivers are shown accepting their tickets. One is an older man and the other is probably a woman with reddish hair (the woman is shown first).
