In mid July 2001, some of the hijackers and members of the Hamburg cell gathered near
Salou,
Spain, for a period of a few days up to a couple of weeks. There seemed to be tension between Jarrah and Atta about the plot in its late stages. Atta had complained to Binalshibh about his difficulty in getting through to Jarrah and his fear that Jarrah might withdraw from the plot completely.
