You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

Sent 2: Soon after moving to Hamburg, Essabar met Binalshibh and the others through a Turkish mosque.
Sent 3: Essabar turned extremist fairly suddenly, probably in 1999, and reportedly pressured one acquaintance with physical force to become more religious, grow a beard, and compel his wife to convert to Islam.
Sent 4: Essabar's parents were said to have made repeated but unsuccessful efforts to sway him from this lifestyle.
Sent 5: Shortly before the 9/11 attacks, he would travel to Afghanistan to communicate the date for the attacks to the al Qaeda leadership.
Sent 6: Mounir el Motassadeq, another Moroccan, came to Germany in 1993, moving to Hamburg two years later to study electrical engineering at theTechnical University.
Sent 7: A witness has recalled Motassadeq saying that he would kill his entire family if his religious beliefs demanded it.
Sent 8: One of Motassadeq's roommates recalls him referring to Hitler as a "good man" and organizing film sessions that included speeches by Bin Ladin.
Sent 9: Motassadeq would help conceal the Hamburg group's trip to Afghanistan in late 1999.
Sent 10: Abdelghani Mzoudi, also a Moroccan, arrived in Germany in the summer of 1993, after completing university courses in physics and chemistry.
Sent 11: Mzoudi studied in Dortmund, Bochum, and Muenster before moving to Hamburg in 1995.
Sent 12: Mzoudi described himself as a weak Muslim when he was home in Morocco, but much more devout when he was back in Hamburg.
Sent 13: In April 1996, Mzoudi and Motassadeq witnessed the execution of Atta's will.
Sent 14: During the course of 1999, Atta and his group became ever more extreme and secretive, speaking only in Arabic to conceal the content of their conversations.
Sent 15: 87 When the four core members of the Hamburg cell left Germany to journey to Afghanistan late that year, it seems unlikely that they already knew about the planes operation; no evidence connects them to al Qaeda before that time.
Sent 16: Witnesses have attested, however, that their pronouncements reflected ample predisposition toward taking some action against the United States.
Sent 17: In short, they fit the bill for Bin Ladin, Atef, and KSM.
Sent 18: Going to Afghanistan The available evidence indicates that in 1999, Atta, Binalshibh, Shehhi, and Jarrah decided to fight in Chechnya against the Russians. 
Question: In what country did Essabar and Binalshibh meet?.
