Five men from Cambridge, Banbury, Wolverhampton, Leicester and Stockport, and a woman from Banbury were detained by police earlier.
All six are being held at a police station in the West Midlands.
Police said the suspects, aged between 21 and 37, were detained under Section 41 of the Terrorism Act as part of a planned operation.
