West Midlands police said Tuesday that the suspects' homes are being searched and they are being questioned.
Police say one 45-year-old is suspected of attending a terrorist training camp.
The others are being questioned on suspicion of facilitating terrorism overseas.
The suspects include a 44-year-old woman, her 20-year-old son, and a 36-year-old man.
