A couple have been arrested on suspicion of Syria-related terrorism offences at Heathrow Airport.
The man, 20, and woman,19, from Walsall, were detained at around 10.30 on Tuesday night as they disembarked a flight from Istanbul, Turkey, police said.
They were held by officers from the West Midlands Counter Terrorism Unit.
Police said there was no risk to the safety of the flight and described the arrests as "planned and intelligence led".
Two addresses in Walsall are being searched and the suspects are in custody in the West Midlands.
The arrests come less than a week after a 19-year-old man from Coventry was held by counter-terrorism officers at the same airport after arriving on a flight from Jordan.
