KEY POINTS:
Three men suspected of planning attacks at Frankfurt airport and a US military base in Ramstein have been arrested, a German broadcasting network said yesterday.
Two of the suspects were German nationals and one had a Pakistani passport.
Germany, which has forces stationed in Afghanistan, has been on high alert for attacks. The country has feared a re-emergence of militant Islamic groups since 2001, when the northern port city of Hamburg was used as a base for the September 11 attacks.
