Kenyan police say they have arrested two Germans and a Dutch national on suspicion of terrorist activities.

Police spokesman Eric Kiraithe says the three were arrested at Nairobi's international airport late Thursday as they attempted to leave the country.

The three have been identified as Germans Andrej Hermlin and Gerd Uwe, along with a Dutch woman, Fleur van Dissel.

Kiraithe says the suspects entered the country as journalists but have "been conducting themselves in a suspicious manner."  He says the three took video footage of security installations in the country.

The spokesman says police are still investigating the incident.
