Authorities arrested Steven N., 26, Abdullah W., 28, and Abdulsalam W., 23., all German nationals, at Hamburg airport on Sept. 6 on suspicion of membership in Shabaab; they had just arrived from Mombasa in Kenya. Two more Islamist terror suspects were arrested in Simbach am Inn while on their way to Syria; and two German Islamists suspected of Shabaab membership were recently arrested in Kenya.
