German intelligence is warning of a new breed of terrorist - whole family groups travelling to training camps on the Afghan-Pakistan border where they learn how to use explosives and raise funds.
Parents travelling with children have in the past raised less suspicion than single men or women travelling to and from Germany.
Now officials have the names of 100 suspects they believe may be radicalised and ready to strike.
Germany is braced for a terror attack after repeated threats because of its involvement in Afghanistan.
Authorities say the new breed of terrorist - including Germans who have converted to Islam - even travel with babies to the 'bandit country' of Waziristan.
