Amsterdam, Netherlands (CNN) -- Two men arrested at Schiphol International Airport in the Netherlands are being held on suspicion of plotting a terrorist act, Dutch authorities said Tuesday.
They are Yemeni citizens who were en route to the Yemeni capital, Sanaa, from Chicago, Illinois, officials said.
They were arrested Monday morning and authorities continued to question them Tuesday, Dutch prosecutors told CNN.
A U.S. law enforcement source said Monday the men may have been trying to test U.S. airport security by putting bottles with electronic devices attached in checked baggage.
But two U.S. government officials Tuesday said an initial U.S. investigation into the men shows no evidence of terrorism and no indication the men even knew each other. CNN
