AMSTERDAM – Dutch prosecutors say two Yemeni citizens who arrived in Amsterdam on a flight from the United States are suspects in a conspiracy to commit a terrorist act.
Prosecutors said the two men flew in from Chicago on Monday and were bound for Sana'a, the Yemeni capital. They were detained due to information provided by U.S. authorities.
Their luggage was sent on an internal flight to Washington, where U.S. authorities found suspicious items. But Dutch authorities said nothing suspicious was in the luggage that arrived in Amsterdam.
Prosecutors said Tuesday the men were being held "on suspicion of a conspiracy to a terrorist criminal act." It will be announced in a few days if they will be charged.

WASHINGTON (AP) — Two men arrested in Amsterdam may have been conducting a dry run for a potential terrorist attack, U.S. officials said Tuesday after a cell phone taped to a Pepto-Bismol bottle and a knife and box cutters were found in one of the men's luggage.
U.S. investigators are pursuing leads in Detroit, Birmingham, Ala.; and Memphis, Tenn., according to officials speaking on condition of anonymity to discuss the ongoing investigation.
The arrests come at a time of heightened alert just days before the ninth anniversary of the Sept. 11, 2001 terror attacks.
On Sunday, authorities found the suspicious items — a cell phone taped to a Pepto-Bismol bottle, multiple cell phones and watches taped together, and a knife and box cutter — in one of the men's checked luggage in Virginia. The man and his luggage were headed to separate international destinations, which also raised concerns.
None of the items found on the men or in their luggage violated U.S. security rules. But the items and the men's changing travel itinerary may have been a deliberate test of the U.S. aviation security system to determine what would raise red flags.
Neither man were on any U.S. terror watch lists, White House spokesman Robert Gibbs told CNN Tuesday.
A U.S. law enforcement official identified the men as Ahmed Mohamed Nasser al Soofi and Hezam al Murisi. Al Soofi is of Yemeni descent from the Detroit area, one of the law enforcement officials said. An Alabama official said he had been living in Tuscaloosa for a time.
The pair were arrested Monday morning at Schiphol Airport after getting off a United Airlines flight from Chicago.
RTL Television News broadcast video footage filmed on a passenger's cell phone of armed law enforcement officers escorting two men off the plane, their hands bound behind their backs. The officers' weapons were holstered and there appeared to be no resistance.
They were being held at the Amsterdam airport for questioning, but neither has been charged with any offense in the Netherlands, said Martijn Boelhouwer, spokesman for the national prosecutor's office. Under Dutch law, the men can be held without charges for up to six days. No charges have been filed against the men in the U.S., a law enforcement official said.
Al Soofi was questioned as he went through security in Birmingham, Ala., on his way to Chicago, one of the officials said. He told the Transportation Security Administration authorities he was carrying a lot of cash. Screeners found $7,000 on him, but he was not breaking any law by carrying that much money.
Al Soofi was supposed to fly from Chicago to Washington Dulles International Airport in Virginia and then on to Dubai, one of the officials said. But when he got to Chicago, he changed his travel plans to take a direct flight to Amsterdam, while his luggage went on to Virginia.
On international flights, passengers and their luggage must be headed toward the same destination, according to U.S. policy.
Al Murisi also changed his travel plans in Chicago to take a direct flight to Amsterdam, raising suspicion among U.S. officials. Federal Air marshals were on the flight from Chicago to Amsterdam, a law enforcement official said.
Homeland Security spokeswoman Amy Kudwa said once officials found suspicious items in luggage associated with two passengers on Sunday night's flight, they notified the Dutch authorities.
Alabama's director of homeland security, Jim Walker, said al Soofi had been living in Tuscaloosa, Ala., and working at a convenience store for about the last three months. He said there was nothing that al Soofi had done in Alabama that brought him to the attention of Alabama officials.
Security at Amsterdam's main airport has been boosted this year, after Umar Farouk Abdulmutallab, a Nigerian student, flew from Schiphol airport to Detroit on Christmas Day with explosives in his underwear. Abdulmutallab allegedly tried to detonate the explosives over the United States before being grabbed by passengers and crew.
After the Abdulmutallab security lapse, Schiphol ordered 60 new full body scanners to screen passengers flying to the United States. Those who do not pass through the scanners are patted down.
American passengers arriving from the United States on Tuesday appeared to take the news of the arrests in stride.
"There is always going to be problems but I think that the system in terms of security works pretty well. I am traveling all the time and I feel pretty safe," Steve Harriot of Chicago told AP Television News.
"I think we have to be vigilant, all of us. It is not going to change my travel," Francois Binette of San Francisco said.
