AMSTERDAM (Reuters) - Dutch police conducted security searches around Amsterdam's Schiphol airport on Saturday in response to "indications" of a threat, an official said, causing traffic jams during the busy summer holiday season. The National Coordinator for Counter-terrorism and Security Policy (NCTV) provided no details of the possible threat, but it said extra security measures were implemented, including vehicle searches. "There was a (threat) indication related to the airport," said spokesman Edmond Messchaert.
