US wants tighter security on US bound flights

The U.S. is calling for tighter security at some foreign airports.

Apparently this had been prompted by concerns that al-Qaida could create a bomb that could go undetected through airport security. The announcement was made on Wednesday by the Homeland Security Department. No specifics have been released about the threat, but US news reports quote anonymous American intelligence officials as saying that there are indications that bomb makers from al-Qaida's Yemen and Syria affiliates are working to perfect an explosive device. Which airports have been asked to tighten security is also not clear, but there are more than 250 foreign airports that offer nonstop flights to the U.S. mainland, including Paris' Charles de Gaulle Airport and Amsterdam's Schiphol Airport.
