The Netherlands and Nigeria will begin using body scanners on airline passengers following the attempted terrorist attack on a U.S.-bound flight on Christmas Day, authorities in both nations said Wednesday.

The millimeter-wave body scanners will be in place at Amsterdam’s Schiphol Airport in about three weeks and will be used on all passengers traveling to the United States, Dutch Interior Minister Guusje ter Horst told a news conference at The Hague.

“We’ve escaped a very serious attack with serious consequences, but unfortunately in this world there are individuals who do not shy away from attacks on innocent people,” she said.

Nigeria did not say when it would begin the new scans. “In combating the new threat of terrorism as unfolded recently, Nigeria will be upgrading its security screening system to 3D Total Body Imaging Scanner,” the country’s airport authority said in a statement. It gave no further details.
