The latest foiled bomb plot targeting an airliner is an indication that, while the device did not ultimately pose a threat, terrorists remain determined, U.S. Secretary of State Hilary Clinton said Tuesday.
"These terrorists keep trying ... to devise more perverse and terrible ways to kill innocent people, and it's a reminder as to why we have to remain vigilant at home and abroad in protecting our nation and in protecting friendly nations," she told reporters at a news conference in New Delhi.
The plot was thwarted two weeks, a source familiar with the operation said Tuesday. Saudi intelligence assets provided the tip, the source said.
