Terror plot thwarted as US-bound explosives seized

Authorities on three continents thwarted multiple terrorist attacks aimed at the United States from Yemen on Friday, seizing two explosive packages addressed to Chicago-area synagogues and packed aboard cargo jets. The plot triggered worldwide fears that al-Qaida was launching a major new terror campaign.

In the U.S., cargo planes were searched up and down the Eastern Seaboard, and an Emirates Airlines passenger jet was escorted down the coast to New York by American fighter jets. No explosives were found aboard those planes, though the investigation was continuing on at least two.

Since the failed Christmas bombing of a Detroit-bound airliner, Yemen has been a focus for U.S. counterterrorism officials. Before that attack, the U.S. regarded al-Qaida’s branch in Yemen as primarily a threat in the region, not to the United States.
