Obama to honor Boston bombing victims
WASHINGTON (AP) — President Barack Obama is seeking to refocus a nervous nation's attention on those killed and gravely wounded in what he called an "act of terror" at the Boston Marathon.
Americans also will be looking to the president to offer reassurances about the nation's safety as investigators scramble to answer key questions about an attack with origins that are yet unknown.
The president was to speak Thursday at an interfaith service in Boston honoring the three people killed and 170 injured when a pair of bombs ripped through the crowd gathered Monday afternoon near the finish line of the famous race. Investigators have an image of a potential suspect, though much about what happened remains a mystery, keeping tensions high in Boston and elsewhere around the country.
Compounding the nation's jitters were letters sent to Washington officials that contained suspicious substances, including ones addressed to Obama and Sen. Roger Wicker, R-Miss., that showed traces of poisonous ricin in initial tests. The letters evoked eerie parallels to the anthrax attacks that followed the terrorist attacks of Sept. 11, 2001.
