‘Act Of Terrorism’ Was ‘Heinous And Cowardly,’ Obama Says
by Mark Memmott
Boston Explosions Update at 12:40 p.m. ET. Where Things Stand. DEATHS, INJURIES: Three people were killed and at least 176 were injured, according to Boston Police. At least 17 of the wounded were critically injured.
INVESTIGATION: Authorities searched an apartment in the Boston suburb of Revere late Monday. They left with some bags. There have been no arrests reported and officials aren't commenting on whether anyone is or isn't in custody. A doctor who treated victims says an X-ray indicated that BBs or ball bearings may have been packed into the explosives. Massachusetts Gov. Deval Patrick (D) said that all parcels left at the scene have now been examined and no additional bombs were found. The AP and CBS are reporting they've been told by informed sources that "pressure cooker bombs" were used.
President Obama told reporters that it's clear this was an "act of terrorism," but that it's not known yet whether it was the act of an individual or a group, and whether it was foreign- or domestic-related.
SECURITY: As Boston and other major cities across the nation and around the world keep their police on alert, there's particular concern in London — which hosts former Prime Minister Margaret Thatcher's funeral on Wednesday and a major marathon next Sunday. "British officials on Tuesday urged a review of security measures," The New York Times says. Meanwhile, FBI Special Agent in Charge Rick DesLauriers said Tuesday that there are "no additional threats" in Boston.
Update at 12:40 p.m. ET. "Pressure Cooker" Bombs?
A "person briefed on the probe" tells The Associated Press that the bombs were "pressure cookers with metal [and] ball bearings" packed inside. It isn't know yet what was used to set off the explosions, the AP reports.
CBS says that "A law enforcement source told CBS News that one of the explosive devices appears to have been placed in a metal pressure cooker (a metal kitchen pot with a locked down top) which had been placed in a black nylon bag or backpack. Investigators also found pieces of an electronic circuit board possibly indicating a timer was used in the detonation of the bomb.
"A law enforcement official told CBS News that the two bombs that exploded were made to look like discarded property. It is still unknown if one or both bombs were in garbage cans. One may have been on the sidewalk."
According to a 2004 Department of Homeland Security memo, "these bombs are made by placing TNT or other explosives in a pressure cooker and attaching a blasting cap at the top of the pressure cooker."
NPR has not independently confirmed that authorities suspect pressure cooker bombs were used.
As we said when the day began: We will focus on news being reported by NPR, other news outlets with expertise and statements from authorities in position to know what's going on. And if some of that information turns out to be wrong, we'll update.
Update at 11:35 a.m. ET. This "Act Of Terrorism" Was "Heinous And Cowardly," Obama Says:
Speaking at the White House, the president just said that "given what we now know about what took place, the FBI is investigating it as an act of terrorism." What isn't known, he said, is whether it was the act of an individual or a group, and whether it was foreign- or domestic-related.
The way people at the marathon responded and helped each other, the president added, shows that "the American people refuse to be terrorized" even by such a "heinous and cowardly act."

"But Dr. Stephen Epstein of the emergency medicine department at Beth Israel Deaconess Medical Center said he saw an X-ray of one victim's leg that had 'what appears to be small, uniform, round objects throughout it — similar in the appearance to BBs.' He said it remained to be determined what exactly the objects were."
