A silver Mercedes packed with canisters of gas and nails and apparently rigged to explode was discovered in London's bustling nightclub and theater district early Friday morning, British police said, and could have caused "significant injury or loss of life" if it had been detonated.
Police defused the bomb and launched a massive investigation into what security officials said was presumed to be an attempted terror attack. The probe will include reviewing huge amounts of footage from the closed-circuit cameras that ring the Haymarket area, close to Piccadilly Circus and Trafalgar Square.
The facts recounted in the article give the impression that the bomb failed to go off as it was supposed to, but whether that's in fact the case is unclear. Regardless, this is a worrisome development.
