Two blasts rocked the centre of Stockholm on Saturday in a possible attack inspired by Sweden's presence in Afghanistan, killing the bomber and wounding two other people, police and media said. Swedish news agency TT said that 10 minutes before the first blast, when a car exploded near a busy shopping street, it received an email with threats over the Swedish presence in Afghanistan and over a years-old case of caricatures of the Prophet Mohammad by a Swedish artist.
