Obviously there are many, many reports available online about the terror attack in Boston yesterday. The information remains fluid. Here is just one current report from Fox News.
“Source close to the investigation tells Fox News that ‘pressure cookers were used’ in both bombs — possibly as timers — that exploded yesterday at the Boston Marathon finish line, killing 3 and wounding 176. Another source says the style of device closely resembles that commonly seen in Afghanistan and Pakistan.”
