Boston Marathon explosions latest: FBI raids flat in city's suburbs as bombs are revealed to be packed with ball bearings

Various security agencies have raided a flat in a Boston suburb. Officers from the FBI, the Department of Homeland Security and US Immigration and Customs Enforcement searched the fifth floor flat in Revere, five miles from the site of the blast.
They were then seen leaving the property with a brown paper bag.
Two unexploded devices recovered near the attack will be analysed today, including one reportedly found around the corner from the first blasts. A third device was reportedly destroyed in a controlled explosion.
The overnight death toll after the Boston marathon bombing had risen to three this morning as federal and local investigators swarmed the city to try to hunt down those responsible for a pair of explosions that also caused injuries to at least 140 other people, at least 17 of whom remain in a critical condition.
As news emerged that one of the dead was an eight-year-old child, doctors from area hospitals began to report that many of those admitted had suffered from shrapnel injuries. The devices had been packed with ball bearings, according to reports, to cause maximum injuries. Hospitals also confirmed that numerous patients suffered lower limb injuries including some who had undergone amputations.
"These runners just finished and they don't have legs now," Roupen Bastajian, 35, a Rhode Island state trooper and a former Marine was cited as saying in the New York Times. "So many of them. There are so many people without legs. It's all blood. There's blood everywhere. You got bones, fragments. It's disgusting."  A runner in the race himself, he added:  "We put tourniquets on. I tied at least five, six legs with tourniquets."
The horror delivered a cold shock to the entire country as evidence mounted that this was a terrorist attack even if it remained unclear if it might be traced to a domestic group or individual or to an international terror cell like al-Qa'ida.  Some analysts noted that Monday marked the start of a week that includes Patriot Day an important date to anti-government groups.  The US is also coming up on the 19th April anniversary of the attack on the federal offices in Oklahoma City.
There was a sense of curfew in Boston as the FBI and local police sealed streets and scrambled to investigate. "We don't yet have some of the answers," President Barack Obama said. The word "terror" did not leave his lips. "We still don't know who did this or why...but make no mistake we will get to the bottom of this and we will find who did this and we will find out why they did this," he said, adding that the guilty "will feel the full weight of justice".
