Washington, Jumada II 6, 1434, Apr 16, 2013, SPA - Two bombs exploded near the finish line of the Boston Marathon Monday, killing two people and injuring over 100, authorities said. A senior U.S. official said two other bombs were found near the end of the 42-kilometer course. President Barack Obama told reporters at the White House that those responsible will "feel the full weight of justice." The blasts took place almost simultaneously about 91 meters apart, shattering windows and sending smoke into the air. Boston police said that two people were killed, while area hospitals reported at least 105 injured, at least 15 of them critically. Roughly 23,000 runners took part in the Boston Marathon, one of the world's oldest and most prestigious marathons. The Federal Aviation Administration (FAA) barred low-flying aircraft from within 5.6 kilometers of the blast site. Obama told Boston Mayor Tom Menino and Massachusetts Governor Deval Patrick that his administration would provide whatever support was needed. --SPA 10:56 LOCAL TIME 07:56 GMT www.spa.gov.sa/1099212
