BOSTON, MA (KTVI) – Two simultaneous explosions are reported near the finish line at the Boston Marathon at around 2:50pm on Monday. The explosions sent smoke billowing into the air at Copley Square, turning a site of celebration into a mess of destruction. They were  were about 50-100 yards apart. The explosions happened after the first runners had crossed the finish line. Many runners were still finishing the race.

According to CNN federal authorities are classifying Monday’s bombings at the Boston Marathon as a terrorist attack, but it’s not clear whether its origin was domestic or foreign, a federal law enforcement official with knowledge of the investigation said.

Boston police say that there is no suspect in custody. Anyone with information should call – 1-800-494-TIPS. Call 1-617-635-4500 for a victim hotline.

The number of wounded treated at Boston hospitals after Monday’s Boston Marathon bombings has risen to 140, including 17 in critical condition, hospital officials said. Three people died in the terror attack, including an 8-year-old boy, a state law enforcement source said. A terrorism expert with CNN says there have been ten lost limbs from the explosions.  Doctors are picking ball bearings out of victims in the emergency room.

The Lenox Hotel was evacuated, the Boston Globe reported, as authorities looked into possible security concerns. Bomb sniffing dogs are searching the area. Two more explosive devices have been found.

The Boston Police Commissioner gave a press conference at around 3:50pm on Monday.  He says all victims have been removed from scene.  They immediately enacted special system with FBI & State Police.

All bags, purses and backpacks are being checked for explosives. Many runners dropped bags when they fled scene.

It is also Patriots’ Day in Boston. The marathon is held every year on this day. Many businesses not full because of holiday. The marathon was being run in honor of the Newtown shooting victims.

The marathon takes several hours for all runners to cross. There are more than 26,000 runners participate in this race. The marathon stopped after the explosions.

Other cities, including New York and Washington, tightened security as a result. Following standard protocol, the White House cleared out an area in front of the West Wing. St. Louis Police Chief Sam Dotson says that no security changes have been made in St. Louis, MO.

St. Louis Marathon President Nancy Lieberman released this statement about the events in Boston on Monday, “We are deeply saddened by the tragic events at today’s Boston Marathon, a world-class event that showcases sportsmanship and athleticism.
