[Original Story] Two explosions rocked the Boston Marathon as runners were crossing the finish line at about 3:00 pm Eastern Daylight Time. No official numbers on how many are injured.  WBZ estimates about 20 at the first site, but are unsure of the second location. No deaths reported.

The explosions were only seconds apart, the first happening right at the finish line of the Boston Marathon near Copley Square, the second further up the street as runners we passing by.

According to WBZ-TV reporters and producers on the scene, it is believed the explosion at the finish line came from within a sports apparel shop and blew out towards the crowds along the marathon route.

Runners who are still running are being rerouted to a new finish-line.

It is believed to be intentional due to the coordination of the explosions.

There are four runners from the Shreveport-Bossier area, no word if they were affected:

  • Frank Bright, 70, Shreveport
  • Elodie Burlet, 36, Shreveport
  • Brittany Glen, 21, Bossier City
  • Christopher Huff, 35, Shreveport
