The Boston Globe has released eyewitness footage of the explosions which today rocked the city’s famous marathon.

The bombs, which went off among the crowd of spectators near the race’s finish line are believed to have killed at least two people and injured dozens of others.

The amateur footage shows a steady stream of runners still crossing the finish line as the explosions went off as well as the reactions of police. The video does also show glimpses of bodies lying prone behind the spectator barriers.
