Two huge explosions rocked the Boston Marathon finish line at Copley Square just before 3 p.m. today, apparently causing numerous casualties.
"I saw two explosions. The first one was beyond the finish line. I heard a loud bang and I saw smoke rising," said Herald reporter Chris Cassidy, who was running in the marathon."I kept running and I heard behind me a loud bang. It looked like it was in a trash can or something. That one was in front of Abe and Louie's. There are people who have been hit with debris, people with bloody foreheads."
"There are at least a dozen that seem to be injured in some way," Cassidy said.
