Foreign Affairs has confirmed that no Canadians were injured in the Boston Marathon bombings.

There were more than 2000 Canadians running in yesterday's race. At least 130 participants live in the Ottawa area.

The twin blasts went off at about 2:50pm, Monday afternoon, as crowds of runners and spectators gathered around the finish line.

Three people are confirmed dead, the youngest an 8-year-old child. More than a hundred people were injured, several facing severe trauma such as missing limbs.

On social media, many Canadians wrote about the difficulty leaving Boston in the aftermath of the bombings; however, some were able to leave by car.

Some participants are expected to fly into Ottawa from Boston today.
