Boston Marathon explosions kills three and injures 140

  • At least three people were killed and around 140 injured after two explosions near the finish line of the Boston Marathon on Monday.

    The FBI has launched an investigation, describing it as a "potential terrorist inquiry".

    At least 17 people were critically injured, according to officials, who added that the injuries include several amputations.

    One of the dead was an eight-year-old boy.

    In a televised address, President Barack Obama pledged to bring those responsible to justice.

    "We will find out who did this. We'll find out why they did this. Any responsible individuals, any responsible groups, will feel the full weight of justice," he said.

    The first explosion took place at about 2:50 pm local time on the north side of Boylston Street, around two hours after the winners crossed the line. Seconds later, another explosion occurred between 50 and 100 yards from the first blast.

    This year’s annual Boston Marathon included around 23,000 runners and was watched by hundreds of thousands of spectators.

    It is held on Patriots' Day, a state holiday in Massachusetts, which commemorates the first battles of the American Revolution in 1775.
