Barack Obama has responded to a series of crude bombs which rocked the finish line of the Boston marathon on Monday evening.
The US President was grave as he addressed the nation from the White House press office. “We will find out who did this and we will hold them accountable,” he said.
“Make no mistake we will get to the bottom of this and we will find out who did this and find out why they did this.
“Any responsible individuals, any responsible groups will feel the full weight of justice”.
Mr Obama, who carved out his law career in the neighbouring state of Illinois, paid tribute to the strength of the Boston community.
“I”m supremely confident that Bostonians will pull together, take care of each other and move forward as one proud city,” he said.
