During a short statement to the country, President Obama promised to find out who perpetrated a bombing attack at the Boston Marathon this afternoon.
"We still do not know who did this or why," Obama said. "And people shouldn't jump to conclusions before we have all the facts. But make no mistake — we will get to the bottom of this. And 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."
Obama also offered Boston the full support of the American government.
