President Obama is scheduled to travel to Boston Thursday, three days after the deadly bombings at the Boston Marathon.
As the city grapples with this tragedy, the president plans to speak at an interfaith service "dedicated to those who were gravely wounded or killed in Monday's bombing," White House Press Secretary Jay Carney said in a written statement.
Obama's visit comes as authorities are working around the clock to determine who is behind the twin blasts at the finish line of the marathon. Earlier today, the president vowed to bring to justice those responsible for this "act of terrorism," which he called a "heinous and cowardly act."
"It will take time to follow every lead and determine what happened. But we will find out," he said. "We will find whoever harmed our citizens, and we will bring them to justice."
