President Barack Obama appears in the White House briefing room after police arrested the lone surviving suspect of the Boston Marathon bombings.

　　随着警方逮捕另一位波士顿爆炸案嫌犯，美国总统奥巴马在白宫情报室发表讲话。

　　U.S. PRESIDENT BARACK OBAMA SAYING: "Obviously tonight there are still many unanswered questions. Among them: Why did young men who grew up and studied here as part of our communities and country resort to such violence? How did they plan and carry out these attacks, and did they receive any help? The families of those killed so senselessly deserve answers ." He pledged that the United States would find out whether the two brothers suspected of carrying out the bombings had help.

　　美国总统奥巴马说：“显然，今晚仍然还有许多问题没有解决，包括为什么在我们社区、在我们国家长大和学习的孩子会做出这种暴力行为。他们是如何计划和执行这些袭击的，是否有帮手。这些无辜受害的人们需要答案。”奥巴马承诺美国将查出涉嫌实施爆炸案的两兄弟是否有帮凶。

　　U.S. PRESIDENT BARACK OBAMA SAYING: "We will determine what happened, we will investigate any associations that these terrorists may have had and we'll continue to do whatever we have to do to keep our people safe." One suspect was killed in an overnight shootout with police. The second suspect was arrested in the Boston suburb of Watertown, ending the manhunt.

　　美国总统奥巴马说：“我们将搞清楚事情发生的原因，我们将调查与这些恐怖袭击有关的任何联系，我们将一如既往的尽最大努力保护人民的安全。”一名嫌犯在昨晚与警方的枪战中被杀，第二名嫌犯在波士顿郊区水城被逮捕，搜捕行动宣布结束。
