美国总统奥巴马的发言人欧内斯特说，特勤局人员在白宫院内发现一个据信是小型无人机的“装置”。
欧内斯特星期一对随同奥巴马和第一夫人米切尔访问印度的记者说，这个装置看上去并不对白宫的任何人构成威胁。
他没有透露发现这个装置的具体位置，只是说，特勤局会随时提供更多资讯。
目前还不清楚当时奥巴马的两个女儿是否在白宫。
事情发生后，有关当局对通往白宫的道路进行了限制。
A spokesman for U.S. President Barack Obama says the Secret Service has recovered a "device" believed to be a small drone on the grounds of the White House.
Josh Earnest told reporters traveling with Mr. Obama and his wife, Michelle, in New Delhi Monday that the device did not appear to be an ongoing threat to anyone at the White House.
He did not say exactly where it was found, and said the Secret Service would provide more information when available.
It was not immediately clear if the Obamas' two daughters were home at the time.
The incident caused authorities to restrict access to the White House complex.
