WASHINGTON, Oct. 24 (Xinhua) -- The U.S. Secret Service has intercepted two "suspicious packages" addressed to former President Barack Obama and 2016 Democratic presidential nominee Hillary Clinton, the agency said Wednesday.

The package intended for Obama was intercepted here on Wednesday morning, and the one intended for Clinton was addressed to her in Westchester County, New York, on Tuesday, the Secret Service said in a statement.

"Both packages were intercepted prior to being delivered to their intended location," it said. "The protectees did not receive the packages nor were they at risk of receiving them."

The packages were immediately identified during routine mail screening procedures, the Secret Service said, adding that the "potential explosive devices were appropriately handled."

The agency has initiated an investigation to determine the source of the packages.

The devices were recovered following the discovery of an explosive device found earlier this week in a mailbox at the Bedford, New York, home of liberal philanthropist George Soros.
