WASHINGTON -- U.S. authorities say a man has been arrested trying to climb over a fence at the White House.

The Secret Service says the unidentified man was apprehended before he could get over the fence.

He had two bags with him and authorities are waiting for the Washington police to arrive to screen the bags' contents.

It is unclear why the man tried to climb the fence around the heavily guarded White House or what may be in the bags he was carrying.
