One charred body -- a male protester -- was found in the U.S. Embassy compound, embassy spokesman in Belgrade William Wanlund said
"I can tell you that it was not an American," said U.S. State Department spokesman Sean McCormack. All Americans were safe and accounted for, McCormack said.
Belgrade fire officials said the body was found in an "unoccupied area" of one of the embassy buildings, he said, around the same area as that reached by the demonstrators.
