Belgrade Citadel Mined.

New York Times 100 years ago today, November 30, 1912:
Tradespeople Being Moved Away as a Precautionary Measure.
    LONDON, Nov. 29.— A dispatch from Vienna says that a message, received there late to-night from Belgrade, declares that the citadel in Belgrade has been mined and may be blown up on the entry of foreign troops.
    A majority of the tradespeople, officials, and leading manufacturers of Belgrade, by Government order, have moved to Nish and Leskovatz, and others are preparing to depart from the Servian capital.
