UNITED NATIONS (Reuters) - New York City's bedbug epidemic has spread to yet another landmark in the city that never sleeps -- the United Nations, officials at the world organization said on Wednesday. The pests appeared at places like the Empire State Building and Bloomingdale's before reaching the city's center of international diplomacy on the East Side of Manhattan. The U.N. press office said a bedbug-sniffing dog had confirmed the presence of bedbugs in furniture in the basement of the Dag Hammarskjold Library, where the offices of the team overseeing the U.N. headquarter's $1.9 billion renovation project are housed.
