A court in Belarus has branded a book of news photographs "extremist," agreeing with the state security agency that the book set out to humiliate the country.

The work consists of photos taken in 2010 that won prizes in the 2011 Belarus Press Photo competition, including images of people protesting against authoritarian President Alexander Lukashenko and a police crackdown on them.

Some of the photos were made by photographers working for international news agencies, including The Associated Press, Reuters and AFP.

The security agency, which is still called the KGB, said the photos were selected to "humiliate national honor and dignity."
