State Department spokesperson Adam Ereli said the arrests amounted to harassing citizens for exercising their political and civil rights.
CIP is financed by the Washington-based National Democratic Institute, which promotes democracy in the former Soviet Union and other regions.
The Belarusian government outlawed the group two years ago.
CPJ Europe and Central Asia Program Coordinator ALEX LUPIS, who had just returned from a trip to Belarus, told an RFE/RL briefing on 15 February that he found conditions that make it almost impossible for journalists to report independently on the campaign leading to the country's 19 March presidential election.
Lupis said the Belarusian government is "criminalizing" independent journalism, and forcing journalists to leave the country, change professions or join the state-controlled media. There is a "Cold War atmosphere" in Belarus, Lupis said, adding that President Alyaksandr Lukashenka makes up the rules of the game. The Internet, he said, is the "last free outlet" where independent journalists can publish, but Russia and Belarus are updating their media laws in order to restrict Internet usage. Numerous journalists with whom Lupis spoke said that they miss the support they used to receive from nongovernmental organizations such as IREX and Internews, which were once active in Belarus.
Lupis believes that the government in Belarus bans independent journalism because it fundamentally "mistrusts its own people."
