Protesters are gathering in several European cities to voice anger at an international copyright treaty that they fear will lead to censorship on the Internet.
Several European countries have signed the Anti-Counterfeiting Trade Agreement, or ACTA, but ratification remains in question as contempt is building against it, mostly from young people.
Strong opposition to the treaty emerged in Poland last month and is now spreading across Europe, where protests are expected in many cities.
Some of the first to take to the streets were hundreds who rallied in front of a government building in the Lithuanian capital of Vilnius Saturday carrying signs that said "Stop ACTA."
Dozens are also marching in Warsaw.
