Czech Prime Minister Petr Necas said Monday his country would freeze plans to ratify a controversial international online anti-piracy accord after mounting off-and-online protests.

"The cabinet cannot accept a situation in which the bedrock of liberty and free access to information is endangered," Necas was quoted as saying by the Czech news agency CTK.

"I will not support a treaty that could limit human rights and freedoms," Miskov said in a statement.

The decision by the Czech and Slovaks government comes in the wake of a move last week by Poland, which also froze its ratification process.

ACTA was negotiated between the 27-nation European Union, Australia, Canada, Mexico, Morocco, New Zealand, Japan, Singapore, , Switzerland and the United States.

"ACTA is a serious attack in in the . We're convinced parliament shouldn't ratify it," said Mikulas Ferjencik, deputy leader of the local based on the Swedish cyber-freedom movement of the same name.

In addition to street rallies and online protests, anti-ACTA "hacktivists" have also launched cyber attacks on the Czech government and Necas's ODS party.
