Members of the European Parliament expressed concern about a U.S. program that permits some level of data mining from Internet and mobile phone networks.

Slovakian lawmaker Jaroslav Paska said Tuesday he was concerned about the implications of data protection, privacy and bilateral security collaboration with the United States.
"The paranoid behavior of our American partners is regrettable," he said Tuesday.
The White House last week said President Obama was committed to finding the right balance between protecting civil liberties and the national security of the United States.
British lawmaker Claude Moraes expressed concern about the need to protect data across the European Union.
"Trust has clearly been breached," he said in a statement. "We must ensure U.S. public authorities processing EU citizen's data do so within our standards."
The European Parliament said most of its members "roundly condemned" the surveillance program, but said broad security cooperation with the United States was a top priority for the bloc.
