Euro MPs have “strongly” criticised telecoms firm Nokia Siemens Networks for providing “surveillance technology” to the Iranian authorities.
In a resolution adopted on Wednesday, the MEPs said the hardware was instrumental in the “persecution and arrests of Iranian dissidents”.
But Nokia Siemens said that the implication that it had provided censorship technology was “wrong”
It has previously said that it had installed “lawful” technology in 2008.
“We will be clarifying any inaccuracy in their understanding of our business in Iran with the European Parliament,” Ben Roome of the firm told BBC News.
Nokia Siemens said the technology that it had installed was similar to that used “in all EU member states and the US”.
