Iran said it has neutralized a cyber attack generated in America's Dallas city against the servers of the Iranian ministry of culture, the Prensa Latina news agency reported. Tehran said the electronic aggression was launched through servers in Malaysia and Vietnam, but was repelled by experts from the Supporting and Protecting Works of Art and Culture Center.

Prensa Latina said Iranian authorities frequently denounce similar aggressions against industrial centres and nuclear power plants from the US and Israel and have been forced to create, along with Iranian specialists, cyber battalions that operate 24 hours a day.

Cyber attacks against Iranian networks began in 2010 with a virus known as Stuxnet, whose target was computers at nuclear power plants.

These actions were part of a programme that included the assassination of some Persian atomic energy scientists, according to Iranian investigations.
