Two Iranian men have been charged by British counter-terrorism police under the National Security Act, authorities announced Wednesday.

Nematollah Shahsavani, 40, and Alireza Farasati, 22, face charges related to alleged national security offenses. The charges were filed under Britain's National Security Act, legislation designed to address modern security threats.

Counter-terrorism police led the investigation that resulted in the charges against both men. The National Security Act provides law enforcement with updated tools to prosecute offenses related to state threats and espionage activities.

The case represents one of the early applications of the National Security Act since its implementation. Further details about the specific allegations and court proceedings are expected to emerge as the case moves through the legal system.
