Financial Tribune - As of Thursday, an unidentified entity deploying jammers has disrupted GPS services in Tehran, a deputy ICT minister says.

Hossein Fallah, who also serves as director of Communications Regulatory Authority of Iran, added that recent disruptions in GPS services have been caused by �deliberate acts� of an unnamed entity.

�This is not the first time that such disruptions in services have been detected. Despite the repeated disavowals of security agencies and even Iran's Supreme National Security Council against the use of GPS jammers, such disruptions have continued,� he told IRNA.
