New Delhi: Setting aside months of speculation, a top government official Wednesday said the Blackberry mobile services do not pose a threat to national security, indicating a government go-ahead for its operation in the country.

"People are buying Blackberry. There is no threat from the Blackberry services," Telecom Secretary Siddharth Behura told reporters on the sidelines of a telecom summit here.

The Blackberry services came under the government scanner following security agencies' concern that the unintercepted data through its network could be used by terrorists.

The government asked Research in Motion (RIM), the makers of Blackberry, not to list any fresh subscriber till a server is placed in India to monitor contents.

"Security agencies have raised certain issues and the issues are being discussed. These discussions will continue with the company," Behura added.

Asked if the government would give approval to companies that have applied for starting Blackberry services, including the Tatas, the telecom secretary said: "BSNL also wants to start the service. There is no permission needed for starting value-added services. They do not have to seek our permission to start any service."
