The Department of Justice has declined to comment on reports in Britain that the British Ministry of Defence has been listening to international telephone calls from this country for almost a decade. Telecom Eireann said tonight that it had no knowledge of the activities.

A report on Channel 4 Television News said a tower in Capenhurst, Cheshire, was used to intercept all telephone signals between Ireland and Britain from 1989 to when it was closed down earlier this year. The tower has now been put up for sale by the Ministry of Defence for about twenty million pounds.
