Boston College tapes: NBC launches legal bid

The American news network, NBC, has made a formal request to have transcripts from Boston College's Belfast Project released.

Its news investigations team made the application to a US Judge, William Young, who is one of the few people to have read the entire archive.

Information from the recordings has led to a series of arrests, including that of Sinn Féin president Gerry Adams.

The project was designed as an oral history of the Troubles.
