Videos produced by religious advocacy group the Iona Institute are back on YouTube this evening after they were taken down for a time today.

A spokesperson for Google, which owns the video website, said that the films were removed after a verification problem arose with the group's account.

Earlier there had been suggestions that the removal of the films, which include one promoting marriage as between a man and a woman, had been the subject of censorship.

However, that notion was dispelled by both sides tonight.

The director of the institute, David Quinn, acknowledged there was nothing sinister in the removal of the videos.

He said he was now happy they were back on YouTube.

A Google spokesperson said while it was unfortunate that an inconvenience was caused, the problem lay with a verification issue and had nothing to do with censorship.
