The British government is protesting against Twitter’s decision to withdraw access to user data used to investigate potential terrorist plots.
The information was previously used by the police and the MI5 intelligence agency.
However, the Telegraph newspaper cited industry sources, in a report on 25 April, saying the government’s access had been “blocked”.
Twitter did not immediately respond to a request for comment.
“We are protesting this decision. We are in talks with Twitter on getting access to this data,” a government spokesman said, according to the Reuters news agency.
The BBC understands that the data in question is available to private companies but the Home Office has been denied access to it.
