The Spanish government said Monday ousted Catalan leader Carles Puigdemont has traveled to Brussels.
The information came from official who requested anonymity because he was not authorized to be named in the media. The trip couldn't be confirmed by Puigdemont's aides.
Puigdemont was among those Catalan officials fired on Saturday by Spain as central authorities in Madrid take over affairs in the northeastern region after Catalan lawmakers voted Friday for independence.
Earlier Monday, Spain's state prosecutor called for rebellion and sedition charges to be brought against Catalonia's leaders over their push to separate from Spain.
Attorney-General Jose Manuel Maza also called for charges of misuse of funds to be laid.
Under Spain's legal system, the request goes to a judge for consideration. Maza asked the judge to call the seccessionist leaders to tesify.
