Spain’s government has ordered police to seize control of polling places and ballot boxes ahead of Sunday’s planned independence referendum in the country’s Catalonia region. On Thursday, Barcelona police sealed off a warehouse containing 10 million paper ballots. Independence activists say they’ve had election materials seized, and the Spanish government has shut down pro-independence websites in a move that’s drawn comparisons to the former Egyptian dictator Hosni Mubarak. Spain’s top prosecutor has said he won’t rule out the possible arrest of Catalonia’s regional president.
