Protesters block traffic as they march towards the Puerta del Sol plaza in central Madrid, Sunday May 15, 2016. The demonstration is to mark the fifth anniversary of a protest movement that led to the creation of Podemos, now Spain's third most-popular political party. Main banners read ' Rescue the democracy', 'Stop evictions', "The TTIP devours us", "The press, the radio and TV are prisoners of PP (Popular party)". (AP Photo/Paul White)
