About 2,000 young people angry over high unemployment have spent the night camping in a famous square in Madrid as a political protest there grows.
A big canvas roof was stretched across Puerta del Sol square, protesters brought mattresses and sleeping bags and volunteers distributed food.
The nature of the peaceful protest, including Twitter messages to alert supporters, echoed the pro-democracy rallies that revolutionised Egypt.
The Madrid protests began on Sunday.
