I can't afford a seat inside a bar, but an SMS, no problem
Mass street drinking sessions fuelled clashes between Spanish youths and riot police early on Saturday, leaving 80 people injured and 70 arrested in Barcelona and Salamanca, police said.
Tens of thousands of young people gathered in cities around Spain on Friday night in an attempt to hold the biggest street drinking session or "botellon" ("big bottle"). In the southern city of Granada, police said 25,000 people joined the botellon.
Youths rallied revellers by email and SMS messages for "macrobotellones" in 20 cities around Spain on Friday, while authorities pleaded with parents to keep their children under control and warned of the danger of under-age drinking.
