Thousands of Argentines participate in mass street tango

Hundreds of couples took to the streets of downtown Buenos Aires on Saturday night, turning a main avenue into a three block open-air tango dance floor. The “Great National Milonga” is a tango music festival, organised to celebrate Tango Day, which commemorates the birth of iconic tango singer Carlos Gardel and composer Julio De Caro, both born on 11 December.
