By Nicolás Misculin BUENOS AIRES (Reuters) -Tens of thousands of Argentines marched in the streets of Buenos Aires on Wednesday, banging drums and chanting in a show of support for ex-president Cristina Fernandez de Kirchner as she started a six-year sentence under house arrest for corruption.

Protesters have denounced the leader’s incarceration and ban from public office as an act of political retribution.

An Argentine judge on Tuesday (June 17) put former President Cristina Fernandez de Kirchner under house arrest to serve out a six-year sentence for corruption in a case that has effectively brought down the country's most prominent politician in recent decades.
