'They smashed me in the head': anger at Piñera as Chile's bloodied protesters allege brutality

Death toll rises to 15 in worst unrest Chile has faced since Pinochet, as armed men in masks prowl Santiago firing at defiant protesters

As helicopters clattered overhead and army truck convoys rumbled through the city, armed men in masks prowled the streets of Santiago on Monday night, firing at protesters defying a fourth night of curfew under martial law.

By Tuesday morning, the official death toll stood at 15. The Chilean government claimed all the casualties were looters, but there were widespread allegations of brutality by the military, following the declaration by president, Sebastiin Pinera that his country was "at war".
