Chile's President Sebastian Pinera on Thursday announced a series of measures to tighten public order in the wake of three weeks of anti-government protests that have left 20 people dead.
The legislative package, aimed at curbing violent demonstrations and looting, includes measures that would ban protesters from wearing hoods and burning barricades, and provides greater protection for police.
"We are convinced that this agenda represents and constitutes a significant and important contribution to improve our capacity to safeguard public order," said Pinera, who has rejected calls to resign.
He also said a special prosecution team would be established to try offenders while, in the longer term, intelligence gathering would be revamped.
Pinera's announcement came after demonstrations on Wednesday spread into Santiago's wealthiest neighbourhoods for the first time.
