A Chilean singer has bared her breasts in a red carpet protest at the Latin Grammy awards in the US.
Mon Laferte uncovered her chest emblazoned with the words "In Chile they torture, rape and kill" on Thursday.
Chile has seen almost a month of protests that started after a rise in subway fares and have grown into anti-government demonstrations.
On Friday, Chile announced it would hold a referendum on the constitution.
The protest took place as Mon Laferte walked the red carpet at the awards show in Las Vegas.
Also, as she accepted the award for best alternative album, Mon Laferte read a poem from Chilean writer La Chinganera, saying: "Chile, your pain hurts me."
She was one of several artists at the Latin Grammys who spoke about the current political climate in Latin American countries.
Protesters have been taking to the streets of Chile for almost a month, demanding greater social reform and a change to the country’s constitution.
The constitution dates back to the pre-democracy era of the military leader, Augusto Pinochet.
It does not currently establish the state’s responsibility to provide healthcare and education, which are two demands from the protesters.
On Friday, the government announced it would hold a referendum on the constitution in April next year.
According to Senate president Jaime Quintana, the referendum will ask voters whether they think the constitution should be replaced.
It will also ask voters who think it should be replaced to choose between three different bodies to draw up a new constitution. The options are a body of fully elected representatives, political appointees or an equal mix of both.
At least 20 people have been killed in the protests and more than 1,000 injured.
Chile’s independent National Human Rights Institute says it has brought legal action over 179 cases, including alleged murders, sexual violence and torture by the military police.
