PERU’S president declared a state of emergency in the capital on Monday and ordered the deployment of soldiers to help police address a surge of violence, amid widespread outcry a day after the killing of a popular singer.

President Dina Boluarte’s government published a decree saying that the state of emergency will last 30 days, and authorities will restrict some rights, including the freedom of assembly and movement. 

That means the police and the army would be able to detain people without a judicial order.

Peru has seen an increase of killings, violent extortion and attacks on public places in recent months. 

Police reported 459 killings from January 1 to March 16, and 1,909 extortion reports in January alone. But outrage crested after the killing Sunday of Paul Flores, the lead singer of the cumbia band Armonia 10.

In Congress, opposition lawmakers requested a vote of no confidence against Interior Minister Juan Jose Santivanez for what they say is a lack of a plan to fight rising violence. 

The vote is expected to be discussed in the Congress’s plenary later this week.

Mr Flores was shot to death early on Sunday when assailants attacked the bus he and bandmates were travelling in after a concert in Lima.
