LIMA, Peru — The President of Peru declared a state of emergency in Lima on Monday and ordered troops to assist police in curbing a wave of violence, following widespread protests over the recent murder of a popular singer.

President Dina Boluarte’s administration released a decree stating that the state of emergency will persist for 30 days, with some civil liberties, including those related to public assembly and travel, being restricted. This implies that law enforcement and military personnel can make arrests without court orders.

In the past few months, Peru has faced a rise in homicides, violent extortion, and attacks on public venues. Authorities recorded 459 homicides between Jan. 1 and March 16, and 1,909 reports of extortion in January alone. Public anger peaked after the assassination of Paul Flores, the 39-year-old lead vocalist of cumbia band Armonia 10, on Sunday.

In the legislature, opposition members of Congress sought a vote of no confidence in Interior Minister Juan José Santiváñez, alleging insufficient action to tackle escalating violence. This matter is slated for discussion in the legislative assembly later this week.

Flores was killed early Sunday when gunmen assaulted the bus carrying him and his band members following a concert in Lima. Cumbia is a Latin American musical genre performed to the beat of drums, maracas, and other instruments.

The violence targeted at the famous singer was not the sole violent incident over the weekend. On Saturday, an explosion at a restaurant in the capital left at least 11 people wounded.
