Masked men broke onto the set of a public television channel in Ecuador waving guns and explosives during a live broadcast Tuesday, and the president issued a decree declaring that the South American country had entered an “internal armed conflict.”

The men armed with pistols and what looked like sticks of dynamite entered the set of the TC Television network in the port city of Guayaquil and shouted that they had bombs. Noises similar to gunshots could be heard in the background. It was not immediately clear if any station personnel were injured.

Ecuador has been rocked by a series of attacks, including the abductions of several police officers, in the wake of a powerful gang leader’s apparent escape from prison. President Daniel Noboa said Monday that he would declare a national state of emergency, a measure that lets authorities suspend people’s rights and mobilize the military in places like prisons.

Shortly after the gunmen stormed the TV station, Noboa issued another decree designating 20 drug trafficking gangs operating in the country as terrorist groups and authorizing Ecuador’s military to “neutralize” these groups within the bounds of international humanitarian law.

The government has not said how many attacks have taken place since they announced that Los Choneros gang leader Adolfo Macías, alias “Fito,” was discovered missing from his cell in a low security prison on Sunday. He was scheduled to be transferred to a maximum security facility that day.

Authorities also have not said who is thought to be behind the attacks, which included an explosion near the house of the president of the National Justice Court and the Monday night kidnappings of four police officers, or whether they think the actions were coordinated.

Police said one office was abducted in the capital, Quito, and three in Quevedo city.

The government has previously blamed members of the main drug gangs for similar strikes. In recent years, Ecuador has been engulfed by a surge of violence tied to drug trafficking, including homicides and kidnappings.

Macías’ whereabouts are unknown. Prosecutors opened an investigation and charged two guards in connection with his alleged escape, but neither the police, the corrections system, nor the federal government confirmed whether the prisoner fled the facility or might be hiding in it.

In February 2013, he escaped from a maximum security facility but was recaptured weeks later.

On Monday, Noboa decreed a national state of emergency for 60 days, allowing the authorities to suspend rights and mobilize the military in places like prisons. The government also imposed a curfew from 11 p.m. to 5 a.m.

Noboa said in a message on Instagram that he wouldn’t stop until he “brings back peace to all Ecuadorians,” and that his government had decided to confront crime. The wave of attacks began a few hours after Noboa’s announcement.

States of emergency were widely used by Noboa’s predecessor, Guillermo Lasso, as a way to confront the wave of violence that has affected the country.

Macías, who was convicted of drug trafficking, murder and organized crime, was serving a 34-year sentence in La Regional prison in the port of Guayaquil.

Los Choneros is one of the Ecuadorian gangs authorities consider responsible for a spike in violence that reached a new level last year with the assassination of presidential candidate Fernando Villavicencio. The gang has links with Mexico’s Sinaloa cartel, according to authorities.

Experts and authorities have acknowledged that gang members practically rule from inside the prisons, and Macías was believed to have continued controlling his group from within the detention facility.
