Men with tight hair are wearing only underwear and sitting on top of each other.

Most of them have large tattoos on their bodies.

These photos, which have been posted on Twitter in the new El Salvador office in recent days, were taken at El Salvador prison.

This is a scene where prison inmates are gathered together in an auditorium, etc. while the guards are searching the cell.

With the recent increase in murders by violent organizations, President Naive Buquele El Salvador took place in prisons around the world after ordering a 24-hour blockade of prisoners imprisoned by a gang on Wednesday (local time).

Most of the prisoners in the picture are believed to be members of El Salvador criminal groups called 'maras'.

El Salvador, where notorious marathoners such as 'MS-13' and 'Vario 18' make terrible crimes, is one of the most prominent crimes in South America with high crime rates.

Many El Salvadors have fled their homeland, avoiding gang threats.

The 38-year-old President of Buquele has been in the fight against the gang since he took office in June of last year.

In the midst of strong crime, El Salvador's murder rate fell from 51 per 100,000 population in 2018 to 35.8 last year, and thanks to these achievements, President Vukele has gained a high approval rating of 80-90%.

However, President Buquele's unstoppable policy promotion with public opinion also brought about controversy over politics.

When the borrowing plan for the expansion of military equipment in February was blocked by the National Assembly, it was typical to bring armed guards into the National Assembly.

The human rights of criminals were not a consideration at all for President Buquele.

Following the containment measures to prevent the spread of Corona19, the activity of the gangs, which had been quiet, has recently increased again, and President Vukele declared an emergency in prison and issued a blockade.

In order to prevent gang members from continuing to conduct crimes while in jail, the prisoners were held in prison cells without allowing a minute to go out, and all "out of the sun" was blocked.

The bosses were moved to solitary confinement, and competing members were brought into one room to prevent internal communication.

The boards were painted outside the bars so that they could not communicate with each other through gestures.

Corona 19 is in full swing outside, but the prisoners were superimposed and searched for cells.

The photos inside the prison, released by the President's office to explain the move, have sparked backlash from human rights groups.

"It's incredibly inhuman pictures," Dunkon Tucker of Amnesty International, an international human rights group, wrote on Twitter, saying, "The scenes of the darkest moments in human history come to mind."

"We need to ensure that El Salvador does not become another dictatorship," said Human Rights Watch's Jose Miguel Bivanco, and asked the Organization of the Americas (OAS) to review the announcement of the "American Democratic Charter."
