More than 90,000 people have been detained, and some 8000 have been released after being found not guilty, according to official sources.
Bukele’s campaign against gangs has reduced homicides to historically low levels in the Central American country, but human rights groups accuse the security forces of committing abuses.
According to the Salvadoran Government, MS-13 and another gang, Barrio 18, are responsible for the deaths of about 200,000 people in three decades.
The two gangs once controlled an estimated 80% of the country, and El Salvador had one of the highest homicide rates in the world.
The United States has designated MS-13 and several other gangs in Central and South America as foreign terrorist organisations.
