SAN SALVADOR, El Salvador (AP) — U.S. Peace Corps volunteers returned to El Salvador Friday for the first time since the American force left in 2016 because of violence in the Central American country.

It was the latest sign of a thaw in U.S. relations with El Salvador, whose President Nayib Bukele was once shunned because of his harsh crackdown on street gangs.

It was also a sign of how much Bukele’s widespread arrests of suspected gang members - which also jailed a considerable number of apparently innocent young men - has reduced the country’s once-fearsome homicide rate.

The Peace Corps said the first nine volunteers would work on community economic development, education, and youth initiatives. All nine had previously worked two-year stints in other Central American countries.

“Today is not just a celebration, it’s a commitment to continue building on the decades-long partnership with the people of El Salvador,” said Peace Corps Director Carol Spahn.

More than 2,300 Peace Corps Volunteers had worked in El Salvador since 1962. The Peace Corps volunteers left after El Salvador’s gang-fueled homicide rate reached a high of 106 murders per 100,000 inhabitants on 2015. That year there were 6,658 killings in the country of 6.3 million.

Under a state of emergency originally declared in 2022 and still in effect, Bukele’s government has rounded up about 81,900 suspected gang members in sweeps that rights groups say are often arbitrary, based on a person’s appearance or where they live. The government has had to release about 7,000 people because of a lack of evidence.
