Two of the three journalists kidnapped in recent days in the southern Mexican state of Guerrero have been released unharmed, Article 19, a non-governmental press freedom organization, announced yesterday Saturday.

Silvia Arce and Alberto Sanchez, a couple who run the news website RedSiete, were released in the early hours of yesterday, the NGO said.

They were kidnapped on Wednesday by gunmen who stormed the site’s offices in Taxco, according to eyewitnesses cited by Article 19.

Pedro Cardenas, a member of the organization, told Reuters that the release of the couple was confirmed by a person who has a close relationship with them, avoiding giving more details.

Marco Toledo, the director of the weekly newspaper El Espectador de Taxco, remains in the hands of his captors along with his son, but his wife has been released, according to the same source.

Mr. Cardenas emphasized that the woman did not suffer violent treatment, citing sources close to the family.

The attorney general’s office in Guerrero state announced on Thursday that an investigation is underway into the disappearance of five people in the tourist town of Taxco, including journalists Toledo, Arce and Sanchez.

The attorney general’s office did not immediately respond when Reuters sought comment on developments in the cases.

Mexico is among the most dangerous countries in the world for media workers. So far this year, Article 19 has reported five murders of journalists. Last year was the deadliest year since the NGO began collecting data in 2000: 13 journalists were killed.
