Mexico City: Two Mexican journalists were killed by asphyxiation and their bodies left naked with their hands and feet bound in Mexico City, Contralinea magazine reported Thursday.

The bodies of Ana Maria Marcela Yarce Viveros, the founder of the weekly investigative journalism magazine, and Rocio Gonzalez Trapaga, a freelance, former reporter for Televisa channel, were found in a park in Iztapalapa, a working class neighbourhood in the southeast of the capital, according to the magazine's website.

"They were brutally killed. For the moment we don't have more information. We don't know why they were killed," Janet Alba, assistant to the magazine's director, told AFP.

"We call on the authorities to shed light on this sad event," said the brief message on the website.

The bodies "were found this morning (Thursday) and identified this afternoon," an official from the city's attorney general's office told AFP, without giving further details.

Hands, feet tied

The magazine's director, Miguel Badillo, told Formula radio that the women had been asphyxiated and their bodies were found naked with the hands and feet tied.

They disappeared after leaving the office at around 10pm Wednesday, he said.

Mexico is the most dangerous country in the Americas for journalists, according to a UN report published in June.

Editor found dead a week ago

Humberto Millan, an online newspaper editor and radio show host, was found dead a week ago in the northwestern state of Sinaloa, one day after armed men seized him at gunpoint.

Since the start of the year, five other journalists have been murdered in the country, according to the Washington-based Inter-American Commission on Human Rights.
