Gunmen in San Pedro Sula, Honduras have kidnapped a prominent teenage AIDS activist.
Eighteen-year-old Keren Dunaway Gonzalez was kidnapped Tuesday with her mother near the offices of the Llaves Foundation, which helps children with AIDS.
The mother, Rosa Gonzalez, a United Nations ambassador for children with the disease, was freed, but Keren remains captive.
A Llaves spokeswoman said Keren is HIV positive and must be let go so she can take the treatments necessary to prevent infections.
The kidnappers have yet to demand a ransom.
Keren has spoken at international AIDS conferences and also runs a magazine and radio show for HIV-positive children.
Honduras is one of the world's most violent countries, plagued by gang wars, drug traffickers and poverty.
