MEXICO CITY – A leftist guerrilla group claimed responsibility Tuesday for a series of bombings of pipelines operated by Pemex, Mexico's national oil company, and authorities moved quickly to protect the nation's oil and gas industry from further attacks.
The Popular Revolutionary Army (known by the Spanish initials EPR) said in a communique that it would continue the bombing campaign until the government disclosed the whereabouts of two group members said to have disappeared in Oaxaca last year.
