Army guards Mexico oil industry after blasts

---

MEXICO CITY, Jul 12 (Reuters): Extra soldiers and federal police were deployed to guard Mexico's oil wells and pipelines Wednesday after a rebel group said it caused explosions at fuel pipelines as part of an anti-government campaign.
State oil monopoly Pemex, a major US supplier, said it beefed up its police and army presence at installations after the left-wing Popular Revolutionary Army, or EPR, said Tuesday it was behind attacks on four pipelines in the past week. It vowed to carry out further attacks.
Pemex added two extra helicopters to its surveillance operations and was working with the defence ministry and federal police on the best way to guard the country's pipelines, which stretch over 14,000 km (8,700 miles).
