Mexico's Pemex sees high cost from pipeline attacks

MEXICO CITY, Sept 10 (Reuters) - A series of attacks that caused explosions on Mexico's oil and gas pipelines on Monday will cost state oil monopoly Pemex "hundreds of millions of dollars", Pemex Chief Executive Jesus Reyes Heroles said.

Reyes Heroles also told Mexican radio that disruption to Pemex's natural gas pipelines would hit around 25 percent of the country's natural gas supply for at least a day.
