Rowdy teacher protests in southern Mexico have caused delays and bottlenecks in transporting fuel from the country's top refinery in Salina Cruz, and state oil giant Pemex is on alert for new roadblocks, a company official said on Wednesday.
Blockades on Tuesday caused long lines of tanker trucks unable to transport fuels for hours.
Late last week, Pemex warned that road blockades by protesters could cause the facility's storage tanks to reach their limits and potentially force the company to shut the refinery, Pemex's biggest with a capacity to process 330,000 barrels of crude per day . . .
