July 7 (Bloomberg) -- Armed militants targeting Nigeria’s oil industry shut 589,000 barrels of crude a day in two months, Daily Trust reported, citing Mohammed Barkindo, head of the Nigerian National Petroleum Corp.

The losses resulted from more than 12 attacks carried out between May and June, Barkindo told oil and gas workers at a meeting in the capital, Abuja, according to the report.

Oil installations valued at more than $110 billion are at risk due to the crisis in the oil-producing Niger River delta, the Abuja-based newspaper reported Barkindo as saying.
