State-owned Mexican oil company Pemex reported Tuesday losses of $5.2 billion in the second quarter due mainly to lower petroleum prices.

It said prices of Mexican crude were 44 percent lower than in the same period a year ago.

In the first quarter of 2015, Pemex lost $6.5 billion.

The new losses -- 84.6 billion pesos in local currency -- far surpass those of the second quarter of 2014, which came in 52.3 billion pesos.
