Refinery explosion rocks Puerto Rico

An enormous explosion rocked the Caribbean island of Puerto Rico early Friday as 14 fuel tanks exploded at a gasoline refinery, leaving two people injured, officials said. The huge fireball covered the area around the Caribbean Petroleum plant with thick black smoke, prompting fears that the accident could cause serious environmental damage to the surrounding area, just outside the capital.
Over 100 fire-fighters at the scene were working to contain the blaze but officials said it would likely be several days before it was contained. Authorities have not been able to confirm the cause of the blast, which created a 2.8 magnitude jolt on the Richter scale, according to the Puerto Rico Seismic Network.
