(CNN) Four workers died in a massive oil rig fire that raged for hours off the coast of Mexico Wednesday.

Mexican state oil company Pemex said 45 workers were injured in the blaze, which began early Wednesday morning. Two of them are in serious condition, the company said.

Authorities evacuated about 300 people from the Abkatun Permanente platform after the fire started, Pemex said. At least 10 boats worked to battle the blaze for hours.

The fire had been extinguished by Wednesday night, Pemex said in a Twitter post.
