An explosion at an oil refinery in an industrial area of Bangkok sparked a massive fire on Wednesday, sending a thick column of smoke into the air that can be seen across the Thai capital.
No one appears to have been injured in the blaze, which began after a loud blast about 7.30am local time, according to a spokeswoman for the refinery firm.
Chaveewan Kiatchokchaikul of Bangchak Petroleum said the fire had been brought under control and its cause is being investigated.
Emergency services sent to the scene said there had been no casualties reported so far, AFP reports.
The Bangchak oil refinery employs about 600 people is located in a large industrial estate in a sprawling suburb.
It is among Thailand's biggest refineries and 120,000 barrels of oil are processed at the site every day, a company official said.
