A suspected bomb on a railway line has hit a train carrying oil products near Baghdad, causing a huge fire.
One person was killed and four others were injured in the blaze.
The train was carrying oil derivatives from a refinery in Doura, south of the capital, where the incident occurred.
One police source said he believed a bomb targeted the train, while another said it may have been an accident. Reuters cameramen at the scene said the incident caused a huge blaze, with smoke and flame pouring into the air.
Police said one person had been killed. It was not immediately clear if they were on the train or passing by.
Separately, a bomb blew up an oil and a gas pipeline running from Kirkuk to a refinery at Baiji, about 180km north of Baghdad.
Pipelines running between the oil fields at Kirkuk and Baiji are frequently attacked by insurgents and saboteurs, as is the main oil export pipeline that runs from Baiji north to the Turkish port of Ceyhan.
That line has been out of commission for several weeks following a previous attack, hindering Iraq's ability to export oil, the mainstay of the economy.
