Iraq's two oil terminals in Basra were attacked by suicide boat bombing on Saturday, official sources said.
But Qatar-based al-Jazeera news channel reported that a major oil export terminal in Iraq's southern port city of Basra was attacked by two suicide boats on Saturday.
One of the boats exploded alongside a vessel tied up at the terminal, and a second went off near the exclusion zone around oil facilities, said the channel. No reports of damage or casualties were given.
Iraqi authority has shut down the terminal after loading was interrupted by the explosions, the official sources said. Iraq's oil and electricity facilities were frequently targeted by insurgents, but it appeared as the first attack at the offshore terminal.
Most of Iraq's crude oil has been exported through the port in Basra since the end of US-British invasion last summer.
