BAGHDAD, Sept. 4 (Xinhuanet) -- Saboteurs on Saturday set fire are fined oil products pipeline in northern Iraq as they kept up relentless attacks on Iraq's oil production industry, Dubai-based al-Arabiya TV reported.

    The attacked pipeline, near a region where the main crude export pipeline was blown up on Thursday, linked the northern oil center of Kirkuk to the country's biggest oil refinery at Baiji, some 200km north of Baghdad, the channel said.

    The main crude export pipeline passes through Baiji before continuing north to the Turkish port of Ceyhan.

    It was still on fire after Thursday's attack, although sand walls were being built around it.

    Exported oil in northern Iraq were running at a postwar high of 600,000 barrel per day before saboteurs attacked the pipeline,which has been mostly shut since the US-led invasion.

    Insurgents have launched repeated attacks on Iraq's vital oil industry in a bid to undermine the interim government's reconstruction efforts. Enditem
