LAGOS, Sept. 23 (Xinhuanet) -- Another Nigerian flowstation operated by US oil giant Chevron was shut down on Friday, a company spokeswoman told Xinhua, amid dangerous tension in the country's oil delta over the arrest of a militia leader.

    "We have closed the Robertkiri flowstation as a precautionary measure," Edith Azinge said. "We are monitoring the situation closely."

    The oil facility is close to the Idama flowstation, which was occupied on Thursday by over 100 armed militants of the illegal Niger Delta People's Volunteer Force (NDPVF).

    The closures have led to the loss of 26,000 barrels of oil production per day in OPEC Nigeria. Enditem
