"National Oil Corporation has evacuated staff from both Sidra and Ras Lanuf terminals for their safety due to armed clashes in the area. The loss in oil production is around 240,000 bpd and a planned tanker entry today to Sidra has been postponed," the statement said.
According to the statement, NOC is monitoring the developments and stresses the need to bring the people responsible for the attack to justice.
Earlier in the day, militants affiliated with al-Qaeda* terrorist group attacked the oil terminals. Troops from the Libyan National Army (LNA) repelled the attack.
