Four Libyan oil export ports that were closed last week because of bad weather have reopened, a Libyan shipping source and port engineers told Reuters on Sunday.

Tankers were docking at the eastern Ras Lanuf, Es Sider, Zueitina and Brega ports as well as the western Zawiya terminal linked to the El Sharara field, they added.

On Friday state oil company NOC said bad weather had forced shutdowns at the Ras Lanuf, Es Sider, Zueitina and Zawiya terminals.
