Libyan forces say they have carried out airstrikes against a militia attacking key oil ports in the east.
Ahmed al-Mesmari, a spokesperson for the self-styled Libyan National Army, said the airstrikes late on Sunday targeted fighters loyal to Ibrahim Jadhran, who are trying to seize the Ras Lanuf and el-Sidr oil terminals.
Libya's National Oil Corporation said on Monday that the attack by Jadhran's forces caused "significant" damage to at least two storage tanks and warned of further damage to oil infrastructure as well as environmental contamination.
The assault on the terminals, which began on Thursday, has forced the national oil firm to suspend exports and evacuate its employees.
Libya slid into chaos after the 2011 uprising that toppled and killed Muammar Gaddafi, and today is largely ruled a patchwork of feuding militias.
