Men from the western Libyan town of Zintan have been sent to reinforce security on the Algerian border as well as around oil fields in the area, the head of Libya's Petroleum Faculty Guard, Col. Ali Elahrash, said Jan. 23, Reuters reported. Members of the guard who were on leave quickly returned to work as well. Most of the forces have been sent to patrol the border, and there are enough men and equipment to protect the area, Elahrash said. The Petroleum Faculty Guard usually deploys 50 to 100 men at each oil field, but now each site has at least 100 men, the force's public relations director, Walid Hassan Mohammed, said. The security boost is in response to the recent hostage crisis at an oil facility in Algeria.
