Libya has announced that a new round of voting for a constitutional panel will be held in a number of regions later this week, days after violence prevented some people from taking part in the first round.

Libyan Electoral Commission chief Nuri al-Abbar said people living in the eastern region of Derna and the southern areas of Sebha, Oubari, Murzak, and Kufra, who were not able to go to polling stations on February 20, could vote on February 26.

The Thursday voter turnout was 45 percent. Only a third of the country’s 3.4 eligible voters registered.

Before the voting was held on Thursday, at least five polling stations in Derna were damaged in bomb attacks.

In the same city, gunmen also killed the caretaker of a school scheduled to be used as a polling station.

Members of Libya’s ethnic minority Toubou and Tuareg group also stopped electoral material from being dispersed in the southern regions, preventing people from electing a panel tasked to draft a new constitution.

The boycott by Libya’s minority groups, including the Amazigh, comes as six of the panel’s 60 seats are reserved for their representatives.

The violence erupted although the Libyan interior and defense ministries said more than 50,000 police and army forces had been deployed to secure the 1,500 polling stations in the country.

Libya has been witnessing numerous clashes between government forces and rival militia groups, who played a key role in the 2011 popular uprising that toppled former dictator Muammar Gaddafi.

The former rebels refuse to lay down arms despite efforts by the central government to impose law and order.
