The AFP has a bit more on that shoot out in Ajdabiya:

One person was killed on Saturday and another  was wounded when unknown gunmen opened fire near a polling station in Libya's restive east, an official told AFP.

The attack took place in the city of Ajdabiya, where unrest had already disrupted voting in the country's first free national ballot in decades.

A depot in Ajdabiya containing electoral material was torched earlier this week, according to an official in Benghazi, the cradle of last year's uprising.
