A Libyan rebel updates drivers of security status as they head to the front line during an exchange of fire with pro Gadhafi forces, along the front line outside the eastern town of Brega, Libya Thursday, March 31, 2011. Libya conceded Thursday that Foreign Minister Moussa Koussa had resigned but claimed that it was a personal decision driven by health problems, not a sign that the embattled regime is cracking at the highest levels.
