Libyan rebels drive their vehicle to the font line near Ajdabiya, in Benghazi, eastern Libya on April 6. Libyan rebels trying to retake the northeastern oil port of Brega were pushed back to the city of Ajdabiya by Muammar Gadhafi's armed forces. The rebels were coming under heavy shelling some 30 kilometres outside Adjabiya, located between Brega and the rebel stronghold of Benghazi in the east, one source in Benghazi told the German Press Agency dpa.
