From Rami Al-Sheibi, the AP:  Clashes between rival factions of the Libyan rebels killed four people Sunday in the opposition stronghold of Benghazi, deepening the worst crisis so far for the movement after its chief military commander was killed , possibly by fighters from his own side.

One rebel group overran the base of another faction because they suspected that faction had freed some supporters of Moammar Gadhafi from an opposition prison, Rebel Information Minister Mahmoud Shammam said.

He said the clashes between rebel security forces and members of the al-Nidaa Brigade broke out around 3 a.m. on the western outskirts of Benghazi and left four rebels dead and six wounded. The main rebel force took control of al-Nidaa’s base after five hours of fighting, he said.

The violence comes two days after suspected al-Nidaa members attacked two prisons in Benghazi, facilitating the escape of some 200 to 300 inmates, including mercenaries, pro-Gadhafi fighters and regime loyalists. . . .  (photo: AP)
