Which of the following is CORRECT? [originaltext] Libyan warplanes struck at

Libyan warplanes struck at the rebel-held oil port of Brega on Thursday, a day after anti-government fighters turned back an assault by forces loyal to the country’s longtime leader Moammar Gadhafi.

    Al Arabiya TV reported that at least one plane bombed a civilian neighborhood in Ajdabiya, a rebel stronghold closer to the rebel-controlled major city of Benghazi.
    Witnesses say an ti-government forces captured nearly a dozen mercenaries from sub-Saharan Africa and East Asia after clashes around Brega. The mercenaries are reportedly fighting alongside Gadhafi loyalists.
