Some six months of fighting in Libya left a trail of blood and death as rebels overcame forces loyal to Muammar Gaddafi and ended his more than four decade rule.Colonel Hsham Buhagiar, Commander of Anti-Gaddafi troops said, "They say, people say, about 50,000. Yes, Question: Is it possible?Answer: Yes. from both sides. From both sides, yes. I saw, in a picture, a graveyard, in Misrata, with numbers, which has 7,000 people who died, 7,000 graves."Some of the fiercest fighting was in Misrata.Colonel Hsham Buhagiar, Commander of Anti-Gaddafi troops said, "I think Misrata and Zlintan took the most toll. Maybe I would say around 15,000 to 17,000 in that area."The figures include those killed in the fighting between Gaddafi's troops and his foes, and those who have gone missing over the past six months.And the war is not over.Anti-Gaddafi forces gather about 100 kilometers outside Sirte, the hometown of the former Libyan dictator.Libya's interim rulers announced earlier on Tuesday they were setting a four-day deadline for forces loyal to Muammar Gaddafi to surrender or face military force.Anti-Gaddafi forces have converged on Sirte from east and west, but have stopped short of an all-out assault in hopes of arranging a negotiated surrender of Gaddafi's birth-place.Gaddafi's whereabouts have been unknown since his foes seized his Tripoli compound on Aug. 23.
