Libya's opposition Transitional National Council has announced a four-day deadline for forces loyal to Moammar Gadhafi in his hometown of Sirte to surrender.
TNC leader Mustafa Abdel Jalil said Tuesday in the rebel-stronghold of Benghazi that rebels will resort to military action in Sirte if they get no indication by Saturday of a peaceful end to the conflict there. Rebels say they are bracing for a final battle to gain control of most of their country.
Mr. Gadhafi has not been seen since rebel fighters seized the capital, Tripoli, last week, and Sirte is considered one area where he may be hiding.
Rebel forces have drawn closer to Sirte and NATO has carried out airstrikes against radar sites, missile systems and armed vehicles.
NATO's Colonel Roland Lavoie told reporters Tuesday the alliance is aware of negotiations going on between pro- and anti-Gadhafi forces in Mr. Gadhafi's hometown.
He said Mr. Gadhafi remains a “global threat” and “continues to threaten the overall population of Libya.” He added that Mr. Gadhafi still displays the ability to command and control military forces and weapons and has shown “no intent to retreat peacefully and call his forces off hostilities.”
In Algeria, government officials say Mr. Gadhafi's daughter, Aisha, gave birth to a girl on Tuesday, a day after the country allowed members of Mr. Gadhafi's family to cross the Libyan-Algerian border.
The Algerian Foreign Ministry announced that Mr. Gadhafi's wife Safiya, daughter Aisha, and two of his sons, Mohammad and Hannibal, all crossed into the country by car. They said the spouses of the Libyan leader's children and their offspring also crossed into Algeria.
Rebel leaders in Libya have demanded authorities in Algeria extradite members of Libyan leader Moammar Gadhafi's family.
Also on Tuesday, a U.S. human rights group says it has uncovered evidence of possible war crimes by pro-Gadhafi forces in Misrata.
Physicians for Human Rights said in a report that forces loyal to Mr. Gadhafi carried out murder, torture, rape and forced internment. The report says the troops forced civilians to act as a human shields to guard military munitions from NATO attacks, and blocked civilians from receiving humanitarian aid.
Meanwhile, the World Food Program said Tuesday it is sending 600 metric tons of food to Tripoli along with other urgent supplies, including water, medicine and fuel to help people affected by the fighting. The group says the food will be distributed by the Libyan Red Crescent and help feed 35,000 people for one month.
In Zimbabwe Tuesday, the country expelled the Libyan ambassador and his staff after they claimed allegiance to Libya's TNC. Zimbabwean President Robert Mugabe is a strong ally of Mr. Gadhafi, and Zimbabwe has not recognized the TNC as the legitimate representative of the Libyan people.
