SIRTE, Libya – With NATO jets roaring overhead, revolutionary forces fought their way into Moammar Gadhafi’s hometown Saturday in the first significant push into the stubborn stronghold in about a week.

Libya’s new leaders also tried to move on the political front, promising to announce in the coming week a new interim government that they hope will help unite the country. However, disagreements remain about what the Cabinet should look like.

The National Transitional Council led the rebellion that forced Gadhafi into hiding and has taken over the leadership of the oil-rich North African nation even as it continues to fight forces still loyal to the fugitive leader.

The NTC-appointed prime minister, Mahmoud Jibril, sought support from leaders at the United Nations on Saturday, telling them that “a new Libya is coming to life” as a nation committed to democracy, equality and reintegration into the international community. He said the council was committed to drafting a constitution that would be put to referendum.
