Libya's National Transition Council fighters met strong resistance Sunday in two of Moammar Gadhafi's remaining strongholds, as NTC leaders delayed announcing a new government.

The NTC had planned to announce Cabinet positions at a news conference, but NTC representative Mahmoud Jibril told reporters last-minute negotiations have delayed the announcement “indefinitely.”

Pro-Gadhafi forces in the desert town of Bani Walid fought NTC fighters with heavy mortar and sniper fire. NTC fighters entering the town from the north answered back with machine gun fire.

Rockets also flew over NTC fighters advancing on Gadhafi loyalists in the former leader's hometown, Sirte. Officials say recent fighting there has killed at least 10 and wounded at least 40 others.

The deposed leader's spokesman, Moussa Ibrahim, says Gadhafi loyalists have the ability to continue the fight “for months.”

NTC fighters returned to the desert town of Bani Walid on Saturday, after loyalists had forced them to retreat a day before.

Turkey has announced it is parachuting 22 tons of humanitarian aid into Bani Walid. The government in Ankara said Saturday the aid is for civilians who are in urgent need of help.
