A senior U.S. official warned Thursday there was a "very real danger" that Libyan leader Moammar Gadhafi could return to terrorism if he is allowed to consolidate his control over the fractured nation.

There is "a very real danger that if Gadhafi is successful on the ground, that you also face a number of considerable risks as well, the dangers of him returning to terrorism and violent extremism himself," under secretary of state for political affairs William Burns told U.S. senators.

NATO's chief urged the U.N. on Thursday to quickly act on Libya to stop Moammar Gadhafi from crushing rebels, but the alliance was divided even as it pressed ahead with plans for a no-fly zone.

"If Gadhafi prevails it will send a clear signal that violence pays. That would be unacceptable from a humanitarian and democratic perspective," Secretary General Anders Fogh Rasmussen said.

The Libyan army announced that it would halt military operations from Sunday to give rebels the chance to lay down their arms and benefit from an amnesty, state news agency Jana reported Thursday.

Libyan leader Moammar Gadhafi said his forces would fight a "decisive battle" Thursday, as Washington added its voice to efforts at the U.N. Security Council to impose a no-fly zone.
