(CNN) - Libya on Friday called for international observers to come and verify a cease-fire that witnesses say has failed to halt deadly fighting.
One day after the approval of a U.N. Security Council resolution authorizing the use of force to protect civilians, U.S. President Barack Obama warned Moammar Gadhafi to pull back from several besieged cities or face military consequences.
But Obama insisted that American troops will not be deployed in Libya.
At least 28 people died and hundreds were wounded as fighting raged in the cities of Mistrata, Ajdabiya and Zintan on Friday, according to Khaled el-Sayeh, military spokesman for the opposition.
