Despite a heavy government crackdown on protests, Libyan demonstrators are calling for another night of defiance against leader Moammar Gadhafi's regime in Tripoli's main square.

After over 40 years in power, Gadhafi is the Arab world's longest-ruling leader and a strong U.S. ally, despite having no official government function other than the self-proclaimed titles of "Brotherly Leader and Guide of the Revolution" and "King of Kings of Africa."
