A decision
to evacuate as violence in the Libyan capital grows is "minute by minute,
hour by hour," a defense official told CNN on Monday.
Fierce
fighting swept across the city Sunday after armed men stormed the country's
interim Parliament. Sporadic bursts of gunfire and blasts could still be heard
on the outskirts of the capital Monday evening.
The
violence appeared to be some of the worst since the 2011 revolution that ousted
longtime leader Moammar Gadhafi.
