In Sirte, home town of deposed Libyan leader Muammar Gaddafi, his loyalists have been given four days to surrender.
Giving the ultimatum at a press conference on Tuesday, Mustafa Abdul Jalil, the head of Libya's National Transitional Council said: "By Saturday, if there are no peaceful indications for implementing this, we will decide this matter militarily.
"We do not wish to do so but we cannot wait longer."
