Moamer Gaddafi threatened on Friday that NATO will face a "catastrophe" if the Western alliance did not stop its strikes on the conflict-ridden country, DPA reported.
"We advise you to retreat before you face a catastrophe," Gaddafi said in a telephone message through Libyan state television, addressing his supporters who gathered in Tripoli's Green Square.
Gaddafi also urged NATO to "hold talks with the Libyan people." He also threatened to attack Europe if NATO does not halt its raids, Al Arabiya broadcaster reported.
The embattled leader vowed to stay on and called on his supporters to head unarmed towards the rebel-held cities of Misurata and Brega.
The International Criminal Court (ICC) issued arrest warrants against Gaddafi, his son Saif al-Islam and his intelligence chief Abdullah al-Senussi for alleged crimes against humanity.
NATO marked 100 days of airstrikes on Libya on Monday. Its nearly 13,000 sorties have helped bolster the rebels, who are now trying to make their way to a showdown in the capital.
The uprising to oust Gaddafi, who has been in power for 42 years, began in mid-February as protests turned into an armed conflict after the government's lethal crackdown on demonstrators.
