Interpol has issued red notices for the arrest of the former Libyan leader Muammar Gaddafi, his son Seif al-Islam and the country's ex-head of military intelligence, Abdullah al-Senussi.
The move comes in response to a request by the prosecutor of the International Criminal Court, which is seeking the men for alleged crimes against humanity.
Gaddafi hasn't been seen in public for months and went underground after anti-regime fighters swept into Tripoli on August 21.
Interpol said it had transmitted the red notices to its 188 member countries.
The head of the organisation, Ronald Nobel, called the notices "a powerful tool" in helping lead to the capture of the Gaddafis and al-Senussi.
