Libya has rejected a warrant issued by the International Criminal Court, ICC, for the arrest of Col Muammar Gaddafi saying that the tribunal has no authority. The ICC earlier accused the Libyan leader of crimes against humanity. It said the court had grounds to believe he had ordered attacks on civilians during Libya's four-month uprising. The Hague-based court also issued warrants for two of Col Gaddafi's top aides – his son Saif al-Islam and intelligence chief Abdullah al-Sanussi. Thousands of people are believed to have been killed in the conflict. Anti-Gaddafi forces said yesterday that they had launched a new push towards Tripoli, with heavy fighting near the strategic town of Bir al-Ghanam to the south-west of capital. The rebel Defence Minister told BBC that forces opposed to Col Gaddafi may also make a move on the capital from the east. Libya's Justice Minister said Libya did not accept the ICC's decision to call for Col Gaddafi's arrest.
