The United States has launched a diplomatic offensive against Libya among African nations as Tripoli accused NATO of a "massacre" of 85 villagers in air strikes in support of rebels.
Meanwhile, Libyan state television broadcast images of a man it says is Muammar Gaddafi's youngest son, footage that looks to undercut rebel claims of his death at a time when the opposition is showing signs of strain and disarray six months into its battle with the Libyan leader.
American diplomats are visiting several African countries as part of efforts to urge leaders to press Muammar Gaddafi to leave power immediately, officials in Washington said on Tuesday.
