The convoy of Gani Fawehinmi, a candidate in next month's presidential election, has been attacked as he returned home after a campaign. He said that the gang of four machete-wielding men asked for him by name but he was in a different car to the one attacked. Mr Fawehinmi, a human-rights-lawyer-turned-politician, is one of 19 challengers to President Olusegun Obasanjo in next month's election but correspondents say he is unlikely to win.
