Supporters of Libyan leader Muammar Gaddafi attacked UN Secretary General Ban Ki-Moon in Cairo on Monday, the Agence France Presse news agency reported.
Ban was attacked by protesters angry about the UN's military intervention in Libya as he left a meeting of the Arab League on Cairo's Tahrir Square.
The UN leader was forced to return to the Arab League building and was reported to have left by car from another exit.
Tahrir Square was the focus of a popular uprising that overthrew President Hosni Mubarak last month.
The attack comes just three days after the UN adopted a resolution to impose a no-fly zone and "all necessary measures" against Gaddafi's forces.
Countries including the United States, Britain and France launched on Monday a second wave of air strikes on the positions of Gaddafi's forces in a bid to protect civilians caught up in a month-long civil war in Libya.
