Nigeria, Oct. 28 -- Nobel Laureate Wole Soyinka has been barred from entering the United States after the government revoked his visa, a move the celebrated playwright said he does not understand.

Speaking at a media briefing on Tuesday at Kongi's Harvest Gallery, Freedom Park, Lagos Island, Mr Soyinka said he was unaware of any action that could have prompted the revocation.

"I have no visa; I am banned, obviously, from the United States. And if you want to see me, you know where to find me," he told journalists, according to The Punch.

He added, "It is necessary for me to hold this conference so that people in the United States who are expecting me for this event or that event do not waste their time."
