President Muhammadu Buhari’s scheduled one-day visit to Ogoni land, Rivers State, Nigeria for the flag-off of the Ogoni land clean up has been cancelled.

The President will now be represented by Vice President Yemi Osinbajo at the event.

No reason has been given for the cancellation.

The oil-producing Niger Delta has been hit by a wave of militant attacks in recent weeks.

President Muhammadu Buhari had been expected to launch the activities for the clean-up of the oil impacted Ogoni land on Thursday, June 2, 2016.
