Authorities say an unidentified man jumped into the personal car of Nigeria's former President Olusegun Obasanjo and punched him.
Airport police commissioner Chris Ola says the attack happened Monday morning at Lagos' busy Murtala Muhammed International Airport. Ola says the man, who is in his 40s, jumped into the president's car as he left the airport's international terminal.
It was immediately unclear if 73-year-old Obasanjo suffered any injury in the assault. Ola on Tuesday described the incident as "a breach of security." Authorities believe it was a spontaneous attack.
Obasanjo served as Nigeria's first civilian president as the nation emerged from a series of military dictatorships and coups, serving from 1999 to 2007.
