A court in Johannesburg has convicted Nigerian militant Henry Okah of 13 terrorism counts, over a car bombing in Abuja in 2010.
Okah pleaded not guilty to the charges and denied being the leader of the militant group Mend, which claimed responsibility at the time.
Johannesburg High Court Judge Neels Claassen said "I have come to the conclusion that the state proved beyond reasonable doubt the guilt of the accused,"
South African prosecutor Shaun Abrahams told AP that Okah is likely to face life imprisonment.
He said South Africa worked closely with foreign law enforcement agencies "to make sure justice is done in Africa,"
"This [conviction] is clearly indicative that South Africa cannot be seen as a safe haven for international terrorists," Mr Abrahams added.
