It was in the Lebanese national league, which is probably the best in Asia, and they never have scores like that, usually.
The special circumstances for this game were, as far as I have gathered from comments on FIBAs facebook page, as follows:
The opposing team is in financial troubles (probably going bankrupt) and will be thrown out of the league. The team decided to throw this game by using only bench players and not play any real defense. Soon Akarri just stood on the front court catching passes and shooting. His coach kept him in for the entire game, probably to let him have this record.
Lebanon has a very good national team, and has qualified for the FIBA World Cup for the last three tournaments. Akarri has never been called up.
