A US computer salesperson who supplied ­sensitive equipment to MTN’s mobile network in Iran has been jailed for violating US economic sanctions.

According to an online profile of a man stating that he works for MTN Irancell as an IT operator, his employer, Patco, is MTN Irancell’s IT partner.

The person who leaked the MTN and Turkcell memos has to face the possibility of being implicated in the bribery of Iran government officials’ claims.

Cellphone giant MTN has sought advice in the wake of sanctions by the United States against companies that aid human rights abuses.

A lawsuit filed by Turkcell over a licence in Iran has implicated MTN executives and state officials in an explosive bribery and weapons scandal.
