A published report says Zimbabwe security officials are probing whether two cabinet officials and a lawmaker are linked to an alleged spying ring.
The state-run Sunday Mail reports officials this week hope to question the three men, who have been accused of passing state secrets to foreign intelligence agencies.
The report alleges the men received "handsome payments" for the information.
Another person suspected in the alleged ring is an official, Erasmus Moyo, at Zimbabwe's embassy in Geneva, who has been reported missing. Officials say he disappeared after being summoned back to Zimbabwe.
Last month, police arrested four other men, including a ruling party lawmaker, Philip Chiyangwa, on charges of selling state secrets to foreign powers.
