Baz Mohammed Ghul Mohammed was found guilty of attempting to smuggle a “large amount of heroin” by hiding it in his stomach, the ministry said in a statement carried by SPA state news agency.
He was executed in the Eastern Province city of Khobar, the ministry said.
The Gulf state last year beheaded 78 people, according to an AFP count.

He said confessions were obtained under torture.
Rape, murder, apostasy, armed robbery and drug trafficking are all punishable by death under Saudi Arabia’s strict version of Islamic sharia law. -AFP
