RIYADH: Saudi Arabia on Thursday carried out its 137th execution this year, putting to death another of its citizens for murder. Mohammed al-Qahtani had been convicted of gunning down a fellow Saudi with an automatic weapon in an argument, the interior ministry said in a statement. Most executions in the kingdom are carried out by beheading with a sword, in what the ministry says is a deterrent. According to AFP tallies, Qahtani was the 137th Saudi or foreigner put to death by the kingdom this year, compared with 87 in 2014. Under the kingdom’s strict Islamic legal code, murder, drug trafficking, armed robbery, rape and apostasy are all punishable by death.
