Bab El Ehr is a gun smuggling commander, and enemy and the planning dictator of Khemed of Emir Mohammed ben Kalish Ezab.
He first appears in Land of Black Gold when Tintin was knocked out by a gas bomb and his men brought him to their campsite. Bab El Ehr first thought that Tintin had news about his guns, and when Tintin shows that he was not the man he was looking for, he was accused of as a spy, then tied up Tinitn, and marooned him in the desert and is later mentioned in The Red Sea Sharks. Playing a major behind-the-scenes role in the Red Sea Sharks, he forces the Emir to abdicate, resulting in Abdullah being sent to Marlinspike for protection. At the close of The Red Sea Sharks, he is overthrown and potentially executed after the Emir is reinstated. However, it is uncertain whether he died or not.
