The president of Senegal has denounced the execution of two Senegalese citizens who were among nine prisoners killed by firing squad in neighboring Gambia last week.

President Macky Sall told reporters at the airport late Tuesday that he was calling on Gambia's leader "to return to reason," referring to his decision to have all death row prisoners executed before the end of September

On Wednesday, a statement published on the Senegalese government website stated the Senegalese prime minister summoned the top Gambian diplomat in Senegal. The statement says the prime minister made known his "deep reproach," calling the events leading to the executions "opaque."

The Gambian government acknowledged this week that it had executed nine prisoners, among them two Senegalese nationals, a woman, Tabara Samb, and a man, Djibril Ba.
