Top United Nations officials have expressed deep dismay and regret over yesterday's executions by Saudi Arabia of 47 people, including the cleric Sheikh Nimr Baqir al-Nimr, and called on the country's authorities to commute all death sentences. "Sheik al-Nimr and a number of the other prisoners executed had been convicted following trials that raised serious concerns over the nature of the charges and the fairness of the process," Secretary-General Ban Ki-moon's spokesperson said yesterday in a statement, also deploring violence by demonstrators against the Saudi embassy in Tehran. "The Secretary-General reiterates his strong stance against the death penalty," it added, noting that Mr. Ban had raised the case of Sheikh al-Nimr with Saudi leaders on a number of occasions. "He points to the growing movement in the international community for the abolition of capital punishment and urges Saudi Arabia to commute all death sentences imposed in the Kingdom," the statement noted. Mr. Ban called for calm and restraint in reaction to the execution of Sheikh Nimr and urged all regional leaders to work to avoid exacerbating sectarian tensions.
