Saudi Arabia’s foreign minister said on Thursday the murder of journalist Jamal Khashoggi in its Istanbul consulate is now a legal case and should not be politicized, after the public prosecutor said it would seek the death penalty for five suspects, Reuters reported.

“The politicization of the issue contributes to a fissure in the Islamic world while the kingdom seeks the unity of the Islamic world,” Adel al-Jubeir told reporters in Riyadh.

Jubeir added that there were still unanswered questions in need of answers, but Ankara had refused three requests from Riyadh to provide proof of their accounts of the killing.
