Saudi Arabia on Saturday identified the suicide bomber who killed 21 worshippers at a mosque for the minority Shiite community and confirmed his link to the Daesh group.

"His name was Salih bin Abdulrahman Salih al-Ghishaami, a Saudi national. He was wanted by security services for belonging to a terrorist cell receiving directions from Daesh abroad," the interior ministry said in a statement carried by the official Saudi Press Agency.
