Mourners take part in a mass funeral held on June 3, 2015, in the coastal Saudi city of Dammam, for the victims of a mosque bombing carried out by the Islamic State (IS) group. While thousands gathered to mourn the four victims, the interior ministry released a list of 16 men suspected of involvement in the suicide blasts. It promised rewards of up to five million riyals ($1.33 million) for help in catching them. AFP PHOTO / STR
