“Saudi Arabia has arrested 431 people suspected of belonging to Islamic State cells and thwarted attacks on mosques, security forces and a diplomatic mission, the interior ministry said on Saturday. The announcement came after a car bomb exploded at a checkpoint near the kingdom’s highest security prison on Thursday, killing the driver and wounding two security officials in an attack claimed by Islamic State.”
