Outrage spreads after 3 attacks in one day in Saudi

Outrage spread on Tuesday after a deadly suicide bombing at Islam's second-holiest site in the Saudi city of Medina, one of three attacks in the kingdom on a single day.

Religious and political leaders across the Middle East denounced the attack near the Prophet's Mosque that left four dead and came as Muslims prepare for the feast this week marking the end of the holy month Ramadan.

There were no claims of responsibility for Monday's bombings in Medina, Jeddah and the eastern city of Qatif, but the Islamic State group (ISIS) had urged its supporters to carry out attacks during Ramadan.

The jihadist group has claimed or been blamed for a wave of shootings and bombings during the holy month this year, including in Orlando, Bangladesh, Istanbul and Baghdad.
