According to the al-Salbaq news website,13 people including women and children died and 36 others were injured.
The accident took place on a road connecting the Saudi cities of Riyadh and Taif, as the bus was transporting 49 passengers of different nationalities who were performing the Umrah, the minor Muslim pilgrimage to Mecca.
As per the local officials reports and initial investigations showed that the accident happened due to the bursting of the front tyre of the bus.
Unlike the Hajj pilgrimage, Umrah can be performed at any time of the year but it is highly popular during the Muslim holy month of Ramadan.
