At least 20 Umrah pilgrims died and 29 were injured on Monday in a bus accident in southern Saudi Arabia.
Local media has reported that the pilgrims, all of the different nationalities, were heading towards Masjid ul Haram in Mecca to perform Umrah.
The accident, which occurred as a result of brake failure, took place on a road linking Asir province and the city of Abha.

In a statement released on Tuesday, he commiserated with the bereaved families and prayed for the departed souls.
Saudi civil defence and Red Crescent Authority teams rushed to the site of the accident and cordoned off the area.
