A suspected suicide bombing has been reported in the holy city of Madina near Masjid an-Nabawi, Islam’s second holiest site.
Video footage showed a vehicle on fire. There are no details of casualties, though the Saudi Gazette has tweeted that two have died in the explosion.
Saudi-owned al-Arabiya TV also reported a suicide explosion near the security headquarters of the Prophet’s Mosque in Madina.
Earlier, there was an bomb explosion in the eastern city of Qatif, where many minority Shia Muslims reside.
A suspected suicide bomber also died after detonating a device near the US embassy in the city of Jeddah.
The social media footage from Madina showed a vehicle on fire in a car park with two security officers lying nearby.
Some on social media are claiming that a vehicle containing gas cylinders exploded, whilst others are claiming that soldiers have been killed.
It may be the case that images and video footage being circulated on social media of the three separate incidents are getting mixed up.
5Pillars are waiting for a comment from the Saudi Embassy in the UK.
