A suicide bomber killed one worshipper and wounded others on Monday at a mosque in Saudi Arabia's southern Najran city, the interior ministry said.

The attack occurred just after Maghrib early evening prayers at the Al-Mashad mosque in Najran's Dahza neighborhood, the ministry said in a statement.

"As worshippers were leaving the mosque, a person wearing a suicide belt entered and blew himself up amongst them," it said, describing the incident as "a terrorist crime".

The wounded were taken to hospital, the ministry said without giving a number or more details.

Al-Ekhbariya Saudi news channel earlier reported that, in addition to one person killed, 12 people were wounded, as was the suspect.

Residents of Saudi Arabia's Eastern Province have been targeted four times in the past year by bombings and shootings linked to the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group.

The latest attack in the east occurred on October 16 when a gunman fired on gathering of people commemorating Ashura in the Qatif area, before police shot him dead.

Ashura is one of the holiest occasions for the Shiite faith, during which faithful people commemorate the holy martyrdom of Imam Hussein (AS) grandson of Prophet Mohammad (PbUH).
