A gunman shot dead five people at a Shia gathering in eastern Saudi Arabia on Friday before police shot him dead, the interior ministry said.
A group claiming affiliation with the Islamic State (IS) group said it carried out the attack.
“As result of his shooting, five citizens … were killed, including a woman. Nine others were wounded,” an interior ministry spokesman said in a statement.
He said that at about 7:00 pm (1600 GMT) on Friday a suspect with an automatic weapon “started to shoot randomly” at al-Haidaria hussainiya in the Saihat area of Qatif city.
Police intervened and opened fire, killing the suspect, the spokesman said without giving details about the attacker.
“The situation is still under investigation,” he said.
A group calling itself Islamic State-Bahrain State said in a statement that one of its “soldiers,” Shughaa al-Dosari, “attacked a Shia infidel temple with an automatic weapon” in Saihat.
It said: “infidels will not be safe in the island of Mohammed”.
The shooting, in the Qatif area of Eastern Province, came two days after the start of commemorations of Ashura, one of the holiest occasions for the Shia faith, a minority in Sunni-dominated Saudi Arabia.
During Ashura last year, gunmen killed seven Shia worshippers, including children, in the eastern town of al-Dalwa.
The interior ministry said the suspects in that unprecedented attack were linked to the IS group.
A witness to Friday’s attack, Ali al-Bahrani, told AFP that “a gunman began randomly shooting at people attending a sermon”.
Since the start of Ashura commemorations Shia security volunteers had been checking people trying to enter houses of worship, Nemr said.
Security has been tightened at Shiite facilities since May when separate suicide mosque bombings killed 25 people.
Both attacks were claimed by IS, a hardline armed Sunni group that considers Shia Muslims to be heretics.
Later on Friday, Shia Saudis held a protest march in Saihat condemning the attack.
