Yadh: At least three people were killed and 12 others injured on Monday after a suicide bomber targeted worshipers who were exiting a mosque after finishing their prayers in Saudi Arabia's southern Najran region bordering Yemen, state television reported.
"One person killed in Najran mosque bombing, 12 injured and the suspect is injured," Al Arabiya News Channel reported.
As per the initial reports, the attacker targeted the worshipers inside al-Mashhad mosque in the southwestern city but the Saudi interior ministry said the incident took place at the courtyard of the mosque.
Further information about the perpetrators behind the deadly incident was not given.
This is not the first time mosques have been targeted by bombers in the kingdom.
In mid-October, five people were killed after a gunman opened fire on a Shiite Muslim meeting hall in the Eastern city of Saihat.
In August, at least 12 security officers were killed after a suicide bombing targeted a mosque used by special forces in the southern Saudi city of Abha.
The Islamic State of Iraq and Syria (ISIS) militant group claimed responsibility for two separate attacks which took place in May and August.
The militant group has also targeted Shiite mosques and places in other regional countries including Kuwait and Iraq in attempt to create sectarian strife.
