Six people have been arrested in connection with the shooting attack in Saudi Arabia yesterday, in which at least five people were killed, state news agency SPA said.

Gunmen shot dead five people in Al-Dalwah village of Al Ahsa district in the Eastern Province.

"As a group of citizens was leaving a building ... three masked men opened fire at them with machine guns and pistols," the spokesman said, according to SPA, adding that the incident was under investigation.

It gave no further details.

In Riyadh, an official council of top Sunni Muslim scholars condemned the attack as a "vicious assault and a heinous crime whose perpetrators deserve the harshest religious penalties."

Separately, Saudi-owned Al-Arabiya television reported that a wanted man and a member of the security forces were killed in "security clashes" north of the capital Riyadh. It was not immediately clear if the incident was linked to the shooting in Al-Ahsa. - Reuters
