At least three people have been killed in a mosque attack in Saudi Arabia's eastern governate of al-Ahsa on Friday, Al Arabiya News Channel reported.

A suspect in the attack has been reportedly arrested, sources said.

Eastern regions of Saudi Arabia have been on alert after ISIS claimed two attacks Shia mosques last year.

In August, a suicide bomber killed at least 15 people in an attack on a mosque used by members of a local security force in southwest Saudi Arabia. In May, a suicide bomber blew himself up during Friday prayers at a mosque in the village of al-Qadeeh in eastern Saudi Arabia, killing at least 21 and wounding 81 others.
