Blast hits mosque in southwestern Saudi city
A suspect was injured in Monday's explosion in the country's southwest, Saudi's Al-Ikhbariya channel said.
The interior ministry confirmed a blast had occurred but had no immediate details.
"A person went to the mosque and did an explosion," a spokesman told the AFP news agency.
The television report did not specify whether the mosque belonged to the kingdom's Sunni majority or the Shia minority.
About half of Najran's population belongs to the Shia community.
Most of Saudi Arabia's Shia live in Eastern Province, where they have been targeted four times in the past year by bombings and shootings claimed by the Islamic State of Iraq and the Levant group.
