Saudi Arabia arrests 'IS militant' accused of killing officer
An interior ministry spokesman said the assailant was captured three days after shooting dead soldier Abdullah al-Rashidi on Sunday in the northwestern city of Tabuk.
"The culprit confessed to adopting the doctrine of terrorist [group] Daesh [IS]," the spokesman said in a statement carried by SPA state news agency.
The man, identified as Hayel al-Atawi, said he "committed the crime in response to a call by the [IS] organisation to target military personnel", the statement added.
Seven others were arrested in relation to the killing, it said.
IS leader Abu Bakr al-Baghdadi has called for attacks against Saudi Arabia, which belongs to a US-led coalition battling the IS in Syria and Iraq.
Since late 2014 IS has claimed a series of bombings and shootings targeting Shias in the Sunni-majority kingdom, as well as the security forces.
