Saudi security forces killed a gunman on Saturday morning after he fired at a checkpoint near the Interior Minister's palace in Jeddah, the state news agency said.

Police said they were unable to confirm whether the incident was terror related.

'At 1 a.m. on Saturday, a person carrying a gun fired at a checkpoint in Abdulrahman Al-Malki Street in Jeddah. He was dealt with swiftly and was killed. The event is still under investigation,' the SPA statement said. 

There were no other deaths or casualties, the statement said.

Around the same time two years ago the Interior Minister's son, Prince Mohammed bin Nayef Al-Saud, who oversees the country's counter-terrorism programme, survived an attempt on his life by a suicide bomber posing as a repentant militant.

Interior Ministry spokesperson Mansour Al-Turki referred a call for comment to Jeddah police spokesperson Mesfer Aljoayed, who was not immediately available.

Police First Lieutenant Nawaf Nasser said he could not confirm if the incident was a terror attack and added: 'There is an investigation on-going. It is not complete yet and there will be a final statement once it is.' – Reuters
