Islamic State not significant threat in Saudi Arabia: US military

Washington: Islamic State is not a significant threat in Saudi Arabia, the US military said on Friday, as it declined to speculate on the Sunni militant group`s claim of responsibility for a deadly bombing at Shi`ite Muslim mosque.

"In terms of Saudi Arabia and (Islamic State), we have no indication that they pose a significant threat at this time," said Colonel Patrick Ryder, a spokesman for the Pentagon`s Central Command, which oversees US forces in the Middle East.

Friday`s blast killed four people and was the second attack claimed by the Sunni militant group in a week in the world`s top oil-exporting country.
