WASHINGTON, Aug 23: Some of the people attacking US forces in Iraq are slipping across the border from Saudi Arabia, US Deputy Secretary of State Richard Armitage alleged in a television interview on Friday.

US officials have long alleged some militants have come through Iran and Syria and have warned both against interference in Iraq, but have not previously singled out Saudi Arabia.

“The borders are quite porous, as you’d imagine, and the fact that we’ve captured a certain number of foreign fighters in Baghdad and around Iraq indicates that the ways that these people are getting into the country is from Iran and from Syria and from Saudi Arabia,” Mr Armitage said in an interview with the Al Jazeera television network.—Reuters
