CAIRO, July 13 (Reuters) - Islamic State has claimed responsibility for Sunday's attack on a security checkpoint in Saudi Arabia, the group's online publication said on Friday.
A Saudi security force member and a foreigner were killed in the attack in Buraidah, a city in Qassim Province north of the capital Riyadh, the Saudi Press Agency said on Sunday.
Islamic State said in its Al-Naba newspaper that three of its fighters were killed in an attack on police forces in Buraidah. It did not provide evidence to support its claim.
Qassim, a heartland of the kingdom's ultra-conservative Wahhabi school of Sunni Islam, is one of the most conservative pockets of the country. (Reporting by Mohamed El-Sherif Editing by Darren Schuettler)
