Saudi Arabia blames protests on 'outside forces'

Saudi Arabia has blamed an unnamed foreign power for clashes that took place in its oil-rich Eastern Province in which it says 14 people were injured.

The unrest, on Monday night, occurred in the Gulf coast city of Qatif, which is home to a large Shia population and was the scene of protests earlier this year.

"A foreign country is trying to undermine national security by inciting strife in Qatif," Saudi state television cited the interior ministry as saying on Tuesday.
