Protests continued on Sunday night in Saudi's Eastern Province for the second day in a row following the death of 18-year old Hussain Yousef al-Qallaf on Friday.
Protesters staged an overnight rally in Tarout Island and marched to denounce the death of al-Qallaf, who died of his injuries after he was allegedly shot in the chest by a police officer. A policeman, Hussein Zabani, was also killed in the clashes on Friday.
Activists shared a video reportedly showing the demonstration on Tarout Island.
Early July, activists accused Saudi forces of killing two demonstrators during an anti-regime protest. The victims were identified as Akbar Hassan Shakhouri and Mohammed redha Felfel.
The blog EA worldview notes that the presence of Bahrain flags and February 14th iconography at last night's protest are notable, and suggest a growing sense of shared purpose between protesters in both countries.
The oil-producing eastern province, where live about 2 millions Shiite Muslims, which also constitute the majority of the population in Bahrain, has been experiencing turmoil since March 2011. They demand the end of discrimination against the Shiite community and the release of political prisoners.
