Manama regime forces have attacked protesters demanding the pullout of Saudi forces from Bahrain.
Amateur footage shows security forces firing tear gas to disperse young demonstrators in the eastern village of Ma’ameer.
Similar demonstrations were held in the villages of Sitra, Hamala and Nuwaidrat.
In Hamala, protesters clashed with security forces after blocking a road with burning tires.
They chanted slogans against the ruling Al Khalifa family and hurled Molotov cocktails at police.
Bahrain has been the scene of street protests since 2011, during which scores of people have been killed and hundreds more detained.
Amnesty International has censured the Manama government for its “relentless repression” of anti-government protesters, blaming Bahraini security forces for their repeated use of “excessive force to quash anti-government protests.”
On February 14, UN Secretary-General Ban Ki-moon called on the Bahraini government to respect its “international human rights obligations” in dealing with peaceful protests in the country.
