The shooting took place during a peaceful protest on Saturday in Karzakan village, which lies along the western coast of the Persian Gulf Islands.
The demonstrators demanded the release of all political prisoners and demanded that King Hamad bin Isa Al Khalifa steps down from power.
At least 13 opposition leaders are held in prison for involvement in protests against the Bahraini regime.
The regime’s courts have handed down life sentences to seven of the activists, including prominent activist Abdulhadi al-Khawaja, and gave the others jail terms ranging from five to 15 years.
Since mid-February 2011, thousands of pro-democracy protesters have staged numerous demonstrations in the streets of Bahrain, calling for the Al Khalifa family to relinquish power.
Following the eruption of the protests, the Bahraini regime promptly launched a brutal crackdown on the peaceful protests and called in Saudi-led Arab forces from neighboring states to assist the suppression.
Dozens of Bahraini people have been killed in the crackdown, and the security forces have arrested hundreds, including doctors and nurses.
Bahrainis say they will continue holding demonstrations until their demand for the establishment of a democratically-elected government is met.
