Bahraini protesters have taken to the streets to demand the overthrow of the ruling Al Khalifa regime.
The new demonstrations were held on Sunday to mark a year since a teenage protester was shot dead by Manama regime forces.
The 14-year-old Ali Jawad al-Sheikh was killed at a mosque while attending religious ceremonies on the occasion of Eid al-Fitr, which marks the end of the fasting month of Ramadan.
The protesters also called on the Bahraini authorities to release all the prisoners jailed over participating in demonstrations.
Since mid-February 2011, thousands of protesters have held numerous demonstrations in the streets of Bahrain, calling for the Al Khalifa royal family to relinquish power.
On March 14, 2011, troops from Saudi Arabia and the United Arab Emirates were deployed to assist the Bahraini government in its crackdown on peaceful protesters. The crackdown also left scores of people dead.
Manama has imprisoned thousands of people for attending demonstrations over the past three years.
Human rights groups have voiced concern over the treatment of the Bahraini activists kept in prisons and the atrocities committed by authorities and security forces in the government crackdown.
