Bahrainis have held fresh demonstrations across the country, calling for an end to the Al Khalifa rule in the Persian Gulf kingdom.
The protests, dubbed Pride and Disobedience, were held in several towns and villages near the capital, Manama, on Thursday.
The protesters chanted slogans against the ruling Al Khalifa family. They also called for the release of jailed opposition leaders.
The demonstration in the town of Daih turned violent after regime forces attacked the protesters with tear gas.
The uprising in Bahrain began in mid-February 2011. Protesters initially called for political reforms and a constitutional monarchy. However, the demand later changed to an outright call for the ouster of the Al Khalifa family following its brutal crackdown on popular protests.
On March 14, 2011, troops from Saudi Arabia and the United Arab Emirates were called in to assist the Bahraini regime in its crackdown on the peaceful protests.
Scores of people have been killed in the crackdown, and security forces have arrested hundreds, including doctors and nurses. Dozens of demonstrators have also been sentenced to jail terms for attending street protests.
Physicians for Human Rights says doctors and nurses have been detained, tortured, or have disappeared because they have “evidence of atrocities committed by the authorities, security forces, and riot police” in the crackdown.
