The anti-regime demonstrations were held in several districts, including Musalla on the western outskirts of the capital city, Manama, on Monday, according to a report by al-Wefaq’s Arabic-language website.
The Bahraini protesters called for the immediate release of political prisoners, Sheikh Salman in particular.
They also urged the al Khalifa regime to end the trial of the prominent Shiite cleric and clear him of the “irrational charges”.
Sheikh Salman was arrested in late December 2014 over alleged anti-regime incitements. Manama accused him of seeking regime change and collaborating with foreign powers.
Bahrain, a staunch ally of the United States in the Persian Gulf region, has been witnessing almost daily protests against the ruling Al Khalifa dynasty since early 2011, with Manama using heavy-handed measures in an attempt to crush the demonstrations.
Scores of Bahrainis have been killed and hundreds of others injured and arrested in the ongoing crackdown on the peaceful demonstrations.
