Dozens of police deployed ahead of rally planned by the opposition on Friday fired tear gas and stun grenades at demonstrators who attempted to reach the site of the protest, activists say. There were no reports of casualties. Dozens of protesters attempted to walk to Karbabad, a coastal village in the north of the Gulf nation, to attend a sit-in organised by Al-Wefaq, the main opposition group in Bahrain. According to Al-Wefaq, the protest was banned by Bahraini authorities. The reasons for the ban were not known. Pictures posted on Twitter showed riot police running towards protesters and blocking the way to Karbabab. Some demonstrators sitting in front of police forces were also seen doing the victory sign. Another protest organised by the February 14 Youth Coalition took place in Bilad Al Qadeem, a town west of Manama, the capital of Bahrain. Bothe men and women took part in the protest. Bahrain, which is ruled by a Sunni Muslim monarchy and hosts the U.S. Fifth Fleet, has been in turmoil since activists mainly from the majority Shi'ite community began protests in February 2011, inspired by successful uprisings in Egypt and Tunisia. More than a year later, unrest persists with weekly mass rallies by opposition parties and clashes between youth activists and riot police. Photos via @Feb14Media and @AlWefaqEN
