A 21-year-old Bahraini youth suffered gunshot wounds and several others sustained minor injuries when anti- riot police and protesters clashed in the Shiite village of Karzakan on Sunday night, dpa reported.
The clashes came on the eve of expected "Day of Wrath" protests organized online to demand reforms and more freedoms. The planned protests Monday are expected to be similar to those that have rocked the broader Middle East in recent weeks.
The youth was said to be in a stable condition with non-life threatening injuries.
Police fired rubber rounds and tear-gas at wedding-goers inside a religious community hall, after protesters allegedly mixed with those in attendance to evade police. The partygoers had refused to disperse before police opened fire, witnesses said.
The Bahraini Ministry of Interior said three police officers had been attacked after what they called an "illegal rally" in the village. Police fired two warning rounds, one of which bounced off the ground and hit a demonstrator.
Monday's expected protests coincide with the country's 10th anniversary of the National Charter vote that ended the unrest of the 1990s, paved the way for the reintroduction of parliamentary life and brought an end to state-emergency laws.
The leading Shiite Islamic opposition group, al-Wefaq, has come out in support of some of the demands and the right to demonstrate. They have not, however, specifically support the planned protest, while other opposition groups are supporting the demonstrations.
The Sunni Salafist al-Asalah Islamic Movement has warned of the dangers of protesting.
The country was visibly on heightened alert on Sunday with strong police presence across the small Gulf island, practically around Shiite villages and key infrastructure.
