MANAMA, Bahrain (AP) — Explosions targeted police in Bahrain on Friday as clashes between security forces and anti-government protesters on the third anniversary of the Gulf nation's uprising left dozens wounded, authorities and activists said.
Efforts to restart on-and-off reconciliation talks between the Shiite-dominated opposition and the Sunni monarchy and its allies have so far failed to bring an end to simmering unrest in the country, an American ally that hosts the U.S. Navy's 5th Fleet.
Activists frequently clash with police in mainly Shiite villages just beyond the modern skyscrapers and shopping malls of the capital, Manama. Tensions intensified as the anniversary of the Arab Spring-inspired uprising approached, with government forces tightening security and activists blocking roads to Shiite communities with oil slicks and smoldering debris.
Mohammed al-Maskati, the president of the Bahrain Youth Society for Human Rights, said his group recorded 38 protesters injured in clashes since Thursday evening. The injuries were caused by birdshot fire, tear gas and beatings, he said.
Government forces also reported casualties. An explosion struck a minibus carrying police Friday evening in Dih, the Ministry of Interior said on its official Twitter feed. Dih is a mainly Shiite village just west of the capital, Manama.
Photos released on the ministry's Twitter feed showed the side panels of the white bus torn from the chassis and twisted upward near the wheel wells.
A ministry official near the scene of the blast told reporters that three police officers were injured in the explosion. He insisted on anonymity because he was not authorized to speak publicly.
Another explosion injured two police officers in Dair, near the country's main airport, according to the Interior Ministry.
Anti-government factions have been increasingly using bombs targeting government forces, though they typically do not have the force of explosives used by insurgents in places such as Iraq or Syria. Authorities in late December announced the seizure of large amounts of explosives, automatic rifles and ammunition.
Earlier in the day, protesters were turned back by tear gas and stun grenades as they tried to make their way to the former site of Manama's Pearl Square, the focal point for the protest movement that started on February 14, 2011. The square was cleared by police raids and later razed in the early weeks of the unrest and is now sealed off by security forces.
Some of the youths marching Friday were seen carrying Bahraini flags, while others were masked and held unlit Molotov cocktails or metal rods. Police used tear gas to prevent them from approaching the former protest grounds.
Opposition groups dominated by the country's majority Shiites began protesting in 2011 to seek greater political rights from the country's rulers. More than 65 people have died in the unrest, but rights groups and others place the death toll higher.
Neighboring Sunni-ruled Gulf countries, led by Saudi Arabia, sent troops to Bahrain to help quell the uprising.
Many activists remain frustrated that too little has been done to meet their demands.
"After three years the government did not achieve anything, only besieging Pearl Square," said Wajiha Ali, a 23-year-old mother of two. "I really want to live in a country that respects me and gives me my full rights. ... The government is not looking for long-term solutions, just security measures."
On Thursday, the eve of the anniversary, 29 were arrested over "rioting and vandalism" in villages outside Manama, the Interior Ministry said.
Roads were blocked, a car was burned by protesters and a school bus carrying children was attacked by "Molotov-throwing thugs," the ministry alleged.
Repeated rounds of political talks have failed to significantly close the rifts between the two sides and the opposition is demanding amnesty for what they claim are more than 3,000 political prisoners held in Bahraini prisons.
Crown Prince Salman bin Hamad Al Khalifa met with top opposition leaders last month to once again revive the talks.
"The government is serious about dialogue and hope all others are also serious," government spokeswoman Sameera Rajab told The Associated Press.
The main Shiite bloc al-Wefaq and other opposition groups see the negotiations as a positive step but have said their success depends on steps toward greater power sharing in the kingdom.
But many activists in the streets have taken a harder line, calling for the toppling of the government and at times clashing violently with police.
"We have nothing to lose. They treat us like animals," said protester Ali Jaber, 19, next to a makeshift roadblock set up using a downed lamp post in Dih earlier this week.
Al-Wefaq head Ali Salman and other opposition leaders have urged followers to rally to an anti-government demonstration scheduled to be held Saturday east of the capital.
The United Nations expressed concern at Bahrain's persistent violence, urging both sides to exercise restraint and authorities to act in strict accordance with their international human rights obligations.
"All Bahrainis should work toward creating a conducive atmosphere for a genuine dialogue in the interest of peace, stability, reform and prosperity for all Bahrainis," U.N. Secretary-General Ban Ki-moon said through a spokesman.
