AMMAN (AFP) - Protesters armed with swords, daggers and bats attacked police in the Jordanian city of Zarqa on Friday, wounding 51 of them, as 32 other police suffered from tear gas inhalation, the country's police chief said. Lieutenant General Hussein Majali told a news conference that "51 policemen, including senior officers, were stabbed with knives, beaten with bats or hit with sharp tools, while 32 other policemen were treated for tear gas inhalation." He said "eight civilians were also hurt when police fired tear gas and tried to stop Salafist demonstrators from attacking shoppers in Zarqa," adding that 17 protesters were arrested and that police are searching for more people. "It was clear that the demonstrators had plans to clash with police. They carried swords and daggers and were provocative, seeking to drag police into a bloody confrontation." Earlier, police spokesman Lieutenant Colonel Mohammad Khatib told AFP six officers stabbed in the clashes were "in serious condition." He said police "had to fire tear gas after a group of Salafists attacked some citizens ... accusing them of being atheists." The Salafists have been demonstrating over the past few weeks to demand the release of 90 prisoners, including Abu Mohammed al-Maqdessi, the onetime mentor of slain Al-Qaeda in Iraq leader Abu Musab al-Zarqawi. Zarqawi, who hailed from Zarqa in the country's north, was killed in an air strike northeast of Baghdad in 2006. The group has also called for the release of Mohammad Shalabi, better known as Abu Sayyaf, who was convicted on terrorism charges following riots in the restive southern city of Maan in 2002. The Salafists espouse an austere form of Sunnis that seeks a return to practices that were common in the early days of the faith. Meanwhile, more than 1,000 people demonstrated in Amman after midday prayers, demanding "regime reforms," Prime Minister Maaruf Bakhit's ouster and the dissolution of parliament. "The people want to reform the regime and eliminate corruption. Jordan is free, Bakhit, get out," demonstrators chanted as they marched from Al-Husseini mosque in the city centre to the nearby city hall. Holding large national flags, the protesters carried banners reading "the people want democracy and social justice" and "we want to dissolve parliament." The demonstration was organised by the powerful Muslim Brotherhood and its political arm, the Islamic Action Front (IAF), as well as leftist and other opposition parties. "The demonstrations will continue until reforms are achieved," Jamil Abu Baker, Brotherhood spokesman, told AFP. "So far, we cannot see any (government) intention to carry out reforms. The people are determined to have real reforms and get rid of corruption." Hundreds of March 24 youth movement members, who were attacked last month by government supporters in clashes that killed one man and injured 160, held a sit-in outside the city hall, calling for general reforms and singing national songs. Around 200 policemen were deployed as dozens of government supporters gathered in the area. Pro-reform demonstrations were held in other, such as Karak and Maan in the south, and Zaraqa and Irbid in the north. On Thursday, the US embassy in Amman told Americans to avoid areas of protests, saying that "even demonstrations intended to be peaceful can turn confrontational and possibly escalate into violence." Jordan has been the scene of three months of protests calling for political and economic reforms as well as the stamping out of corruption.
