MANAMA Formula One world champion Sebastian Vettel won the Grand Prix in Bahrain on Sunday while rage boiled beyond the circuit among protesters who say the ruling family that crushed Arab Spring demonstrations last year should not have hosted the race.
High security kept trouble well away from the track, where Red Bull's Vettel had started in pole position in a race that passed without incident before half-empty stands.
Demonstrators said the nightly violence outside the capital Manama over the past week showed the authorities' determination to go ahead with the competition this year was a mistake.
"They miscalculated. They thought cancelling the race would be a defeat for them but they didn't realise the cost of holding the race," Shi'ite activist Alaa Shehabi said by telephone.
"They didn't factor in the negative branding."
Thousands of people took to the streets in pro-democracy protests in the Shi'ite villages dotted around Manama this weekend and demonstrators have hurled petrol bombs at security forces who responded with teargas, rubber bullets and birdshot.
The luxury sporting event was the government's chance to show life was back to normal in the island kingdom after security concerns over anti-government demonstrations forced last year's race to be delayed, then cancelled.
But many of seats in the grandstand and other areas were empty - despite lavish entertainment at the event to attract punters. Officials put spectator numbers at 28,000 in a circuit that can hold 45,000.
Some teams expressed frustration at the attention on politics. Vettel said shortly after arrival on Thursday that he thought much of what was being reported was hype and wanted to focus on "stuff that really matters - tyre temperatures, cars".
After the race, he appeared relieved. "It was a difficult race, extremely tough," said the 24-year-old German, who closed his eyes and took a deep breath as he stood on the podium.
In a dramatic comeback from 11th on the starting grid, Finland's Kimi Raikkonen was second for Lotus with French team mate Romain Grosjean in third place.
Crown Prince Sheikh Salman bin Hamad al-Khalifa, who brought the race to the country in 2004, securing the first Formula One event in the region, smiled and shook hands with other spectators at the finish.
Earlier on Sunday, black smoke from burning tyres wafted over Budaiya, a village outside the capital that saw mass protests this week.
A protester was found dead on Saturday after what opposition activists said was a police beating, infuriating the Shi'ite Muslim majority that complains of marginalisation by the Sunni ruling family and brutality since last year's crackdown.
The funeral of Salah Abbas Habib, 36, could set the stage for more riots, but it was not clear when it would be as authorities have sometimes held on to bodies for days or weeks.
Formula One and Bahraini officials have dismissed suggestions the race should not have been held and for those inside the Grand Prix bubble, far from the scenes of protest, the unrest had little impact.
Teams raced around the Bahrain International Circuit amid the usual security precautions. The highway to the circuit was lined with police cars.
The race is sponsored by a string of global brands. Thomson Reuters, parent company of Reuters, is a sponsor of the Williams Formula One team.
Bahrain, a close military ally of the United States, is the only one of the Gulf monarchies to have been seriously threatened by Arab Spring protests that brought down the rulers of Tunisia, Egypt, Libya and Yemen since the start of 2011.
Its government crushed protests last year, swept demonstrators off the streets and bulldozed the traffic circle where they had camped. Thirty-five people, including security forces, died in that crackdown. Since then, Shi'ite areas have remained volatile and clashes have increased in recent months.
The Bahrain government commissioned an independent inquiry after last year's crackdown and says it is enacting reforms. Human rights groups say it is moving too slowly.
King Hamad bin Isa al-Khalifa, who attended the Grand Prix, said in a statement overnight he wanted "to make clear my personal commitment to reform and reconciliation in our great country. The door is always open for sincere dialogue amongst all our people."
Protests peaked on Friday, usually a day of protest in the Arab world that falls on the weekend, when over 10,000 rallied. An estimated 7,000 gathered on Saturday and there were no signs of mass gatherings on Sunday, a regular workday.
After the race, police used teargas to stop demonstrators in several Shi'ite villages around Manama, rights activist Sayed Yousif al-Muhafda said.
Muhafda said authorities did not want the funeral for Habib t o take place while many foreign journalists were still in the country for Formula One.
"They don't want journalists to see the body while the Formula One race is still on and they know many journalists will go to the funeral. Maybe they will release the body tomorrow or the next day," Muhafda said.
Staff of two teams witnessed petrol bomb-throwing incidents and some members of the Force India team left Bahrain. But most of the travelling Formula One entourage have had no interaction with the violence taking place mainly outside the capital.
Bahrain's government is thought to have paid $40 million to host the event, a symbol of pride for the ruling family since it brought the first Grand Prix to the region in 2004. When it was last held in 2010, the race drew more than 100,000 visitors and generated $500 million in spending.
" The excitement and quality of the racing is a fitting conclusion to another enthralling weekend of racing at the Bahrain International Circuit," said Zayed Al Zayani, circuit chairman.
While motor sports journalists were invited to cover it, reporters from Reuters and some other news organisations who normally write about Middle East politics were denied visas.
Hackers brought down the F1 website intermittently on Friday and defaced another site, f1-racers.net, to support what they described as the Bahraini people's struggle against oppression.
The F1 website was back up on Sunday.
The hunger strike of Abdulhadi al-Khawaja, one of 14 men jailed for leading last year's uprising, has further inflamed anger on the street. His health has entered a critical stage after more than 70 days. His family said he stopped taking water on Friday, raising fears for his life.
Bahrain's state news agency said Khawaja was in "good health and stable and receiving full medical attention," citing Attorney General Abdelrahman al-Sayed, after a visit by a public prosecutor.
Khawaja also met on Sunday with the ambassador from Denmark, where he also holds citizenship, and which has asked for Khawaja to be released into their care, the agency said.
