F1 chief Ecclestone: Sport and politics should not mix- Most teams have maintained they are happy to race in Bahrain but one of Force India's drivers, Nico Hulkenberg, was quoted by BBC Sport as saying: "We shouldn't have been put in this position." At a demonstration on Monday in Al Dair, in the north east of Bahrain, many pro-democracy protestors carried anti-F1 slogans. More action is expected to be planned around the weekend's event. Bernie Ecclestone, the head of Formula One, has continually insisted that sufficient security measures are in place in Bahrain and that the sport had nothing to do with the politics of the country. A statement from the Bahrain International Circuit confirmed the incident had taken place but underlined that the Force India group had not been singled out for any violence. "They drove through an isolated incident involving a handful of illegal protestors acting violently towards police," it read. During this incident a Molotov Cocktail landed in the vicinity of their vehicle. After approximately two minutes, the route was cleared and the vehicle carried on its journey. There were no casualties and eyewitness reports from the scene confirmed that their vehicle had not been targeted itself. The BIC would like to reiterate its confidence in the relevant Bahrain authorities in their ability to deal with such isolated incidents and can confirm that all the usual precautions are being taken around the track to ensure the level of security is maintained.
