F1 Bahrain Violence: Protesters in the capital Manama began their 'three days of rage' on Friday

Tens of thousands of anti-government protesters are set to intensify demonstrations in Bahrain ahead of tomorrow's Grand Prix following a day of violent clashes in the Gulf state.

Around 50,000 activists gathered in the capital Manama yesterday as Formula One drivers took to the track of Bahrain International Circuit, just 25 miles away.

Thousands more are expected to take to the streets today calling for the cancellation of the controversial motorsport event.

The protesters started their so-called "three days of rage" yesterday against Bahrain's rulers.

Petrol bombs were hurled at security officials and anti-grand prix graffiti was daubed on walls, before the protesters were dispersed with tear gas and pepper spray.

Despite months of political unrest and the regime's crackdown on demonstrators, F1 organisers have refused to scrap the three-day event. Read More
