Around 2,200 protesters have demonstrated in 14 Bulgarian cities this week after a dispute between a Roma leader and villagers led to an outbreak of violence.

More than 160 people were arrested during the protests against Bulgaria's Roma, or Gypsy, minority.

The unrest broke out after the death of a 19-year-old man, which some have linked to 69-year-old Roma clan leader Kiril Rashkov.

Rashkov has been arrested for allegedly making death threats. Several of his houses and cars have been set on fire.

There is widespread intolerance towards the Roma minorities across much of Europe.
