He told the crowd: “People of Harmanli want to live in safety, not to be ill from sicknesses unknown from 100 years ago in Europe, carried by some Afghan farmer.
“People do not want to meet these people at night.”
The Harmanli refugee centre is expected to increase capacity to exceed 3,000, in a town with just over 18,000 residents.
Officials plan to eventually expand this to nearly 5,000 – meaning that nearly one in three of those in the remote Bulgarian town could be a refugee in the next year.
The October demonstration was also fuelled by concerns about possible violence and petty crime, as the locals claimed there have been incidents involving some of the camp residents over the past years.
In September, a mass brawl between two groups of 800 migrants – from Iraq and Afghanistan – prompted the police to intervene and a strict ban on drinking alcohol was enforced in the camp.
A speaker at the October protest against the migrant camp said: “We don’t want them in the town at all, or at least they should be locked up and not allowed in the town.”
“Someone has artificially planted 3,500 individuals who have an unclear status they are totally incompatible with our culture and are people we do not wish to see.
“Of course, we are terrified. This place becomes inaccessible to locals in the evening. It is taken over by Afghans and it becomes unsafe.
“Refugees are constantly being settled here. Their number is up to 3,500.”
A number of other anti-migrant marches have also been staged around Bulgaria, including in the capital Sofia.
