SOFIA, Bulgaria (AP) — Police and migrants have clashed at a refugee camp in southern Bulgaria, leaving several offices injured.

District police spokeswoman Nina Nikolova said some 2,000 migrants were involved in the scuffles on Thursday. Shouting slogans, they allegedly set tires and furniture on fire and threw rocks at police.

The clash reportedly broke out after migrants complained about the camp being isolated following an alleged outbreak of infectious diseases.

Later Thursday, police said the situation was under control and negotiations were to be held with the protesters.

The head of the state refugee agency, Petya Parvanova, says there was no medical reason to quarantine the camp, but that local authorities had sealed it off after local residents protested.

About 3,000 people are staying at the camp in Harmanli, near the border with Turkey.
