The head of the pro-Kurdish opposition HDP party Selahattin Demirtas has accused the ruling AKP of orchestrating nationalist attacks and pushing Turkey towards civil war, BBC reports.
Demirtas accused the prime minister and President Recep Tayyip Erdogan of taking "the decision to start this war and intensify it".
No-one has been killed, but Demirtas said his supporters were facing a "campaign of lynching".
In his turn HDP lawmaker Garo Paylan complained that police stood by as the party building was attacked.
"Police are just watching, he said. "What's being broken there is our hope of living together."
