An unidentified assailant fired gunshots at the headquarters of Turkey's main pro-Kurdish party overnight Friday, but there were no casualties, media said yesterday, in an attack which could stir tensions ahead of a June general election.

Bullets were fired through the sign outside the Peoples' Democratic Party (HDP) offices in the Turkish capital Ankara, Dogan news agency reported. No other damage was reported. The HDP is aiming to exceed the threshold of 10 percent of the vote needed to enter parliament in the June 7 election and opinion polls indicate its support is currently around that level.
