The Nationalist Movement Party (MHP) election bureau in Istanbul's Okmeydani neighborhood has been attacked by unknown people with Molotov Cocktails and gun shots.
The police said the bureau was empty at the time of the attack, which took place Feb. 6 at around 11 p.m.
The attack comes in the wake of a gun assault on the party's campaign office two weeks ago that killed an adviser, Fatih Akyildiz, and injured seven members.
Another gun assault carried out Jan. 27 targeted the municipal building in Şişli in an apparent attempt to target Şişli mayor Mustafa Sarigul. Sarigul is the main opposition Republican People's Party's (CHP) mayoral candidate for Istanbul in the March 30 local elections.
The MHP's Beyoglu district branch head Murat Dogan said Okmeydani was a problematic area, and stressed that current security measures were insufficient.
The party's candidate for Beyoglu, Osman Gur, suggested that more attacks would take place before the elections. "We are encouraging all institutions to prevent similar incidents from happening again," Gur said.
Following the Esenyurt attack, MHP head Devlet Bahceli urged the ruling Justice and Development Party (AKP) to shed light on the incident, while the government has vowed to take additional security measures ahead of the elections.
