IZMIR, Turkey — A gunman attacked the headquarters of the pro-Kurdish Peoples' Democratic Party (HDP) in Izmir, the third-largest city of Turkey, June 17, killing a 38-year-old volunteer.

The gunman’s initial statement said that he acted alone, but several opposition politicians demanded further inquiry into his ties, particularly after his Instagram account showed him toting guns in Manbij, Syria. HDP members also accused the government of making the party a target with repetitive accusations that HDP was a threat to national security.

“This was an attack that was coming,” HDP co-chair Mithat Sancar said at a press conference in Ankara. “This government feeds on chaos and tries to stifle the opposition, particularly the HDP, through all means. Those who have not dealt with us through legal and political means have now mobilized their killers. The government has put its chaos plans into action.”

He added that the attack could have become a massacre if the HDP had not decided at the last minute to postpone a meeting of 40 local chairs scheduled for the morning.
