Dozens of people have reportedly attacked the booths of opposition Good Party in Istanbul’s Avcilar, injuring 5 people including the party’s Avcilar representative Gokhan Yigit, on Sunday.

Media reported that the attackers first gathered alongside the pro-government Nationalist Movement Party (MHP) stall nearby and then approached to Good Party booths when Yigit showed up.

4 people were injured with knife while the other was subjected to gun attack, according to media.

One of the injured was in critical condition, receiving treatment at Istanbul’s Capa Medical Faculty hospital at the time of writing.

Last week, an unknown group of people have attacked opposition Felicity Party (SP) stand in Ankara marking the first of such attacks in Turkey’s 2018 election period.

SP and Good Party earlier allied to challenge President Recep Tayyip Erdogan, the joint candidate of the ruling AK Party and MHP, in snap presidential elections on June 24, this year.
