At least 34 people have been detained during demonstrations to mark 44th anniversary of Deniz Gezmiş and his friends’ execution by the government on charges of attempting to overthrow the constitutional order in 1972.

Three student leaders Deniz Gezmiş, Yusuf Aslan and Hüseyin İnan were hanged at a prison in Ankara’s Ayaş district for attempting to overthrow the constitutional order as an junta-backed government voted to approve their death penalties, just two years after the 1971 military coup.

The three have become rallying figures among leftist circles since their deaths.

A group of leftist party members gathered at Candoğan park in the western province of Denizli to mark the executions while police, calling the demonstration unauthorised, intervened into the group and detained 34 protesters.
