Dozens of Turkish anarchists gathered in Kadıköy to protest on the anniversary of the 19 December massacre, better known as Operation "Return to Life". The protesters were attacked by Turkish police, with 10 arrests made. Prisoners were protesting the government plan to transfer prisoners to American-style "F-type" cells holding 1-3 occupants, in response to which 10,000 soldiers violently occupied 48 prisons to end 2 months of hunger strikes by hundreds of political prisoners. At least 31 prisoners were murdered by the Turkish government, 8 others were disappeared, and 426 prisoners were wounded. 1005 prisoners were then caged in the F-type cells.
