In short: A peaceful protest to protect the last public park in Istanbul's center from being a shopping mall, turned into a big nation-wide demonstration upon unbalanced use of force (gas bombs, water cannons, beating) by police, leaving many severely injured, some killed. The prime minister, who's been governing the country as almost a dictator, ignores the public opinion, does not take action, and threatens the demonstrators. Worse, police violence and demonstrations in over 40 cities didn't take place in Turkish TVs, for first 3 days of the demonstrations which apparently have fear of the government, as many anti-government journalists are in prison, since the judiciary has been taken over by pro-government officials.
Brutality in numbers: 11 dead, more than 8000 got injured.
(Update July 2014 - 17 dead)
